Athletes often consume functional beverages in order to improve performance and reduce oxidative stress caused by high-intensity exercise. The present study aimed to evaluate the antioxidant and antibacterial properties of a functional sports beverage formulation. The beverage’s antioxidant effects were assessed on human mesenchymal stem cells (MSCs) by determining thiobarbituric acid reactive substances (TBARS; TBARS levels decreased significantly by 52.67% at 2.0 mg/mL), total antioxidant capacity (TAC; TAC levels increased significantly by 80.82% at 2.0 mg/mL) and reduced glutathione (GSH; GSH levels increased significantly by 24.13% at 2.0 mg/mL) levels. Furthermore, the beverage underwent simulated digestion following the INFOGEST protocol to assess its oxidative stability. The analysis of the total phenolic content (TPC) using the Folin–Ciocalteu assay revealed that the beverage contained a TPC of 7.58 ± 0.066 mg GAE/mL, while the phenolics identified by HPLC were catechin (2.149 mg/mL), epicatechin (0.024 mg/mL), protocatechuic acid (0.012 mg/mL), luteolin 7-glucoside (0.001 mg/mL), and kaempferol-3-O-β-rutinoside (0.001 mg/mL). The beverage’s TPC was strongly correlated with TAC (R2 = 896). Moreover, the beverage showcased inhibitory and bacteriostatic effects against Staphylococcus aureus and Pseudomonas aeruginosa. Lastly, the sensory acceptance test demonstrated that the functional sports beverage was well accepted by the assessors.

In Croatia, the production of non-alcoholic wort-based beverages is in its initial stages. The main goal of this research was to produce wort that could be then used in the production of a wort-based beverage with the addition of chokeberry (Aronia melanocarpa) juice. Sensory characteristics and consumer acceptance was also analyzed. Worts were prepared by the standard mashing process, using Munich and pale ale malt. Chokeberry juice was added to the cooled worts. For the purpose of this research, two versions of wort with different concentrations of chokeberry juice (10%, 20%, 30%) were formulated, and all of the beverages were subjected to sensory analysis. Sensory analysis showed that wort with the addition of 30% chokeberry juice was the most accepted. This concentration of chokeberry juice gave the beverage a pleasant taste, but needed some improvement. To address this, mint essential oil was added to the mixture and carbonation using gaseous CO2 was conducted. This beverage received better acceptance when carbonated and mixed with mint essential oil. In addition to the sensory analysis, the polyphenol content of the chosen beverage was also analyzed, along with its nutritional value. Polyphenol content was 2621.47 mg/L and antioxidative activity was 2.28 mmol Trolox/L. The energy value was determined to be 57 kcal. However, in order to optimize the production of this wort-based beverage, further research should be conducted.

Aim: Soy whey is a byproduct of tofu production and is being discarded after tofu preparation. However, soy whey is a rich source of phytochemicals, minerals, and protein. The present study was conducted to utilize soy whey for the development of nutraceutical-rich orange juice beverages. Methods: The soy whey and orange juice were produced and beverage samples were developed from them. The samples were evaluated for physicochemical, rheological, antioxidant, and sensory properties to evaluate the optimum percentage of soy whey that can be utilized for beverage development. Results: The protein content increased from 0.45% to 1.65% with an increase in soy whey from 0% to 50%. The pH of the beverage samples was in the range of 4.27–4.77 with the total soluble solids (TSSs) of 5.75–6.0 for various beverage samples. The lightness (L*), redness (+a*), and yellowness (+b*) of beverage samples range between 31.57–49.04, 1.21–0.54, and 25.37–39.63 respectively. The vitamin C content of the beverage samples was 56.30 mg/L, 52.75 mg/L, 36.97 mg/L, 26.35 mg/L, and 22.87 mg/L for A, B, C, D, and E beverages respectively. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), reducing power ranges of beverage samples range between 91.2–96.23%, 0.521–0.994%, and 0.204–0.859% respectively, and total phenolic content (TPC) ranges between 112 mg gallic acid equivalents (GAE)/100 mL and 181 mg GAE/100 mL of beverage samples. The beverage samples presented a shear thinning property with a flow index (n) ranging between 0.2371–0.8214. The consistency coefficient of the beverage samples ranges between 0.0405 Pa∙Sn and 0.0041 Pa∙Sn. The control, 20%, and 30% soy whey-containing beverage samples showed higher sensory properties. Conclusions: The beverage samples with 0%, 20%, and 30% showed improved DPPH and FRAP percent activity and higher overall acceptability compared to 40% and 50% soy whey-containing beverage samples.

