The present study was conducted to provide the anthropometric measurements and energy intake of male university students. Edible plate waste was assessed. A total of 90 male students participated in the anthropometric study. Meal and edible plate waste were analyzed for their contents of moisture, crude protein, crude lipid, ash and fiber. Total carbohydrates were calculated by difference. Total served meals and edible plate waste were assessed quantitively using a weight technique. Total energy intake was 85% of the RDA. The students had higher intakes of protein and fat and lower intakes of carbohydrate than the recommended levels. The collected data showed that plate waste was influenced by the timing of the meal. Plate waste was higher for dinner (39.74%) and lower for lunch (22.67%).

Abstract This trial was located at the Staples Irrigation Station in Staples, MN. Soils were irrigated sandy loams. Plots were 2 rows X 9.15 m in length. Treatments were arranged in a randomized complete block design and replicated 4 times. The plot rows were marked with the planter and a 1:1:1 bait mixture of bone meal, blood meal, and meat scraps was applied four days prior to planting. Approximately 102 kg of this mixture was applied to the plot area. The seed was treated with a sticker, coated with the appropriate seed treatment, allowed to dry, and planted 27 May using a John Deere Maximerge planter. Granular insecticide treatments were applied in a 15.2 cm band on the row following planting. The field was then irrigated to ensure rapid and uniform germination. Stand counts and yield were taken from two 3.05 m lengths of row. The threshed seed was cleaned, dried, moisture level determined, and final yields adjusted to a standard moisture.

The study was carried out to evaluate the effect of mulberry (Morus alba) leaf meal levels on growth performance and carcass characteristics of Tigray highland lambs. The experiment consisted of five treatments; and conducted in a randomized complete block design using thirty intact yearlings Tigray highland male lambs. The experimental diets were 300g concentrate mix alone, 225g concentrate mix + 86.55g mulberry leaf, 150g concentrate mix + 173.1g mulberry leaf, 75g concentrate mix + 259.7g mulberry leaf and 346.2g mulberry leaf alone with barley straw ad libitum to all treatments. The mix was prepared from Noug seed cake and wheat bran at ratio of 1:2, respectively. Higher weights of total edible offal component, empty body weight, rib eye muscle area and slaughter weight were observed as a result of high level of mulberry leaf meal supplementation than the sole concentrate mix treatment. On the other hand, the dressing percentage on slaughter weight base as well as empty body weight base and hot carcass weight showed less difference (p>0.05) between sole mulberry leaf meal and sole concentrate mix treatments. The result of the present study indicated that substitution of mulberry leaf meal for concentrate mix can be used effectively without affecting the results of growth parameters as well as edible or non edible offal components that can be achieved by sole concentrate supplementation. Hence, the finding revealed that feeding mulberry leaf meal alone to Tigray highland lambs could substitute the costly and even less accessible commercial concentrate mix to resource poor farmers and could result in reasonably better performance of lambs.

Full textAbstract:
Ethnobotanical studies have shown that many wild plant species are sporadically consumed alongside regular food sources in developing countries. Many plants of wild and semi-wild origin are consumed in the remote parts of southern Ethiopia. Dietetic values of Ethiopia’s non-crop food plants, though important in prevention of malnutrition and contribution to food security, remains shrouded for lack of chemical information. The chemical composition of popularly used wild edibles in Hamar and Konso (Xonso) of southern Ethiopia was examined. The most preferred 15 semi-wild and wild edible plants were selected using a mix of standard ethnobotanical field methods. Edible parts of target plants were collected with local participants, lyophilized and analyzed for proximate composition, amino acids, minerals and antinutritional factors. The wild edibles constituted good amounts of nutrients essential in human diet. Green leafy vegetables (GLVs) gave 1.5-5.8% ether extractives and total mineral composition of 12.5%-25.6%; Ca being highest (1100 - 3419 mg %) and exceptionally high for Justicia ladanoides (6177 mg %). Fe, Mg, Mn and Zn ranged from 11.7-23.14, 175-2049, 3.4-9.9 and 1.2-3.3 mg %, respectively. All GLVs contained ≥20% protein, highest in Coccinia grandis (36.3%). The latter species and Trigonella foenum-graecum yielded high lysine level. Anti-nutrients of concern include phenolics (158-1564 mg %) and tannins (448-2254 mg %) in GLVs and phenolics (1997mg %) and tannins (6314 mg %) in Ximenia caffra fruits. Total oxalates in mg % were high in Amaranthus graecizans (14067), Celosia argentea (12706) and Portulaca quadrifida (10162). Bulk consumption of monotype edible plant part in one meal may lead to nutritional and health impairment. However, traditional processing methods lower most of the anti-nutritionals and their respective risks. New food composition tables that integrate indigenous knowledge and nutritional content of the semi-wild and wild edibles are recommended. Wild edibles can be considered to improve livelihood security and reduce malnutrition in tune with the Millennium Development Goals aimed at reducing poverty and hunger.

Two surveys were conducted to determine the importance of characteristics of containers of edible flower which could be sold to consumers in retail outlets. Self-selected participants at Bloomfest at Cobo Hall in Detroit, Mich., were assigned to one group that rated the importance of attributes such as edible flower color of Viola × wittrockiana `Accord Banner Clear Mixture', color combinations, container size, and price of the container. Participants assigned to a second group rated color, color combinations, and size. Flower color was allocated the most points in the purchasing decision (63% for the first group and 95% for the second group), with a mixture of all three colors (blue, yellow, and orange), proving to be the most desirable. Responses were subjected to Conjoint Analysis (SPSS Inc., Chicago), which resulted in the formation of three groups of customer segmentation. The groups were labeled “Likely Buyer” who had eaten and purchased edible flowers before and rated characteristics of edible flowers favorably; “Unlikely Consumer” who had eaten edible flowers before and had rated characteristics of edible flowers unfavorably; and “Persuadable Garnishers” who had not eaten edible flowers before, but were very likely to purchase edible flowers for a garnish for a meal.

