Resumo: Neste trabalho foi estudada a eliminação dos solventes Percloroetileno (PCE) e Metil Isobutil Cetona (MIBK), em efluentes líquidos de uma planta industrial. A análise pelo período de 4 meses, mostrou valores médios de 17.565 mg/L de PCE e 41.340 mg/L de MIBK. Como tratamento inicial, foi avaliada a eficiência de um POA empregando o reagente de Fenton (H2O2 e Fe). No teste inicial com uma solução sintética a 5000 mg/L, de PCE, foi obtida uma destruição superior a 99% dentro de um período de 6 horas, empregando uma concentração de 1000 mg/L de H2O2 a 60% (m/m), sendo que a reação apresentou uma cinética de 1 ordem (k = 1,94 x 10 s). Para amostras do efluente, foram obtidas eficiências de destruição variáveis com as concentrações iniciais e dosagens aplicadas dos reagentes. Empregando dosagens de H2O2 : Fe (9000 mg/L : 900 mg/L), para uma amostra contendo 10.546 mg/L de PCE e 6.704 mg/L de MIBK, foram obtidas eficiências de remoção superiores a 99,9%, dentro de períodos de 3 horas de tratamento, com cinéticas variáveis entre 1 ordem e 2 ordem. A otimização dos reagentes demonstrou a necessidade de aplicar dosagem correta para obter a destruição total do PCE e MIBK. Com relação ao pH, foi observado que o ajuste para pH 3,0 promoveu um aumento da eficiência da destruição, contra o teste em pH 2,0. Para a maior dosagem de reagentes, observou-se um aumento de 6% na destruição. Paralelamente foi avaliada a eficiência da eliminação do PCE pelo processo de descloração redutiva por Ferro Zero Valente, com remoções de até 89,4%, e a geração do subproduto tricloroetileno. Finalmente, como proposta de trabalho foi estudada a combinação do processo redutivo (Ferro Zero Valente) e oxidativo (Fenton) como uma alternativa para a maximização da eficiência de tratamento e minimização de custos, visto que possibilita a destruição completa tanto do PCE quanto do MIBK dentro do período de 2 horas de tratamento, eliminando ainda a necessidade da adição de ferro.
Abstract: This work is about the removal of Perchloroethylene (PCE) and MethylIsobutyl Ketone (MIBK) in a liquid effluent from an industrial plant. A 4-month analysis has shown average levels of 17,565 mg/L of PCE and 41,340 mg/L of MIBK. Initially, the AOP using Fenton's reagent (H2O2 and Fe) was evaluated. First, a synthetic solution containing 5,000 mg L of PCE was tested and reached elimination greater than 99% within 6 hours of treatment, using a concentration of 1,000 mg/L of H2O2 at 60% (w/w). In this test, a 1 order kinetics (k = 1,94 x 10-4 s-1) was observed. For wastewater samples, using dosages of H2O2 : Fe (9000 mg L:mg L), an elimination destruction above 99,9% was obtained within 3 hours of treatment, for a sample containing 10,546 mg L of PCE and 6,704 mg L of MIBK. Data showed variations between 1st and 2nd order kinetics. Optimization of reactant dosage showed that it is necessary to apply the right dosage to get total elimination of PCE and MIBK. Regarding pH, it was observed that adjustment to pH 3 always gives better results than pH 2. For the greatest dosage of chemicals, an improvement of 6% in the destruction was observed. Simultaneously, a PCE elimination by reductive dechlorination using Zero Valent Iron with removal efficiencies up to 89.4% and generation of trichloroethylene as a by-product was evaluated. Finally, a combination of Oxidative (Fenton) and Reductive (Zero Valent Iron) processes was proposed as an alternative to improve the treatment efficiency and reduce costs. The application of this treatment made it possible to reach complete removal of both contaminants within 2 hours of treatment, besides allowing the elimination of the iron added.