Blueberries are rich in polyphenols, anthocyanins, and proanthocyanidins; however, they are expensive. In contrast, strawberries have a lower cost and are rich in ellagitannins. Therefore, a strawberry–blueberry blend decoction could produce a low-cost beverage with a rich and diverse phytochemical profile. In this study, we developed three berry-based beverages: blend strawberry–blueberry (SBB), strawberry (SB), and blueberry (BB). The polyphenol profile of the beverages was characterized by UPLC-ESI-Q-ToF MSE, an acceptability test was carried out with potential consumers, and a stability analysis was performed under commercial storage conditions (4, 25, and 34 °C). The SBB exhibited a good sensorial preference (score of 81.3) and showed high contents and a diverse composition of anthocyanins and proanthocyanidins, which were up to 3.0- and 1.2-fold higher compared to the SB, respectively. Regarding the storage stability, the SBB showed better retention of lightness (97.9%) and red color (66.7%) at the end of the storage under refrigerated conditions (4 °C) compared to the SB. Therefore, these results demonstrate that using blended berry fruits leads to the creation of a functional beverage that has higher nutraceutical potential than single-berry-based beverages.

Consumers see whey beverages as inferior products to yogurts, especially regarding texture and viscosity. The aim of this work was to evaluate consumers' perception of the differences between yogurt and fermented whey beverage using word association and check-all-that-apply (Cata). Untrained assessors (n = 100) evaluated samples of three commercial brands of liquid or stirred yogurt and whey beverage, of strawberry flavor. Chemical and physical parameters (pH, acidity, total solids, color, texture and syneresis) were determined to assist in the interpretation of the results. The study showed that physical and chemical characteristics were inherent to each product, with no homogeneity within each category. The texture was the parameter that most influenced consumer responses. Yogurt is not necessarily always more viscous than fermented whey beverages. In addition, sensory acceptability was not linked to the product category, pointing to the importance of the individual characteristics. Word association and Cata were able to access the main differences between both products and brought important qualitative and quantitative information regarding consumers’ opinions. This study contributed to demystifying the perception that fermented whey beverages have attributes considered inferior, such as lower viscosity and greater syneresis when compared to yogurts. It was found that there is a demand for information about yogurt and fermented whey beverages, which can influence consumers' opinions at the time of purchase.

Arbutus unedo spirit is a valuable product in Mediterranean countries. This spirit is usually marketed in Portugal without wood ageing. This work aims to characterize the ageing effect on the Arbutus unedo spirit, for three and six months with oak wood (Quercus robur L.) submitted to different toasting levels, based on its chemical composition and its sensory properties. For this purpose, several parameters were analysed: acidity, pH, dry extract, and volatile compounds (methanol, acetaldehyde, ethyl acetate and fusel alcohols). The volatile compounds were identified by GC-MS and quantified by GC-FID. Sensory analysis was performed by a trained panel, who have profiled this beverage, as well as the changes acquired during ageing. Spectroscopic techniques, namely FTIR–ATR, were applied to discriminate the different beverages produced. The results highlighted an increase in Arbutus unedo spirit’s quality with the wood contact, mainly based on the sensory attributes. Additionally, they showed that the best beverages were produced using oak wood with medium toasting levels during three months of ageing.

Amazonian fruits are excellent sources of bioactive compounds and can be used in beverages to improve the nutritional and sensorial characteristics. The present study aimed to develop a blend of murici (Byrsonima Crassifolia (L.) Kunth) and taperebá (Spondias Mombin L.) through experimental design and investigating the nutritional and sensorial characteristics of fruits and beverages. The murici was highlighted as higher vitamin C content (58.88 mg · 100 g−1) compared to taperebá (25.93 mg · 100 g−1). The murici and taperebá are good sources of total phenolic compounds (taperebá 1304.15 ± 19.14 mgGAE · 100 g−1 and the murici of 307.52 ± 19.73 mg GAE · 100 g−1) and flavonoids (174.87 ± 1.76 μgQE/g and 129.46 ± 10.68 μgQE/g, murici and taperebá, respectively), when compared to other Brazilian fruits. The antioxidant capacity in different methods revealed that the taperebá had a higher average in the results, only in the ORAC method and did not present a significant difference (p > 0.05) in relation to the murici. The beverage development was performed using experimental design 23, showed through sensory analysis and surface response methodology that murici and high sugar content (between 12.5 and 14.2% of sugar) influenced in sensory acceptance. Our findings indicate that beverages with improved nutrition and a sensory acceptance can be prepared using taperebá and murici fruits.