Full textAbstract:
Edible insects represent an interesting alternative source of protein for human consumption but the main hurdle facing the edible insect sector is low consumer acceptance. However, increased acceptance is anticipated when insects are incorporated as a processed ingredient, such as protein-rich powder, rather than presented whole. To produce edible insect fractions with high protein content, a defatting step is necessary. This study investigated the effects of six defatting methods (conventional solvents, three-phase partitioning, and supercritical CO2) on lipid extraction yield, fatty profiles, and protein extraction and purification of house cricket (Acheta domesticus) and mealworm (Tenebrio molitor) meals. Ethanol increased the lipid extraction yield (22.7%–28.8%), irrespective of the insect meal used or the extraction method applied. Supercritical CO2 gave similar lipid extraction yields as conventional methods for Tenebrio molitor (T. molitor) (22.1%) but was less efficient for Acheta domesticus (A. domesticus) (11.9%). The protein extraction yield ranged from 12.4% to 38.9% for A. domesticus, and from 11.9% to 39.3% for T. molitor, whereas purification rates ranged from 58.3% to 78.5% for A. domesticus and from 48.7% to 75.4% for T. molitor.

Full textAbstract:
Edible oil extraction is a large and well-developed sector based on solvent assisted extraction using volatile organic compounds such as hexane. The extraction of oil from oilseeds generates large volumes of oilseed by-products rich in proteins, fibres, minerals and secondary metabolites that can be valued. This work reviews the current status and the bio-macro-composition of oilseeds, namely soybean, rapeseed, sunflower and flaxseed, and the refining process, comprising the extraction of oil, the valorisation and separation of valuable secondary metabolites such as phenolic compounds, and the removal of anti-nutritional factors such as glucosinolates, while retaining the protein in the oilseed meal. It also provides an overview of alternative solvents and some of the unconventional processes used as a replacement to the conventional extraction of edible oil, as well as the solvents used for the extraction of secondary metabolites and anti-nutritional factors. These biologically active compounds, including oils, are primordial raw materials for several industries such as food, pharmaceutical or cosmetics.

Full textAbstract:
Inclusion of edible insects in human diets is increasingly promoted as a sustainable source of proteins with high nutritional value. While consumer acceptability remains the main challenge to their integration into Western food culture, the use of edible insects as meal and protein concentrate could decrease neophobia. The defatting of edible insects, mostly done with hexane, is the first step in producing protein ingredients. However, its impact on protein profiles and techno-functionality is still unclear. Consequently, this study compares the protein profiles of hexane-defatted and non-hexane-defatted yellow mealworm (Tenebrio molitor) meals and protein extracts, and evaluates the impact of hexane on protein solubility and foaming properties. Results showed that profiles for major proteins were similar between hexane-defatted and non-defatted samples, however some specific content differences (e.g., hexamerin 2) were observed and characterized using proteomic tools. Protein solubility was markedly lower for T. molitor meals compared to protein extracts. A large increase in the foaming capacity was observed for defatted fractions, whereas foam stability decreased similarly in all fractions. Consequently, although the hexane-defatting step was largely studied to produce edible insect protein ingredients, it is necessary to precisely understand its impact on their techno-functional properties for the development of food formulations.

Full textAbstract:
Purpose: The purpose of this qualitative research paper was to explore how consumers with an environmental identity evaluate new, environmentally friendly substitutes for meat, with edible insects given as an example. Problem: An increasing number of Swedish consumers show an overall negative attitude towards consuming meat, mainly due to environmental concerns, and express this by identifying themselves as vegetarians or flexitarian. Edible insects possess the potential to become an environmentally friendly, nutritious and innovative meat substitute in Sweden. Although the demand for new environmentally friendly meat substitutes is high, the intentions of consuming edible insects are low in Western societies. This causes researchers to ask why this conflict is. Methodology: In order to fulfill the purpose and to answer the research question, a qualitative research approach was adopted. Eight semi-structured interviews were used in the empirical data collection process. The chosen target group was vegetarians and flexitarians of Generation Y, and the sample was chosen through judgmental sampling. Findings: This empirical study examines an extensive confusion and conflicted standpoints among consumers when evaluating edible insects. However, the authors examine a high willingness and positive attitude towards consuming edible insects. Five key factors that influence the evaluation of edible as a meat substitute have been identified: the animalistic qualities of insects, if insects are perceived as meat or vegetarian, if edible insects are ‘green’, proof and facts, and what product category edible insects belong to.

Full textAbstract:
In this thesis, Margaret Atwood’s The Edible Woman and Michel Faber’s Under the Skin are analysed from the perspective of feminist-vegetarian critical theory. Both texts deal with the idea of feeling like or being meat, but approach this idea from different angles. In The Edible Woman, the connection to feeling like meat is metaphorical and rooted in gender relations, while in Under the Skin, it is literal, related to the idea of being animal. What becomes clear through an analysis of these two texts is that they both deal with the interlocking oppressions of women and animals. In The Edible Woman, protagonist Marian loses her subjectivity and stops eating meat when, as a result of the dynamics of her relationship with her boyfriend (later fiancé), she starts identifying with animals that are hunted or eaten. In Under the Skin, the alien protagonist Isserley, as female, non-human and in her natural form looking like a kind of mammal, represents both women and animals in her objectifying returned gaze on human men. Examining these two texts together highlights the interlocking nature of patriarchy and speciesism, and shows how these oppressions are better understood in relation to each other.