Abstract:

In this work, we have examined the activity and selectivity of new catalysts for the single-stage production of methyl isobutyl ketone (MIBK, 4- methyl-2-pentanone) from acetone (both in liquid and gas phase), using a fixed bed reactor operated in the temperature range between 373 and 473 K. The main reaction pathways for the synthesis of MIBK from acetone are given in Fig.1. The first step is the self condensation of acetone to diacetone alcohol (DAA, 4-hydroxy-4-methyl-2-pentanone); the second step is the dehydration of DAA to mesityl oxide (MO, 4-methyl-3-penten-2-one); the final step is the selective hydrogenation of the carbon–carbon double bond of MO to form MIBK. The most commonly observed side reactions are over-condensations and unselective hydrogenations (also shown in Fig.1). Two types of catalysts were studied: i)Pd supported on MgO-SiO2 mixed oxides with ratio of Mg to Si, synthetized using Ohnishi’s method and ii)Pd supported on alumina doped with 5% or 10% of MgO. The different Mg-Si and Mg-Al catalysts were characterized by different techniques (XRD, BET, SEM, NH3-TPD and CO2-TPD) and tested under different conditions in the condensation of acetone to diacetone alcohol and its dehydration to mesityl oxide to enhance the activity. Palladium was chosen as metal component, and its hydrogenation activity was studied. A low hydrogenation activity negatively affects the acetone conversion and promotes the production of mesityl oxide. Hydrogenation conditions being too severe may favor the unwanted hydrogenation of acetone to 2-propanol and of MIBK to methyl isobutyl carbinol (MIBC, 4-methyl-2-pentanol) but this effect is less detrimental to the MIBK selectivity than an unsufficient hydrogenation activity.

Abstract:

Sweden is one of the heaviest milk consuming countries in the world. The milk- and dairy ‘giant’ Arla, is the largest distributing company of milk- and dairy in Sweden. Since, 1975 Arla began to use the back of their own milk packages as a channel for advertisement, facts, and information. These milk panels have since, been distributed to generations of Swedes. In this thesis I explore the conversations Arla have been mediating through these panels and further how historical and contemporary debates have influenced and altered the conversations conveyed. Inspired by social semiotic theory, I approach the panels to analyse how language and societal debates changes have shaped discourses on the panels, but also how the panel's comments on and reshapes societal debates. The study has been confined study to five years, 1976, 1986, 1996, 2006 and 2016. In order to retrieve and analyse the empirical material I used discourse analysis (or as I prefer to call conversation analysis). The theoretical framework builds on ideas of modernisation using three key theories, Social semiotics, propaganda theory and also theories on nationalism. In the empirical findings of my study, I have distinguished key conversations which I think represent the material as well as societal and contemporary debates. The material shows that Arla on the on hand continue on a tradition of milk marketing in terms of subjects and themes appearing on the panels. On the other hand, Arla is also constantly reinventing themselves in their marketing adjusting to the debates and trends in society.

Why Milk? Facts about Fat in Milk
Milk contains 9 essential nutrients, making it one of the most nutrient-rich beverages that both children and adults can enjoy. We recommend consuming 3 cups per day of fat-free (skim), low-fat (1% or 2%), or equivalent milk products for healthy adults and children 2 years of age and older. We have illustrated the amount of total fat and saturated fat in 1 cup of milk. A delicious and easy recipe for rice pudding using skim milk is also included.

Abstract:

Studies were carried out on two enzymes of bovine milk, N-acetyl-8-D-glucosaminidase (NAGase) and lactate dehydrogenase (LDH), which are indicators of the udder disease mastitis. The main objective of this study was to determine the origins of NAGase and LDH in milk. The approach used was to examine the differences in multiple forms of the enzymes in mammary gland, blood leucocytes and blood plasma by various separation procedures. The molecular weight forms of NAGase in mammary gland and polymorphonuclear leucocytes showed pH-dependent association-dissociation behaviour on gel filtration, but this property was not apparent for blood plasma NAGase. Improved differentiation of NAGases was achieved by ion exchange chromatography at pH 7.0. This method was used to estimate the contributions from the individual sources t6 the total NAGase activity in milk. Mammary gland was the major source of NAGase in normal and mastitic milk. There was a significant contribution from leucocytes in mastitic milk but the contribution from blood plasma was low. The distributions of LDH isoenzymes were examined by polyacrylamide gel electrophoresis. Similar patterns for PMN leucocytes and blood plasma precluded the use of isoenzyme separations for differentiating between LDH enzymes from these two sources. The predominance of the LDH-1 isoenzyme in normal milk indicated that LDH originated from mammary tissue in the healthy udder. In mastitic milk, LDH contributions from all sources were apparent. During these studies, assay procedures for the determination of LDH in milk were developed and a colormetric kit test assessed as a field procedure for testing quarter milks. Positive test results with the kit were unreliable, particularly for freshly-collected milk. Improved diagnostic efficien¢y was achieved using a spectrophotometric assay for LDH. Application of the NAGase and LDH tests to the diagnosis of mastitis in goat's milk showed that changes in milk enzyme levels with minor pathogen infections were insufficient to allow discrimination between uninfected and infected halves.