The chemical composition of alcoholic beverages plays a crucial role in their flavor, and the interaction with the chemistry of the mouth, particularly saliva, further shapes the sensory experience. Saliva's pH and enzyme activity can affect the chemical balance of the drink, and therefore, the taste and aroma perceived by the taster. This study examined the influence of saliva on the pH and α-amylase activity of alcoholic beverages, through a potentiometer and enzymatic kits respectively, and how this affected their sensory profile, through the performance of a Descriptive Analysis (DA) sensory test. The results showed that the pH values of the drinks were altered after contact with saliva, with brandies showing an increase in pH and wines showing a decrease. Additionally, the α-amylase activity was found to be influenced by the presence of acids, ethanol, and tannins in the drink. These observations suggest that the chemical composition of the drink and the saliva can impact the sensory experience. Further studies can help to elucidate the mechanisms underlying this interaction and how it varies across different types of beverages and individuals through sensitive enzyme kits.

Since certain constituents are not naturally present in pure fruit juices, incorporating herbal extracts can provide specific sensory properties to the beverages and improve their biopotential. In our previous research, it was found that sage (Salvia officinalis L.), wild thyme (Thymus serpyllum L.), and combinations of their extracts had the highest total phenolic content and a unique composition of volatile compounds, which can contribute to the aromatic and antioxidant qualities of functional products. Therefore, this research aimed to investigate the potential of sage and wild thyme extracts, as well as their mixture (wild thyme:sage at 3:1, v/v), to enrich fruit juices (apple, pineapple, and orange). Obtained beverages were evaluated for sensory properties as well as phenolic and headspace composition (UPLC-MS/MS and HS-SPME/GC-MS analysis) and antioxidant capacity (ORAC assay). The incorporation of wild thyme extract in pineapple juice provided the most harmonious flavor and the highest content of volatile compounds (on PDMS/DVB fiber). The orange juice formulations were the most enriched with phenolic and volatile compounds (on DVB/CAR/PDMS fibers). The highest antioxidant capacity was observed in the formulation with orange juice and sage extract (22,925.39 ± 358.43 µM TE). This study demonstrated that enriching fruit juices with sage and wild thyme extracts could create functional beverages with improved sensory and health-promoting properties, providing valuable insights for the food and beverage industry to meet the growing demand of health-conscious consumers for natural and functional products.