Full textAbstract:
Replacing meat from animals with cultured meat and edible insects might reduce the impact on climate and the environment. That said, in order to fulfill their function as a sustainable food, insects and cultured meat would need to be consumed, on a wider scale and with a real-time reduction in meat consumption. The aim of this study was to explore consumers' attitudes toward consuming insects and cultured meat, whilst gathering an understanding of what consumers, themselves, believe to be acceptable to consume in the future. Fifteen individual semi-structured interviews, of both men and women, were conducted outside a supermarket in central Sweden. Data was transcribed and analyzed thematically. The results highlight that for some respondents, insects are perceived as alien and undesirable, while cultured meat was perceived as too unnatural to be eaten; whilst others expressed both reluctance and a curiosity towards cultured meat and edible insects. Most respondents believed they will eat less meat, more vegetables and vegetarian protein in the future, and might try insects and cultured meat in hidden forms such as in sausage. The conclusion was that consumers had a mixed attitude toward eating insects and cultured meat.Enligt FN och FAO måste matvanorna i västvärlden ändras eftersom de inte är hållbara. Jordbruket orsakar utsläpp av stora mängder växthusgaser, och köttproduktionen står för den allra största delen av dessa. Ätbara insekter och odlat kött kan vara alternativa proteinkällor till exempelvis kött, de är mer miljövänliga med avseende på koldioxidutsläpp, vattenförbrukning, markanvändning och energiåtgång. För att livsmedlen ska fylla sin funktion som hållbara proteinkällor så krävs det att de konsumeras av befolkningen. Syftet med denna studie var att studera svenska konsumenters attityder till att äta insekter och odlat kött, samt att undersöka vad konsumenterna själva tror att de kommer att äta i framtiden. Studien är kvalitativ med en fenomenologisk ansats. Data insamlades med hjälp av intervjuer. 15 personer i olika åldrar deltog i studien, varav 8 kvinnor och 7 män. Resultatet visade att det finns en blandad attityd till att äta insekter och odlat kött. Insekter upplevdes som främmande och äckligt, och odlat kött som alltför onaturligt för att ätas. Det fanns både en tveksamhet och en nyfikenhet hos respondenterna till dessa alternativa proteinkällor. Hos de som hade en positiv attityd till att äta livsmedlen uppgavs miljövinsterna som främsta anledning till att konsumera dem. Hos de som hade en negativ attityd angavs känslor av äckel som främsta anledning till att inte konsumera insekter och odlat kött. Om insekterna eller det odlade köttet var dolt såsom i korv kunde vissa respondenter tänka sig att äta. Faktorer som ett fördelaktigt pris, god tillgänglighet och att produkter baserade på odlat kött och insekter är godkända enligt livsmedelslagstiftning, påverkade respondenternas villighet att konsumera dessa. Respondenterna trodde framförallt att de kommer att äta mindre kött, mer grönsaker och mer vegetariskt protein i framtiden. Slutsatsen är att det finns både positiva och negativa attityder till att äta insekter och odlat kött. Viljan att konsumera produkter baserade på dessa livsmedel verkar öka om livsmedlet är dolt, såsom i korv. Detta gäller både för insekter och odlat kött.