Abstract:

For the last five years, Sweden has seen a quite remarkable milk war between the traditional Arla serving dairy products and the innovative Oatly offering vegan milk substitutes. The purpose of this thesis was to investigate how consumers’ attitudes are affected by firms’ involvement in brand rivalry, where the conflict between Arla and Oatly served as a case. A conceptual model based on previous research was created to shed light on essential elements that affect consumers’ attitudes. Empirical data was collected through a qualitative content analysis as well as two focus group interviews. Findings resulted in three main insights concerning consumers’ attitudes. Firstly, consumers’ attitudes depend on how the brands decide to leverage and influence consumers’ emotions, where humorous content can smooth over smear campaigns. Secondly, consumers’ attitudes are influenced by their degree of knowledge regarding the conflict, where knowledgeable consumers are often more critical to the content communicated in advertisements. Lastly, consumers’ attitudes are negatively affected if a brand’s core values do not cohere with its engagement in rivalry. This dissertation has contributed to additional insights into brand rivalry initiatives from a consumer perspective. Brands should consider a public conflict more carefully to avoid negative attitudes among consumers.

Abstract:

Infants born prematurely are a vulnerable population with diverse nutritional needs to battle their increased risk of gastrointestinal (GI) diseases. Human milk is considered the 'gold standard' of infant nutrition. Human milk not only provides nutrition for newborn growth, but contains bioactive components which contribute to GI maturation, immune protection and neurological development. Among these bioactive components are extracellular vesicles known as exosomes. Exosomes are double-lipid membrane vesicles containing mRNA, microRNA and proteins, secreted by cells as a form of cell-to-cell communication. Human milk exosomes contain immune-related microRNA and proteins that withstand in vitro simulated human digestion, suggesting that signals are being delivered to the cells residing in the GI tract of a newborn. In premature birth, disruption of GI tract maturation predisposes the infant to increased susceptibility of GI inflammatory diseases. To prevent inflammation, immune tolerance in the GI tract of premature infants should be promoted and I hypothesized that exosomes differ between preterm and term milk, and may contribute to the anti-inflammatory effects of human milk. Human milk exosomes from mothers who gave birth to term or preterm infants were characterized based on size, surface protein markers and total protein. Preterm milk exosomes contained a more diverse protein profile. The effects of milk exosomes on intestinal epithelial cells were observed in an in vitro model using Caco-2/15 cells. Milk exosomes were able to attenuate the inflammatory response induced by heat-killed bacteria as measured by the transcription of pro-inflammatory cytokines.

Abstract:

ABSTRACT Effects of Milk Processing on the Milk Fat Globule Membrane Constituents Xiomara E. Elías-Argote The milk fat globule membrane (MFGM) is avidly studied by many groups of scientists around the world due to its unprecedented nutritional and functional properties; however, limited research has been performed on the effects of milk processing on the chemical changes of the MFGM. Thus, this study highlights the changes that lipids and proteins undergo from the time milk leaves cow’s udders. Cooling (4 °C) was included along with subsequent pasteurization by different traditional thermal processes and cold pasteurization by pulse light ultra violet treatment. Cooling milk to 4 °C had a measureable effect on the MFGM composition, resulting in protein alterations, particularly to butyrophilin and adipophilin. Thermal treatments disturbed the native structures of molecules and increased the adsorption of milk and whey proteins on the globules, especially a-lactalbumin and b-lactoglobulin. As the heat intensity increased, the aggregation of fat globules became more pronounced due to protein interactions. Intrinsic MFGM proteins also varied in relative abundance during the processing steps. The concentrations of polar lipids did not change during processing, with the exception of phosphatidylserine, which decreased during the cooling and thermal treatments. Cold pasteurization (UV treatment) had a minimal effect on fat globules and MFGM proteins. Since the MFGM promises to deliver nutritional effects and more when included in food products, currently HTST pasteurization was shown to be the best method to process milk and obtain MFGM isolates for further supplementation.