ENGLISH ABSTRACT: Nectar formulations containing red-fleshed plum pulp and varying amounts of red-fleshed plum skin extract were developed. Red-fleshed plum nectar formulations containing 0, 8, 16, 24, and 32% skin extract were benchmarked against twenty-two commercial beverages containing red, violet and blue fruits. The total soluble solid content, pH, titratable acidity, colour, total polyphenolic, individual polyphenolic, total anthocyanin, and ascorbic acid contents, as well as antioxidant activity (oxygen radical antioxidant capacity (ORAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and ferric reducing/antioxidant power (FRAP)) of the commercial beverages and plum formulations were determined. The plum nectar formulations had similar or higher total polyphenolic content, antioxidant activity, and colour values than the average for the commercial beverages. The individual polyphenolic compounds analysed in the nectar formulations were cyanidin-3-glucoside, cyanidin-3- rutinoside, quercetin-3-glucoside, quercetin-3-rutinoside, quercetin-3-xyloside, and neochlorogenic acid. Increasing polyphenolic content and antioxidant activity was observed with an increase in skin extract content of the formulations. The sensory attributes of the formulations were plum and plantlike aroma, plum and plantlike flavour, sweetness, acidity, and astringency. Increases in plantlike aroma and flavour, acidity, and astringency in conjunction with decreases in plum aroma, plum flavour, and sweetness extract were observed with an increase in skin extract. Consumer analysis indicated that all formulations were acceptable. The 0 and 16% skin extract formulations were most preferred, while the 32% skin extract formulation was least preferred. A shelf-life study was conducted in two phases. In Phase 1, the 0, 16 and 24% skin extract formulations were stored at 0 and 5°C (analysis time points: before pasteurisation, after pasteurisation (week 0), and after 1, 2, 4, 6, 8, 12, 16, 18, 20, and 24 weeks of storage). Chemical analyses conducted included colour, total polyphenolic, individual polyphenolic compound, and total anthocyanin contents, and antioxidant activity (DPPH• scavenging activity). Results from Phase 1 indicated close associations between the 16 and 24% skin extract formulations, and between these formulations and all chemical attributes. Regression analysis of results indicated significant (P 0.05) decreases in red colour, total anthocyanins, cyanidin-3-glucoside, cyanidin-3- rutinoside, DPPH• scavenging activity, total polyphenolic content, quercetin-3-rutinoside, and quercetin- 3-xyloside for formulations stored at 0°C. The total and red colour, total anthocyanins, cyanidin-3- glucoside, and cyanidin-3-rutinoside in formulations stored at 5°C showed similar results. During Phase 2 of the shelf life study, sensory analysis was conducted on the 0 and 24% skin extract formulations stored at 5°C (preparation time points: 0, 1, 2, and 3 months). Sensory attributes, including plum, plantlike, and raisin flavour, sweetness, acidity, and astringency, were stable during storage. Chemical results from Phase 2 were similar to those of Phase 1. The chemical and sensory stability of formulations after 24 weeks of storage in Phase 1 and Phase 2 indicated that, with the exception of the anthocyanin degradation, the formulations could be beneficial to juice industries. Thus, red-fleshed plum nectars have the potential to compete with high-antioxidant fruit beverages.
AFRIKAANSE OPSOMMING: Nektarformulasies wat rooivleis pruimpulp en varieërende hoeveelhede rooivleis pruimskilekstrak bevat, is ontwikkel en ondersoek. Rooivleis pruimnektarformulasies wat 0, 8, 16, 24, en 32% skilekstrak bevat, is vergelyk met twee-en-twintig kommersiële drankies wat rooi, violet en blou vrugte bevat. Die totale oplosbare vastestof, totale polifenoliese, individuele polifenoliese, totale antosianien- en askorbiensuur inhoude, sowel as die pH, titreerbare suurheid, kleur, antioksidant aktiwiteit (suurstofradikale antioksidantkapasiteit (ORAC), 2,2-difeniel-1-pikrielhidrasiel (DPPH) radikaal blussingsaktiwiteit, en ysterreduserende/antikoksidantkrag (FRAP)) van die kommersiële drankies en pruimnektarformulasies, is bepaal. Die pruimnektarformulasies het soortgelyke of hoër totale polifenoliese inhoud, antioksidantaktiwiteit, en kleurwaardes gehad in vergelyking met die gemiddelde vir die kommersiële drankies. Die individuele polifenoliese verbindings wat in die nektarformulasies geanaliseer is, was sianidien-3-glukosied, sianidien-3-rutinosied, kwersetien-3-glukosied, kwersetien-3-rutinosied, kwersetien-3-xylosied, en neochlorogeniese suur. ‘n Toenames in die kleurwaardes, polifenoliese inhoud, en antioksidantaktiwiteit is waargeneem met ‘n toename in skilekstrak is in die formulasies. Die sensoriese eienskappe van die formulasies was pruim- en plantagtige aroma, pruim- en plantagtige geur, soetheid, suurheid, en frankheid. Toenames in plantagtige aroma en geur, suurheid en frankheid, sowel as ‘n afname in pruimaroma, pruimgeur, en -soetheid, is met ‘n toename in skilekstrak waargeneem. Verbruikersanalise het aangedui dat al die formulasies aanvaarbaar was. Die 0 en 16% skilekstrakformulasies was die mees aanvaarbaarste, terwyl die 32% skilekstrakformulasie die minste aanvaarbaar geag is. ‘n Rakleeftydstudie is in twee fases gedoen. In Fase 1 is die 0, 16, en 24% skilekstrakformulasies by 0 en 5°C gestoor (analiseringstydpunte: voor pasturisasie, na pasturisasie (week 0), en na 1, 2, 4, 6, 8, 12, 16, 18, 20, en 24 weke van berging). Chemiese analise wat gedoen is, sluit totale polifenoliese, individuele polifenoliese verbinding, en totale antosianien inhoude, sowel as kleur en antioksidantaktiwiteit (DPPH• blussingsaktiwiteit) in. Resultate van Fase 1 het ‘n nou verband tussen die 16 en 24% skilekstrakformulasies, sowel as tussen hierdie formulasies en hul chemiese kenmerke aangedui. Regressie-analise van resultate het betekenisvolle (P 0.05) afnames geïllustreer in rooi kleurwaardes, DPPH• blussingsaktiwiteit, sowel as totale antosianiene, sianidien-3-glukosied, sianidien-3-rutinosied, totale polifenoliese, kwersetien-3-rutinosied, en kwersetien-3-xylosied inhoude van die formulasies wat by 0°C gestoor is. Die totale kleur-, rooi kleurwaardes, sowel as totale antosianien, sianidien-3-glukosied, en sianidien-3-rutinosied in die formulasies wat by 5°C gestoor is, het soortgelyke resultate gegee. Gedurend Fase 2 van die rakleeftydstudie is sensoriese analise op die 0 en 24% skilekstrakformulasies wat by 5°C gestoor is, gedoen (voorbereidingstydpunte: 0, 1, 2, en 3 maande). Sensoriese eienskappe, insluitend pruim-, plantagtige-, en rosyntjiesmake, soetheid, suurheid, en frankheid, was stabiel gedurende berging. Chemiese resultate van Fase 2 was soortgelyk aan dié van Fase 1. Die chemiese en sensoriese stabiliteit van die formulasies na 24 weke van opberging in Fase 1 en Fase 2 nieteenstaande antosianienafname, het aangedui dat die formulasies voordelig kan wees vir die vrugtedrankiebedryf. Dus het rooivleis pruimnektars die vermoeë om met hoë antioksidant vrugtedrankies mee te ding.