O objetivo deste estudo foi avaliar o desempenho, a composição e o perfil de ácidos graxos (AG) do leite e da carne de ovinos alimentados com dietas contendo óleo de canola, girassol ou mamona. Adicionalmente, foram realizados dois ensaios de metabolismo para avaliar o efeito das dietas sobre a digestibilidade dos nutrientes e parâmetros ruminais. No Experimento I, 44 ovelhas com suas respectivas crias foram distribuídas em delineamento em blocos completos casualizados. Os animais foram alimentados com dietas compostas por 50% de volumoso, sendo uma dieta controle e as outras contendo 3% de óleo de canola, girassol ou mamona. A adição de óleo reduziu o consumo de matéria seca (CMS) e aumentou o consumo de extrato etéreo. Não houve alteração na produção de leite e desempenho das crias. A adição de óleo de mamona aumentou o teor de gordura e sólidos totais do leite. A adição de óleos de canola e girassol reduziu as concentrações de AG de cadeia curta (AGCC), de cadeia média, saturados e o índice de aterogenicidade; e aumentou as concentrações de C18:0, C18:1-9, C18:2 cis-9, trans-11 (CLA), C18:1 trans-11, AG de cadeia longa, AG monoinsaturados e AG insaturados totais. Estes óleos aumentaram ainda, a relação entre AG poliinsaturados:saturados (P:S) comparado à dieta controle. No experimento II, quatro ovinos canulados no rúmen, foram distribuídos em um delineamento em quadrado latino 4 x 4 para avaliar as dietas utilizadas no Experimento I. Não houve diferença no CMS e digestibilidade dos nutrientes. A adição de óleos aumentou os valores de pH ruminal e reduziu as concentrações de AGCC. No experimento III, foi analisado o desempenho de 36 cordeiros mestiços Dorper x Santa Inês alimentados com rações com 90% de concentrado e 3% de óleo de canola, girassol ou mamona. Não houve diferença no CMS, ganho de peso médio diário (GMD) e conversão alimentar, sendo a média das dietas de 957,7 g, 326,4 g e 3,0 kg MS/kg GMD, respectivamente. Adicionalmente, foi realizado um ensaio de metabolismo com quatro ovinos canulados no rúmen em um delineamento em quadrado latino 4 x 4. Não houve diferença (P>0,10) no CMS, digestibilidade dos nutrientes, balanço de nitrogênio e nos parâmetros ruminais, com exceção da amônia, que diminuiu com a adição de óleos. No experimento IV, foram avaliados: as características da carcaça, composição físicoquímica e perfil de AG do músculo Longissimus dorsi dos cordeiros do experimento III. A adição de óleo de mamona elevou o teor de extrato etéreo da carne. O óleo de girassol reduziu a concentração de C18:1 -9, e aumentou a concentração de C18:1 trans. A adição de óleo de mamona reduziu a concentração de C18:2 e a relação P:S na carne em comparação aos óleos de canola e girassol. A inclusão de óleos de canola e girassol reduziu a concentração de C16:0, aumentou a concentração de C18:2 cis-9, trans-11 (CLA) e C18:3 -6. O óleo de canola aumentou a concentração de C18:3 -3 e o óleo de girassol aumentou a relação 6:3 comparado ao óleo de mamona.The objective of this study was to evaluate the performance, milk composition, meat and milk fatty acid profile of ewes and lambs fed diets containing canola oil, sunflower oil or castor oil. Additionally, two metabolism trials were conducted to determine the effects of the diets on nutrient digestibility and ruminal measures. Experiment I: 44 Santa Inês ewes with lambs were allotted in a randomized complete block design and fed a control diet (no oil) containing 50% roughage or diets with the addition of 3% of canola oil, sunflower oil or castor oil. The addition of oil decreased DM intake and increased ether extract intake. However, there was no effect on milk production and lamb performance. The percentage of milk fat and milk total solids increased with castor oil. Diets with canola and sunflower oils decreased short chain fatty acids (FA), medium chain, saturated FA and atherogenicity index; and increased C18:0, C18:1-9, C18:2 cis-9, trans-11 (CLA), C18:1 trans-11, long chain and monounsaturated FA. In addition, these diets increased polyunsaturated:saturated (PUFA:SFA) ratio compared to the control diet. Experiment II: Four ruminally cannulated ram lambs were assigned to a 4 x 4 Latin Square design to determine the effects of the diets used in Experiment I on intake, nutrient digestibility and ruminal measures. There was no difference (P>0.10) on DM intake and nutrient digestibility. The oil addition increased pH values and decreased short chain FA. Experiment III: the objective was to evaluate the performance of 36 crossbred Dorper x Santa Inês lambs fed diets with 90% concentrate hay with 3% canola oil, sunflower oil or castor oil. There was no difference on DM intake, average daily gain (ADG) and feed conversion, with average across diets of 957.7 g, 326.4 g and 3.0 kg DMI/kg ADG, respectively. These diets were also evaluated in four ruminally cannulated ram lambs in a 4x4 Latin Square design. There was no difference in DM intake, nutrient digestibility, nitrogen metabolism and ruminal measures, with the exception for ammonia concentration that decreased with oil addition. In the Experiment IV were determine: carcass characteristics, Longissimus dorsi fatty acid profile and physical-chemical composition of the lambs used in Experiment III. The diet with castor oil increased meat ether extract. Sunflower diet decreased C18:1-9 and increased concentrations of C18:1 trans. Castor oil decreased the concentration of C18:2 and PUFA:SFA ratio compared to canola and sunflower oils. Canola and sunflower decreased the concentration of C16:0, increased the concentration of C18:2 cis-9, trans-11 (CLA) and C18:3 -6. Canola oil increased the concentration of C18:3 -3 and sunflower oil increased 6:3 ratio compared to castor oil.

The purpose of this study is to analyze proximate compositions, free amino acids (FAA), minerals, trace elements and heavy metals in edible seaweed samples. They were 6 kinds of red seaweed and brown seaweed, and 2 kinds of green seaweed samples which were collected from the market. There are significant differences in proximate composition among seaweeds. The moisture in 14 kinds of seaweed ranged from 7 to 44%¸ ash 2 to 28%, and crude protein 2 to 28%. Trace amounts of crude lipid were found in all samples. The pH value in the seaweed products was between 5.78-10.21. Red seaweed was in a weakly alkaline ranged from 6.67 to 10.21, and brown and green seaweed were in a weakly acidity from 5.78 to 7.00. Some seaweeds had much higher pH value. It might due to wash and clean seaweeds with alkaline solvent during processing. There is remarkable difference in the content of free amino acid (FAA) among species. Saccharina japonica and Durvillaea antarctica had high levels of FAA with 1716-2671 mg/100g, but those of Eucheuma denticulatum, Eucheuma serra and Undaria pinnatifida were lower than 100 mg/100 g. Porphyra dentata had more kinds of FAA among samples. Brown seaweeds possessed higher amounts of aspartic acid, glutamic acid and alanine. For Ulva lactuca, it had much more taurine than any other seaweeds. There is remarkable difference in the contents of minerals in seaweeds. The amount of sodium ranged 706-91975 ppm, potassium 991-88191 ppm, calcium 1847-29453 ppm, and magnesium 1170-37915 ppm were found in seaweeds. For the trace elements in the seaweed products, the amount of iron was 36-927 ppm, manganese 0-5.76 ppm, chromium 0-0.04 ppm, copper 0.8-21.4 ppm, and zinc 1.28-23.13 ppm. The amounts of trace elements showed significant difference in different species of seaweeds expect for chromium. Even the same species of Ulva lactuca, the contents of iron and manganese in different samples also showed remarkable difference. There was 3.46 ppm of lead in Gelidium amansii, but other seaweeds has less. The average amount of lead in red seaweed was higher than those of brown and green seaweed. According to food sanitary standards, all samples meet the regulation limit as calculated the moisture of seaweed with 85% of moisture such as fresh one. Cadmium was found in samples, but all are under the limit. The contents of mercury ranged from 0.02-0.04 ppm which was in compliance with the limit. The high levels of aluminum were found in Gelidium amansii (809 ppm), KappapHycus alvarezii (461 ppm) and PorpHyra dentate (357 ppm). The use of aluminum as leaveners in those seaweeds may result in high levels of aluminum in the products. The amount of arsenic in the seaweed products was between 0.84-46.36 ppm. Inorganic arsenic As2O3 and NaAsO3 of the samples do not exceed the regulation limit 1 ppm after converting the moisture of seaweed to 85%. The results could provide the information regarding basic nutrient substances, flavor compounds, trace elements, minerals and heavy metals in seaweeds. It also could be a reference for consumers to purchase edible seaweed and for government agency to set the limit standard of seaweed.