Abstract:

Diets of children and adolescents do not meet current national dietary recommendations for food groups. Yet these diets include higher than recommended consumption of added sugars. Food group servings decrease as low-nutrient, energy-dense sugar-sweetened beverages increase. The purpose of this study was to examine whether the consumption of meats, grains, vegetables, and fruits are influenced by consumption of sugar-sweetened milk. Consumption was evaluated in kindergarten, third, and sixth grade students.

Results indicate that consumption of sugar-sweetened milk decreased fruit consumption in all grades, with a significant decrease in sixth grade. All grades had mixed results with meat and vegetable consumption. Grain consumption increased in all grades with sugar-sweetened milk. Further research using sweetened milk with larger groups is needed to document trends in eating patterns that may indicate nutrient dilution through decreased food group consumption.

Abstract:

This thesis follows the trajectory of donated breast milk as it leaves the dyadic mother-child relationship and is reconfigured through a series of transformations as bodily fluid, food, or medicine, depending on its context and the practices and discursive structures that seek to stabilise it as a particular object. Research was conducted between November 2014 and May 2015 in Cape Town, South Africa, including interviews with eleven donating women and eight weeks of participant observation at a level two maternity hospital. Donors use a rhetoric of 'saving babies', the effect of which is to deny the social tie between donor and recipient, or the potential for consubstantiation. Technologies play a crucial role in aiding the milk's transformation as it follows its trajectory through four nodal points (expressing and storage, pasteurisation and testing, packaging, and prescription) from donors' homes into the clinical setting, where it is framed in terms of safety and risk. Care enters into the constellation of relations that the milk ensures in unexpected ways and figures into the ways the milk is distributed in the hospital. Thus, donated breast milk shifts back and forth between being a bodily fluid, food, and medicine as its trajectory takes it through different constellations of saving, motherhood, technologies, care, safety, risk and medical authority. Different techniques foreground particular properties of the milk, as ultimately a set of moral decisions converges around saving, securing and sustaining life, materialising relationships and forming the milk form one entity into another and back again.

Abstract:

The overall aim of this thesis was to determine the feasibility of breeding for improved milk quality and in particular protein fractions, free amino acids (FAA) and milk colour. To breed for a characteristic such as milk quality it must be; (i) economically or socially important (ii) exhibit genetic variation (i.e be heritable), and (iii) be measurable or genetically correlated with a measurable trait. Gold standard data was determined from 715 milk samples. Spectral data used consisted of ~ 95,000 milk samples from seven research herds and ~ 40,000 milk samples (morning and evening milk samples combined) from 69 commercial herds. The greatest correlation coefficients of external validation obtained for protein fractions, FAA and milk colour were 0.74 (total casein), 0.75 (glycine) and 0.72 (yellowness), respectively. Milk protein fractions and FAA change across calendar months of the year, stage of lactation and parity. A peak in the concentration of all casein fractions was evident in the months of August, September and October. The concentration of glutamic acid was greatest during the months of February, March, April and June when adjusted for milk yield. Changes in individual milk protein fractions and FAA across calendar months of the year and across stages of lactation could provide useful input parameters for decision support tools in the management of product portfolios by processors over time. Heritability of the predicted protein fractions and FAA ranged from 0.04 (beta casein) to 0.61 (total lactoglobulin) and from 0.05 (aspartic acid) to 0.58 (serine), respectively. The coefficient of genetic variation of gold standard protein fractions and FAA ranged from 3.01 (alpha lactalbumin) to 22.98 (total lactoglobulin) and from 1.01 (glutamic acid) to 25.65 (serine), respectively. Milk colour traits were low to moderately heritable ranging from 0.29 (lightness) to 0.35 (yellowness), respectively. The coefficient of genetic variation of milk colour ranged from 0.37 (lightness) to 1.72 (greeness), respectively. Results from this thesis clearly show that some protein fractions, some FAA and milk colour are predictable from MIRS and these predictions exhibit genetic variation and thus breeding for improved milk quality is feasible. The outcome of this thesis is primarily that the prediction of these traits by MIRS could benefit the dairy breeding industry worldwide through genetic selection of animals with higher quality milk and allowing for the more accurate selection of milk for human consumption, infant milk formula, and cheese production. The generated predictions could also be useful for herd and processor management strategies.
L’obiettivo generale della presente tesi è stato quello di determinare la possibilità di poter migliorare, tramite programmi di selezione genetica, la qualità del latte e in particolare le frazioni proteiche, gli amino acidi liberi (FAA) e il colore. Per essere migliorato geneticamente un carattere (incluso la qualità del latte) deve: i) essere di importanza, sia essa economica o anche sociale; ii) esibire variabilità genetica, ossia deve essere ereditabile; iii) essere misurabile o correlato geneticamente con un carattere che sia misurabile. Le analisi di riferimento per i suddetti parametri di qualità del latte sono state determinate su 715 campioni di latte. Il dataset di spettri includeva misurazioni infrarosse su circa 95 000 campioni di latte raccolti in sette aziende sperimentali, mentre altri circa 40 000 spettri (determinati su campioni di latte di entrambe le mungiture giornaliere) erano provenienti da 69 aziende commerciali. I più alti coefficienti di correlazione, in validazione esterna, ottenuti per frazioni proteiche, FAA e colore del latte sono stati rispettivamente di 0.74 (caseine totali), 0.74 (glicina) e 0.72 (indice del giallo). Le frazioni proteiche del latte e gli FFA hanno dimostrato variazioni tra mesi dell’anno, tra stadi di lattazione e tra ordini di parto. Un picco nella concentrazione di tutte le frazioni caseiniche è stato evidente nei mesi di Agosto, Settembre ed Ottobre. La concentrazione di acido glutammico è stata maggiore nei mesi di Febbraio, Marzo, Aprile e Giugno a parità di produzione di latte giornaliera. Le variazioni di frazioni proteiche e FAA attraverso mesi dell’anno e stadi di lattazione possono fornire all’industria di trasformazione lattiero-casearia uno strumento per gestire il proprio portafoglio prodotti lungo uno specifico periodo produttivo. I valori di ereditabilità dei fenotipi predetti hanno avuto un minimo di 0.04 (beta caseina) ed un massimo di 0.61 (lattoglobulina totale) per le frazioni proteiche, mentre per quanto riguarda gli FAA hanno variato tra 0.05 (acido aspartico) e 0.58 (serina). Il coefficiente di variazione genetico per frazioni proteiche misurate ha variato tra 3.01% (alfa lattoalbumina) e 22.98% (lattoglobulina totale), mentre per gli FFA misurati ha variato tra 1.01% (acido glutammico) e 25.65% (serina). Il caratteri di colore del latte hanno dimostrato una ereditabilità medio-bassa, con un range compreso tra 0.29 (luminosità) e 0.35 (indice del giallo). Il coefficiente di variazione genetico del colore del latte ha avuto un minimo di 0.37% (luminosità) ad un massimo di 6.68% (indice del giallo). I risultati della presente tesi dimostrano chiaramente che alcune frazioni proteiche, alcuni FAA e il colore del latte sono di possibile predizione attraverso la tecnologia nel medio-infrarosso, e tali fenotipi predetti hanno variabilità genetica il che implica che programmi di selezione per migliorare la qualità del latte sono possibili. I risultati principali di questa tesi sono che le predizioni di questi caratteri usando la spettroscopia nel medio infrarosso possono rappresentare un beneficio per gli allevatori di vacche da latte attraverso la selezione genetica di animali con una migliore qualità del latte. Inoltre, questa tesi offre delle opportunità per una selezione più accurata del latte destinato al consumo umano, alla produzione di latte per neonati e alla produzione di formaggio. Inoltre, tali predizioni possono rappresentare dlle opportunità per il management aziendale e industriale.