Scientific explorations can lead to life changing discoveries or light the path for new discoveries as scientists continue to carry or pass on the torch of knowledge to current and future generations. This torch of knowledge radiates in many directions, as the path of discovery often demands a multidimensional perspective. This research explored the many aspects of metallic flavor in drinking water through applications of sensory science, medicine, health, and the environment. Humans interact with their environment through the five senses and are often exposed to contaminants through multiple routes; oral intake of trace metal contaminants through drinking water is a likely source. The biochemical mechanism by which humans are able to detect the flavor of strongly metallic agents such as iron has been previously elucidated, but little is known about population variability in the ability to sense metallic flavors. This research evaluated sensory thresholds and biochemical indicators of metallic flavor perception in healthy adults for ferrous iron in drinking water; 61 subjects aged 19 – 84 years, participated. The findings demonstrated an age-dependent sensitivity to iron indicating as people age they are less sensitive to metallic perception; impairment of olfactory functions is a contributing factor. Unlike in healthy adults, where human senses are often protective of overexposure to contaminants, and supportive of sensations of everyday life's pleasures, cancer patients often suffer from chemosensory dysfunctions. Metallic phantom taste is a commonly experienced sensation, yet very little studied aspect of this debilitating disorder. Impact of cancer therapy on chemosensory functions of patients with malignant brain tumors undergoing combined modality treatment (CMT) was explored. The results indicated that chemosensory dysfunctions of the patients can range from minimal to moderate impairment with maximum impairment developing during the 6-week CMT. Study of salivary constituents may provide clues on to the causes of chemosensory dysfunctions. On health aspects, implication of individual sensitivity to metallic flavor on beverage choices and overall water consumption was assessed in 33 healthy adults through self-reported beverage questionnaire. The results indicated that among the elderly reduced intake of drinking water coincided with reduced sensitivity to metallic flavor. The findings have important health implications in terms of hydration status and beverage choices. Finally, with environmental exposure relevance, preliminary findings on sensory properties of zerovalent iron nanoparticles (nZVI) indicated that oral exposure to nZVI may induce sensory properties different from that of ferrous iron, likely predictive of a diminished detection of metallic flavor by humans. Further research is warranted in this area.