Full textAbstract:
Porphyra abbottiae Krishnamurthy (Rhodophyta) is an intertidal red alga harvested by a number of coastal First Nations in British Columbia. The Kwakwaka’wakw have a long history of harvesting P. abbottiae as food and medicine, reflected in the language, songs and stories of the Kwakwaka’wakw oral tradition. Harvesting and drying practices for this alga have undergone changes with the introduction of new technologies and a decrease in time available for seaweed harvesting. The adoption of timesaving equipment into the seaweed harvest has given harvesters the flexibility to work around constraints including work and school obligations, tides, long distances to harvesting sites, and unpredictable weather conditions. Harvesting and drying practices reflect a thorough understanding of the lifecycle, biology, and ecology of P. abbottiae. Timing of the harvest during the seasonal round optimizes the taste and texture of P. abbottiae fronds while avoiding the seaweed in its reproductive stage. Songs and taboos associated with the harvest promote safety and efficiency while harvesting the seaweed.
Concerns about potential contamination of edible seaweed led to the second part of this research: testing for metal contamination. Inductively coupled plasma mass spectrometry analysis for selected metals and trace elements revealed the presence of arsenic, cadmium, lead, and mercury in Porphyra abbottiae sampled from the southern Queen Charlotte and Broughton Straits. Mercury concentrations fell below the detection limit of 0.01 ng/mL in 28 of 112 samples. Calcium was the most abundant element measured, averaging 1445 mg/kg dry seaweed. The remaining metals, in decreasing order of concentration, are: Fe>As>Zn>Mn>Cu>Cd>Pb>Cr>Co>Se>Hg. Copper-zinc (r=0.835) and copper-lead (r=0.948) concentrations are significantly correlated (p<0.05), suggesting selective uptake of these elements. PCA analysis suggests that the location of harvesting sites within specific water channels is influencing metal concentrations. Hazard quotients calculated using guidelines set by Health Canada and the World Health Organization revealed that, among the suite of elements surveyed, arsenic followed by cadmium ranked the highest in relative risk for consumers of P. abbottiae. An average 60 kg adult consumer can safely consume approximately 9.4 g dried seaweed per day and not exceed tolerable upper intake limit guidelines. In conclusion, Porphyra abbottiae can be eaten in moderation with minimal risk of chronic metal contamination. Kwakwaka’wakw consumers can also benefit from cultural reconnection with this important traditional food.Graduate

Full textAbstract:
In Edible Insects and Human Evolution, Julie Lesnik investigates insects in the human diet from an evolutionary perspective. In May of 2013, the United Nations Food and Agriculture Organization proposed that insects as food should be strongly considered as a means of addressing the increased food demands of our growing global population. One area of investigation proposed by the FAO included more thoroughly understanding the nutritional value of insects in order to promote them as a healthy food choice. This book not only reviews the available evidence of insect nutritional values, but also explores the roles different nutrients play in human reproduction and development. Over the course of our evolution, our nutritional demands greatly increased, in part due to the evolution of our large brains. Insects are a high-quality food resource that was likely exploited by our ancestors in order to increase dietary quality during these critical times. Utilizing examples from hunter-gatherer populations as well as nonhuman primates, this book reconstructs the role of insects in the hominin diet over the course of human evolution. This low-risk food source would have offered nutrients that were otherwise difficult to obtain, making it especially appealing to females supporting young offspring. Historically, the literature surrounding the diet of our ancestors focused on hunting and meat eating, which has permeated into the current diet fad known as the paleo diet. This book argues that insects were just as important as meat in the past and that today they offer a sustainable alternative to meat.

Rapeseed-mustard belongs to the Brassicaceae family and is an important group of oilseed crops, used as spices, medicine and as a source of edible oil since ancient times. Brassica seed meal could be highly regarded as an important component of human nutrition and animal feed due to its good protein content (45-48%), desirable amino acid profile rich in lysine with adequate amount of sulphur containing amino acids and low antinutrient content. The defatted meal is a rich in bioactive principles responsible for health protection such as tocopherol, glucosinolates, phytic acid, carotenoides, folic acid, ascorbic acid, polyphenols and flavonols. The seed meal is characterized by appreciable antiradical activity along with better meal stability properties. The antioxidative properties of edible portions of Brassica are due polyphenolic components. The present review focused on literature available from the neutaceutical component of Brassica meal and its antioxdative properties.