If drinking milk or eating foods made from milk, like cheese, yogurt, or ice cream, upsets your stomach then you may be lactose intolerant. Some people make too little lactase, so lactose from milk is not absorbed. There are alternatives to obtain the daily calcium if you are lactose intolerant.

Abstract:

Mastitis is the most common and economically the most important disease of dairy cattle throughout the world. However in Australia, there is an absence of scientifically based data using herd bulk milk supplies. Animals from each of two farms were divided into three groups based on milk sec and NAGase contents. Milk collected from these animals over a two year period was used to study the influence of sec (as a measure of mastitic infection) on milk composition and milk product quality. Milk compositional studies indicated that log sec was positively correlated to the NCN, BSA, chloride, sodium, NAGase (P<0.005), K-casein, {-casein (P<0.01) and IgG (P<0.05) contents, the pH level (P<0.005) and the NCN:total nitrogen, chloride:lactose and sodium:potassium ratios (P<0.005). Log sec was negatively correlated to the SNF, lactose (P<0.005), ft-casein, ~-lactalbumin, ~-lactoglobulin, soluble calcium (P<0.01), total solids, casein and total calcium (P<0.005) contents and the casein:total protein ratio (P<0.005). When milk samples were grouped into sec categories, results indicated that samples with an sec of greater than 500 000 cells/ml were compositionally inferior to samples with an sec of less than 500 000 cells/ml. Pasteurised milk studies indicated that the organoleptic quality of samples with an sec of less than 1 000 000 cells/ml was generally superior to the organoleptic quality of samples with an sec greater than 1 000 000 cells/ml. Skim milk yoghurt studies indicated that the organoleptic quality of both unsweetened and sweetened yoghurts manufactured from milk with an sec of less than 250 000 cells/ml were superior when compared to yoghurtsmanufactured from milk with an sec of greater than 250 000 cells/ml. The rennet coagulating time of milk was significantly longer when the sec became greater than 500 000 cells/ml. Cheddar cheese manufactured from milk with an sec of greater than 500 000 cells/ml had higher moisture and MFFS and lower fat, FDM and pH. Increased losses of fines (P<0.05) into the whey resulted in lower cheese yields (P<0.10). Log sec was negatively correlated to both cheese flavour and body and texture grades (P<0.10) at six months of age. Cheeses became softer, less springy (P<0.10) and cohesive, more adhesive (P<0.05), and less stringy (P<0.05) as the sec of the milk increased. Skim milk powder studies indicated that the effects of elevated sec on skim milk powder properties and organoleptic quality were minimal. From the results obtained in this study it is suggested that sec threshold values of 1 000 000 and 500 000 cells/ml should be used for market milk and manufacture milk supplies respectively.

Abstract:

Residual value is defined as the price for which a used piece of equipment can be sold in the market at a particular time. It is an important element of the owning costs of equipment and needs to be estimated by equipment managers for making investment decisions. The purpose of this study is to gain insights into the residual value of selected groups of heavy construction equipment and to develop a mathematical model for its prediction. Auction sales data were collected from two online databases. Manufacturer publications and an online source provided size parameters and manufacturers suggested retail prices matching the auction records. Macroeconomic indicator values were collected from a variety of sources, including government agencies. The data were brought into the same electronic format and were matched by model name and calendar date, respectively. Data from auctions in the U.S. and in Canada were considered for this study. Equipment from four principal manufacturers of up to 15 years of age at the time of sale was included. A total of 35,542 entries were grouped into 11 different equipment types and 28 categories by size as measured by horse power, standard operating weight, or bucket volume. Equipment types considered were track and wheel excavators, wheel and track loaders, backhoe loaders, integrated toolcarriers, rigid frame and articulated trucks, track dozers, motor graders, and wheel tractor scrapers. Multiple linear regression analyses of the 28 datasets were carried out after outliers had been deleted. Explanatory variables for the regression model were age in years, the indicator variables manufacturer, condition rating, and geographic region, and selected macroeconomic indicators. The response variable was residual value percent, defined as auction price divided by manufacturers suggested retail price. Different first, second, and third-order polynomial models and exponential and logarithmic models of age were examined. A second-order polynomial was selected from these functional forms based on the adjusted coefficient of determination. Coefficients for the 28 models and related statistics were tabulated. A spreadsheet tool incorporating the final regression model and its coefficients was developed. It allows performing the residual value prediction in an interactive and intuitive manner.

Abstract:

Premature newborns’ medical need for donor human milk surpasses the supply and the demand for it continues to increase. Lactating mothers with a surplus can help fill the gap and give fragile infants a better chance to grow by donating breast milk. This thesis project examines challenges in the human milk donation process and observes general milk donation operations. It seeks to answer what kind of tools and support are needed to streamline the human milk donation process for lactating mothers who voluntarily donate their extra milk supply. Looking closely at information and communication technologies, the project notes design implications for the development of donor-supported digital tools. Through a user-centered design approach, qualitative interview strategies, and feedback from a milk bank, mockups of a digital waiting room were created to provide informational and social support for donor mothers.

Abstract:

Bovine plasmin activity was measured on H-D-valyl-L-leucyl-L-lysyl-4-nitroanilide by following absorbance changes at 405 nm. Steady-state kinetic parameters Vmax, Km, KI, and KI' were estimated. Bovine plasmin is competitively inhibited by casein and has a Kcat of .0158 ΔA405/min/nM, Km of .107 mM substrate, and KI of .86 mg/ml casein. Bovine plasmin can be measured directly in bovine milk without interference from casein. A total of 380 milk samples from nineteen Holstein (one herd) and nineteen Jersey (one herd) cows was collected monthly during one lactation period. Samples from each cow were analyzed for fat, protein, plasmin activity, plasminogen, pH, SCC, clotting time, curd firming rate, and final curd firmness. Three age groups form each breed/herd were chosen; first, third, and fourth and later lactations. Plasmin activity in milk was most affected by lactation number, with milk from fourth- and later-lactation cows having higher activity than milk from first- or third- lactation cows. Plasmin activity in milk increased during lactation but was not affected by breed/herd, pH, protein, or fat. Plasminogen averaged 5.4 times the plasmin activity in milk and increased during the first five months of lactation. Plasmin activity was higher in milk collected ruing summer and fall but plasminogen was higher in milk collected during fall and winter. Percentage of the total (plasmin+plasminogen) enzyme activated to plasmin increased in late-lactation milk and in milk from fourth- and later-lactation cows. Plasmin activity did not affect any milk clotting parameters in this study. Increased protein in milk resulted in shorter clotting times. When statistically adjusted for protein content, clotting time was longer in milk from the Holstein herd compared to the Jersey herd. Curd firming rate was increased in milk with higher protein and fat. Milk samples collected in the fall had faster firming rates than milk from other seasons. Firming rates remained constant during lactation but increased with higher protein and fat content. Jersey herd milk produced firmer curd than Holstein herd milk and milk collected in the fall had firmer curd than during the other seasons.

Abstract:

Thesis (BTech (Food Technology))--Cape Technikon, 1999.
The Dairy industry, one of the larger food industries in South Africa processes probably the most perishable and possibly the most regulated foodstuff, namely mille The unique combination of vitamins, proteins, carbohydrates, lipids, moisture and near neutral pH, offers a suitable environment for the proliferation of microbes. Milk is therefore highly susceptible to microbiological activity resulting in the irreversible spoilage of this food (Frazier & Westhoff, 1988). The coliform group of organisms comprises all aerobic and anaerobic, gram-negative, non-spore-forming rods that are able to ferment lactose with the production of acid and gas at 32°C within 48 hours (Richardson, 1985). The primary purpose of the coliform detection test is to measure the quality of the practices used to minimise bacterial contamination of processed dairy products (Richardson, 1985). IDF Standard 132A: (1991) defines psychrotrophic organisms as organisms forming countable colonies when incubated aerobically at 6.5°C for 10 days under the conditions specified in IDF standard 101A. Shelf-life tests conducted in the fresh milk laboratory of a processing plant, revealed significant growth of coliforms in samples stored at 5°C. Luch, (1985) reported that other contaminating psychrotrophs together with the coliforms reduce the shelf-life of the milk when the storage temperature thereof is above 10°C.