Full textAbstract:
This article proposes to consider couscous, a North African specialty and a favourite dish of the French, as an edible site of memory. Displacing the focus from gastronomy, a discourse of national culinary superiority, to a single dish, I retrace the irresistible ascent of couscous to fame in the French culinary pantheon. The military conquest and colonization of Algeria familiarized French diners with the dish and associated it with forms of racialized and sexualized colonial burlesque in songs and vaudeville. Settlers appropriated it as terroir to claim their “Algérianité.” North African immigration and decolonization created a de facto market of consumers in France, while the industrialization of food production made this preparation into a valuable commodity and a ready-made meal, obfuscating its colonial roots. The French’s affection for couscous is often hailed as a sign of tolerance in an otherwise divisive and fraught public conversation about immigration, identity, and discrimination. However, couscous’ colonial baggage and racialized legacy continue to resonate, shaping tastes, and informing political rhetoric as well as cultural hierarchies. The (after)taste of empire lingers on at a granular level, as edible memory.

Objectives: Estimate the associations between cannabis use with expectations of cannabis being a sleep aid, subjective sleep outcomes, and the influence of age on these relationships. Methods: In 152 moderate cannabis users (67% female, mean age = 31.45, SD = 12.96, age range = 21-70) we assessed the influence of cannabis use history and behaviors on expectations of cannabis being a sleep aid and subjective sleep outcomes via the Pittsburgh Sleep Quality Index (PSQI). We used moderation analysis to examine the role of age in the relationship between cannabis use and subjective sleep outcomes. Results: Cannabis use along with more frequent cannabis use were associated with increased expectations that cannabis use improves sleep (all β > 0.03, p < 0.04). Frequency of recent cannabis use and reported average THC or CBD concentration were largely not associated with subjective sleep outcomes. However, endorsing current cannabis use was associated with worse subjective sleep quality (β = 1.34, p = 0.02) and increased frequency of consuming edibles was associated with worse subjective sleep efficiency (β = 0.03, p = 0.04), lower sleep duration (β = 0.03, p = 0.01), and higher global PSQI scores (worse overall sleep) (β = 0.10, p = 0.01). Furthermore, age was determined to have a moderating influence on the relationship between increased concentration of CBD and both better sleep duration and sleep quality (both p < 0.03). Conclusion: Cannabis users have higher expectations of cannabis being a sleep aid, but few associations existed between cannabis use and subjective sleep outcomes with the exceptions of endorsing any cannabis use and frequency of edible use. Additionally, age may be an important moderator of the potential positive influence CBD concentration can have on sleep.

This investigation focused on the combustion and performance of an indirect injection (IDI) diesel engine powered by a non-edible biodiesel blend, Brassica Carinata. This oilseed has become an attractive non-edible feedstock for biodiesel in the United States, given potential agronomical advantages. A small bore, single cylinder IDI engine was run at 2000 rpm and 5.5 bar indicated mean effective pressure (IMEP) using ultra-low sulfur diesel #2 (ULSD#2) and compared with C50, a 50% Carinata biodiesel-ULSD#2 blend (by mass). The apparent heat release for C50 reached a maximum of 22.04 J/deg which was 6.3 % lower and peaked 1.80 CAD before ULSD#2. The radiation and convection heat fluxes had similar maximum values of 0.62 MW/m2 and 1.34 MW/m2, respectively. The brake specific fuel consumption (BSFC) of C50 was 211.05 g/kWh, which was 9% higher than for ULSD#2. The mechanical efficiency was maintained relatively constant at 55% while the indicated thermal efficiency of the engine reached 59%. Both fuels produced similar nitrogen oxide (NOx) emissions with ULSD#2 and C50 producing 2.29 g/kWh and 2.23 g/kWh, respectively. The results indicate that the IDI engine can optimally work with concentrations up to 50% biodiesel.

Full textAbstract:
Abstract Acid treatments are commonly used in the oilfield to remove inorganic scale or to stimulate formatio ns. These treatments typically consist of using hydrochloric acid (HCl), acetic acid, formic acid, or chelating agents. At elevated temperatures, these acids are highly corrosive and can cause severe damage to tubulars as well as downhole equipment. To reduce damage from these acids, corrosion inhibitors are added to the treatment solution. Corrosion inhibitors used in the oil and gas industry are typically quaternary amines or sulfur-containing compounds. These compounds adsorb to the surface of the metal, thereby reducing contact between the metal surface and the corrosive substance. However, these corrosion inhibitors are damaging to the environment and harmful to human health. Alternative new environmentally-friendly corrosion inhibitors are also either toxic to the human body or face performance limitations at higher temperature field applications. To develop new environmentally friendly and non-toxic corrosion inhibitors for high-temperature applications, 15 edible seeds were tested as alternative sources of corrosion inhibitors. In order to determine the inhibition effect of 15 different seeds, N-80 and S13Cr coupons were exposed to 15 wt.% HCl solutions at temperatures between 77-250°F with 2 wt.% of grounded seed added for 6 hours. In addition, a control solution containing no corrosion inhibitor was used to establish a corrosion rate for a base case. This paper will show the results of such seeds and attempt to provide an awareness of natural seeds extract for use as corrosion inhibitors in conjunction with well acid treatments. It was noted that out of the 15 seeds, seeds 1 and 2 were found to perform the best at these conditions, exhibiting more than 90% corrosion inhibition efficiency. Seed 4 was observed to perform the worst, exhibiting only 16.8% inhibition efficiency. At 150°F, 2 wt.% of seeds 1 and 2 were tested with seed 1 achieving a corrosion rate of 0.00253 lb/ft2 while seed 2 was unable to provide sufficient inhibition with a corrosion rate of 0.153 lb/ft2. The control solution was found to have a corrosion rate of 0.371 lb/ft2 over the 6 hours at 150°F. Seed 1 was further tested at 200°F with the addition of corrosion inhibitor intensifiers and resulted in a corrosion rate of 0.00087 lb/ft2, while at 250°F, a corrosion rate of 0.00811 lb/ft2 was observed. The tests using S13Cr also showed that seed 1 worked well as a corrosion inhibitor for CRAs. The thermal degradation of seed 1 was also examined using NMR. These results show a new naturally occurring, green, non-toxic, high-temperature applicable corrosion inhibitor that can be developed from edible seeds.