Abstract:

This report presents the primary development process of an innovative milk foamer. The project is structured as the primary development process that is used at Electrolux Floor Care and Small Appliances AB, Global Primary Development and Innovation department in Stockholm, Sweden. The aim was to develop a milk foamer with innovative solutions to provide Electrolux with a unique product. The objective was to create a product that highly meets customer requirements and in the same time is feasible to develop into a selling product. All the aspects regarding a consumer product had to be considered. To create innovative solutions thorough investigations of the physics behind foaming and foam are studied and documented. The difference in foam quality when using different ways of foaming is documented and possible explanations is discussed. The primary development process range from pre-study and customer research to designing prototypes and verifications. Most of the report deals with standalone solutions but there is also a part of the report that deals with integrated solutions and cooperating solutions that would be used together with espresso machines. The result is a variety of concepts and four fully working standalone prototypes. Two prototypes are further developed and are highly interesting to Electrolux.

Abstract:

Milk secretion is controlled locally, within the mammary, gland, by milk removal. This control is believed to be mediated through feedback inhibition by milk constituents. The aim of this study was to investigate the effects of milk-borne peptides, implicated in the local control ofmilk secretion, on protein secretion in bovine mammosphere culture. These peptides, tenned A, Band C, had previously been shown in mammary acini cultures to acutely inhibit the secretion of milk proteins. To this end, a bovine mammosphere culture system was developed whereby bovine mammary epithelial cells cultured on EHS matrix were stimulated to express milk protein genes and secrete the major milk proteins casein, (3-lactoglobulin and lactoferrin. Additionally, the recent claim that the phosphopeptide (3casein 1-28 (Silanikove et ai, 2000) was capable of controlling milk secretion was investigated in'mouse mammary acini and bovine mammosphere culture. The secretory perfonnance of the bovine mammosphere system was validated by western blot measurement ofcasein, (3-lactoglobulin and lactoferrin in conditioned culture medium, . and mammosphere fonnation was investigated by SEM and cryosectioning of cultured cell aggregates. Experiments investigating the effects ofthe peptides tested all three peptides in combination (triple peptide treatment), the peptide pair AC, peptide B and (3-casein 1-28. Peptide effects were assessed by measuring 3H-Ieucine incorporation into TCA precipitable protein following 2 and 4 days oftreatment. Additionally, the effect 'ofthe triple peptide on (3-casein and lactoferrin mRNA abundance, and on the secretion of the major bovine milk proteins casein, (3-lactoglobulin and lactoferrin, was measured by real time RT-PCR and western blotting respectively. (3-casein and lactoferrin mRNA abundance was significantly reduced in bovine mammosphere culture following triple peptide treatment for two days. At concentrations of 1 pM and 10 pM of all three test peptides, triple peptide treatment caused 35 % and 47 % reductions, respectively, in (3-casein mRNA levels, and 21 % and 35 % reductions respectively in lactoferrin mRNA levels. This was not reflected in changes in milk protein secretion, with no significant effect observed on total protein secretion or individual milk protein secretion after two days of treatment. This may be a consequence of the insensitivity ofthe blotting technique used, resulting in trends in the data for the three milk proteins being rendered insignificant due to large variations between replicates. On the other hand, triple peptide treatment for two days significantly increased mRNA levels of the purported housekeeping gene GAPDH, which rose by 75 % when treated with 10 JlM of the triple peptide. These effects may have been associat~d with aggregation of the three peptide~in culture: incubation of peptides A, Band C together at 37Ã‚Â°C for 25 h resulted in the formation of apeptide multimer, which was detected by gel exclusion fast protein liquid chromatography. Although no definitive role for these peptides in the local control of milk secretion was established, the results suggest that the peptides may control milk secretion by reducing milk protein gene expression. Furthermore, GAPDH has recently been implicated in the control of ER - Golgi transport in the early secretory pathway in NRK cells. This role offers a potential explanation for the increase in GAPDH mRNA induced by peptide treatment, and suggests that these peptides may effect milk secretion by blocking GAPDH mediated retrograde vesicular transport. The data obtained in this study has extended information on factors which appear able to control mammary function locally, and together with our increasing understanding of the control of secretory pathways, has provided scope for further investigation of the mechanism by which milk-borne factors control milk secretion.