Full textAbstract:
Increasing strict regulation on the sulfur content of diesel fuels results in decreases the lubricity of these fuels. The lubricity of the fuel is an indication of the amount of wear or scarring that occurs between two metal parts covered with the fuel as they come in contact with each other. Low lubricity fuel may cause high wear and scarring and high lubricity fuel may provide reduced wear and longer component life. Previous studies have shown that alkyl esters of triglycerides derived from vegetable oils have increased diesel fuel lubricity at concentration of less than 1%. The major objective of this study was to analyze the effectiveness of indigenous non-edible feedstocks such as jatropha (Jatropha curcas) as an additive in petroleum based diesel fuels. Jatropha oil, and its alky esters (methyl and ethyl ester) and oil-ester blends with diesel were tested as an additive to enhance the lubricity of diesel fuels. In case of fuels, the lubricating behavior is associated with boundary film-forming properties. The analysis was carried out by using ASTM 6079-4 test method using High Frequency Reciprocating Rig (HFRR model D1377) as an analytical tool. The coefficient of friction and wear was observed higher for the low lubricity diesel fuel (LLDF) and it decreases with the addition of additive dose of oil, methyl and ethyl ester of jatropha. It may be due to the better lubricating behavior of non-edible based oil and ester compare to LLDF. During the HFRR test 2±0.20 ml of fluid sample under test is placed in reservoir which is maintained at a specified temperature of 60±2 °C. The HFRR test uses a vertically mounted steel ball to apply force to a horizontally mounted stationary steel disk with an applied load (200±1 g). The test ball is oscillated at a fixed frequency (50 ± 1 Hz) with a fixed stroke length (1 ± 0.02 mm) while the disk is fully immersed in the fluid reservoir. The whole test rig was placed in the humidity cabin with transparent enclosure. The test was kept for 75 minutes and the wear scar on the ball was measured by electronic microscope. It is believed that the high concentration of the particular fatty acid in oil and alkyl ester could be responsible for enhancing the lubricity and subsequent lower wear scar.

Full textAbstract:
The fate of transgenic DNA (tDNA) and protein from feed derived from Genetically Modified organisms (GMOs) in animals has been a major issue since their commercialization in 1996. Several studies have investigated the risks of horizontal gene transfer (HGT) of tDNA and protein to bacteria or animal cells/tissues, but some of the reported data are controversial. Previous reports showed that tDNA fragments or proteins derived from GM plants could not be detected in tissues, fluids, or edible products from livestock. Other researchers have shown that there is a possibility of small fragments entering animal tissues, fluids and organs. This motivated us to update our knowledge about these concerns. Therefore, this review aimed to evaluate the probable transfer and accumulation of tDNA/proteins from transgenic feeds in animal samples (ruminant and non-ruminant) by evaluating the available experimental studies published scientifically. This study found that the tDNA/protein is not completely degraded during feed processing and digestion in Gastro-Intestinal Tract (GIT). In large ruminants (cattle), tDNA fragments/proteins were detected in GIT digesta, rumen fluid, and faeces. In small ruminants (goats), traces of tDNA/proteins were detected in GIT digesta, blood, milk, liver, kidney, heart and muscle. In pigs, they were detected in blood, spleen, liver, kidney, and GIT digesta. In poultry, traces were detected in blood, liver and GIT digesta but not in meat and eggs. Notwithstanding some studies that have shown transfer of tDNA/protein fragments in animal samples, we cannot rely on these few studies to give general evidence for transfer into tissues/fluids and organs of farm animals. However, this study clearly shows that transfer is possible. Therefore, intensive and authentic research should be conducted on GM plants before they are approved for commercial use, investigating issues such as the fate of tDNA or proteins and the effects of feeding GM feed to livestock.

Full textAbstract:
The fate of transgenic DNA (tDNA) and protein of feeds from Genetically Modified organisms (GMOs) in animals has been an important topic since their commercialization in 1996. Several studies have investigated about risks of horizontal gene transfer (HGT) of tDNA and proteins to bacteria or animal cells/tissues, however, the reported data is at times controversial. Earlier reports showed that tDNA fragments or protein derived from GM plants have not been detected in tissues, fluids, or edible products of farm animals. Other researchers have come out to demonstrate that there is the possibility of small fragments leaking out into the animal tissues, fluids and organs. This motivated us to update our knowledge about these concerns. Therefore, this review aimed at assessing the likely transfer and accumulation of tDNA/ proteins from transgenic feeds to animal (ruminants and non-ruminants) samples through evaluating the available experimental scientific published studies. This study has found out that the tDNA or protein is not completely degraded during feed processing and digestion in the Gastro-Intestinal Tract (GIT). In large ruminants (Cattle), tDNA fragments/protein have been detected in the GIT digesta, ruminal fluid and feces. In small ruminants (Goats), traces of tDNA/proteins have been detected in the GIT digesta, blood, milk, liver, kidney, heart and muscle. In pigs, they have been detected in blood, spleen, liver kidney and in the GIT digesta. In poultry, traces have been seen in blood, liver and GIT digesta but not in meat and Eggs. Regardless of some studies that have shown the transfer of tDNA/protein fragments to animal samples, we cannot base on these few studies to give a piece of general evidence about their transfer into tissues/fluids and organs of livestock animals. However, this study clearly shows possible transfer, hence intensive and authentic research on GM crops should be done before they are allowed for commercial use, studying issues like the fate of tDNA or proteins and the effect of feeding GM feeds to livestock.

Full textAbstract:
Rapid technological innovation is reshaping the UK food system in many ways. FSA needs to stay abreast of these changes and develop regulatory responses to ensure novel technologies do not compromise food safety and public health. This report presents a rapid evidence assessment of the emerging technologies considered most likely to have a material impact on the UK food system and food safety over the coming decade. Six technology fields were identified and their implications for industry, consumers, food safety and the regulatory framework explored. These fields are: Food Production and Processing (indoor farming, 3D food printing, food side and byproduct use, novel non-thermal processing, and novel pesticides); Novel Sources of Protein, such as insects (for human consumption, and animal feedstock); Synthetic Biology (including lab-grown meat and proteins); Genomics Applications along the value chain (for food safety applications, and personal “nutrigenomics”); Novel Packaging (active, smart, biodegradable, edible, and reusable solutions); and, Digital Technologies in the food sector (supporting analysis, decision making and traceability). The report identifies priority areas for regulatory engagement, and three major areas of emerging technology that are likely to have broad impact across the entire food industry. These areas are synthetic biology, novel food packaging technologies, and digital technologies. FSA will need to take a proactive approach to regulation, based on frequent monitoring and rapid feedback, to manage the challenges these technologies present, and balance increasing technological push and commercial pressures with broader human health and sustainability requirements. It is recommended FSA consider expanding in-house expertise and long-term ties with experts in relevant fields to support policymaking. Recognising the convergence of increasingly sophisticated science and technology applications, alongside wider systemic risks to the environment, human health and society, it is recommended that FSA adopt a complex systems perspective to future food safety regulation, including its wider impact on public health. Finally, the increasing pace of technological

Full textAbstract:
The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the environmental fate and risks related to NP exposure. Carbon-based nanomaterials embedded with metal NPs demonstrate a great potential to serve as catalyst and disinfectors. Hence, synthesis of novel carbon-based nanocomposites and testing them in the environmentally relevant conditions (particularly in the DOM presence) is important for their implementation in water purification. Sorption of DOM on Ag-Ag₂S NPs, CeO₂ NPs and synthesized Ag-Fe₃O₄-carbon nanotubebifunctional composite has been studied. High DOM concentration (50mg/L) decreased the adsorptive and catalytic efficiencies of all synthesized NPs. Recyclable Ag-Fe₃O₄-carbon nanotube composite exhibited excellent catalytic and anti-bacterial action, providing complete reduction of common pollutants and inactivating gram-negative and gram-positive bacteria at environmentally relevant DOM concentrations (5-10 mg/L). Our composite material may be suitable for water purification ranging from natural to the industrial waste effluents. We also examined the role of maize (Zeamays L.)-derived root exudates (a form of DOM) and their components on the aggregation and dissolution of CuONPs in the rhizosphere. Root exudates (RE) significantly inhibited the aggregation of CuONPs regardless of ionic strength and electrolyte type. With RE, the critical coagulation concentration of CuONPs in NaCl shifted from 30 to 125 mM and the value in CaCl₂ shifted from 4 to 20 mM. This inhibition was correlated with molecular weight (MW) of RE fractions. Higher MW fraction (> 10 kDa) reduced the aggregation most. RE also significantly promoted the dissolution of CuONPs and lower MW fraction (< 3 kDa) RE mainly contributed to this process. Also, Cu accumulation in plant root tissues was significantly enhanced by RE. This study provides useful insights into the interactions between RE and CuONPs, which is of significance for the safe use of CuONPs-based antimicrobial products in agricultural production. Wheat root exudates (RE) had high reducing ability to convert Ag+ to nAg under light exposure. Photo-induced reduction of Ag+ to nAg in pristine RE was mainly attributed to the 0-3 kDa fraction. Quantification of the silver species change over time suggested that Cl⁻ played an important role in photoconversion of Ag+ to nAg through the formation and redox cycling of photoreactiveAgCl. Potential electron donors for the photoreduction of Ag+ were identified to be reducing sugars and organic acids of low MW. Meanwhile, the stabilization of the formed particles was controlled by both low (0-3 kDa) and high (>3 kDa) MW molecules. This work provides new information for the formation mechanism of metal nanoparticles mediated by RE, which may further our understanding of the biogeochemical cycling and toxicity of heavy metal ions in agricultural and environmental systems. Copper sulfide nanoparticles (CuSNPs) at 1:1 and 1:4 ratios of Cu and S were synthesized, and their respective antifungal efficacy was evaluated against the pathogenic activity of Gibberellafujikuroi(Bakanae disease) in rice (Oryza sativa). In a 2-d in vitro study, CuS decreased G. fujikuroiColony- Forming Units (CFU) compared to controls. In a greenhouse study, treating with CuSNPs at 50 mg/L at the seed stage significantly decreased disease incidence on rice while the commercial Cu-based pesticide Kocide 3000 had no impact on disease. Foliar-applied CuONPs and CuS (1:1) NPs decreased disease incidence by 30.0 and 32.5%, respectively, which outperformed CuS (1:4) NPs (15%) and Kocide 3000 (12.5%). CuS (1:4) NPs also modulated the shoot salicylic acid (SA) and Jasmonic acid (JA) production to enhance the plant defense mechanisms against G. fujikuroiinfection. These results are useful for improving the delivery efficiency of agrichemicals via nano-enabled strategies while minimizing their environmental impact, and advance our understanding of the defense mechanisms triggered by the NPs presence in plants.