1-4% of pulse fractions including pea protein and fiber, chickpea and lentil flour as well as soy flour and protein concentrate were selected and characterized. As preliminary results the functional properties of pulse ingredients are varied upon their protein content and pH of the food carrier. Orange juice, apple juice, yogurt and two probiotic fermented milk were selected for supplementation. 1% and 2% pulse fractions gave comparable results in terms of turbidity, cloud and visual stability, color and sensory attributes for both orange and apple juices beverages. All supplements improved the acidification rate of yogurt and probiotic cultures, but the highest effects were obtained with probiotic supplementation with lentil and soy flour. As for the main study, skim milk (9.5 % w/v solid content) was supplemented with 1-3% (w/v) lentil flour, pea flour or skim milk powder and they were inoculated with yogurt starter cultures or probiotic (L. rhamnosus). Acid production during the fermentation, the pH, syneresis, color, rheological properties (dynamic oscillation temperature sweep test at 4-50 ˚C), and sensory properties (only for yogurt) were studied after production and 28 days of refrigerated storage.1-3% lentil and pea flour enhanced acid production during yogurt fermentation, but the microbial population (CFU) of both S. thermophilus and L. bulgaricus were in the same range in all lentil and pea flour and skim milk supplemented yogurts, after production. Pea flour supplementation enhanced survival of L. bulgaricus after storage. The pH decreased from 4.5 to 4.1 in lentil flour and from 4.5 to 3.75 in pea flour supplemented yogurts, after 28 days. Syneresis in 1-2% lentil and pea flour supplemented yogurts was higher than other samples. In lentil supplemented yogurts, "a" and "L" values did not significantly differ in all samples and remained constant after 28 days whereas, "b" value increased as a result of supplementation. Pea flour supplementation did not alter redness or greenness of yogurts, but the yellowness was significantly higher than other yogurts. Yogurt with 3% lentil and pea flour had higher storage (G΄) and loss (G˝) moduli in comparison with samples supplemented with 1-3% skim milk and the control yogurt. 1-2% lentil and pea flour supplemented yogurt showed comparable sensory properties in comparison with 1-2% skim milk supplemented and control samples.1-3% lentil and pea flour enhanced acid production during probiotic fermentation, and the CFU's of L. rhamnosus were comparable with non-supplemented control sample after production. After 28 days, the CFU`s of 2% and 3% lentil supplemented probiotic were as high as 1% skim milk supplemented sample and the CFU`s of 3% pea flour supplemented probiotic was the highest followed by 3-2% skim milk and 1-2% pea flour supplemented samples. The pH decreased from 4.50 to 3.90 for lentil flour supplemented probiotics and from 4.50 to 4.04 for pea flour supplemented probiotics, over 28 days. Syneresis in 1-3% lentil and pea flour supplemented probiotic was significantly lower than other samples. All lentil flour supplemented samples had significantly lower "L" values and higher "b" and "a" values in comparison with skim milk supplemented samples. Pea flour supplementation slightly changed the color which was not as light as skim milk supplemented samples and they showed more yellowness in final product after production and storage. Probiotic fermented milk with 1-3% lentil and pea flour showed higher G΄ and G˝ in comparison with other samples.
Des légumineuses tels que des protéines et fibres de pois, farine de pois chiche, de lentille et de soja ont été sélectionnées et caractérisés. Des résultats préliminaires ont montré que des propriétés fonctionnelles ont variés en fonction de la teneur en protéines et du pH des légumineuses employées. Du jus d'orange et de pomme, du yogourt et deux laits fermentés à l'aide de probiotiques ont été supplémentés avec les différentes légumineuses à des taux de 1 à 4%. Les supplémentations à 1 et 2% ont donné des résultats comparables en termes de turbidité, de stabilité, de couleur et d'attributs sensoriels pour les jus d'orange et de pomme. L'addition de légumineuse a permis d'avoir une acidification plus rapide dans les yaourts et les cultures probiotiques, mais le effet le plus important a été obtenu avec farine de lentilles et le soja dans les cultures probiotiques. Comme précédemment, des laits écrémés (9,5% p/v) ont été supplémentés avec 1-3% (p/v) de farine de lentilles, de pois ou de poudre de lait écrémé. Ils ont été inoculés avec des cultures de yogourt, des probiotiques (L.rhamnosus). La production d'acide lors de la fermentation, le pH, la synérèse, la couleur, les propriétés rhéologiques (essai dynamique balayer oscillation de température à 40-50˚C), et les propriétés sensorielles (uniquement pour les yogourts) ont été étudiés après la production et durant 28 jours d'entreposage frigorifique. 1-3% de farine de lentilles ou de pois ont amélioré la production d'acide pendant la fermentation du yogourt, mais les UFC ont les même compte pour les laits suppléments que pour les témoins (lait écrémé). Il est a noter que L. bulgaricus avaient un meilleur taux de survie au jour 28 avec une supplémentation en farine de pois. La diminution du pH dans les yogourts est de 4,5 à 4,1 avec la farine de lentille et de 4,5 à 3,75 avec farine de pois, après 28 jours. La synérèse pour les yogourts supplémentés à 1 et 2% avec de la farine de lentille ou de pois était supérieure d'autres échantillons. Lorsque le taux de supplémentation augmente en farine de lentille ou de pois, il n'y a pas de différence significative pour les valeurs de a alors que la valeur b a augmenté en fonction de la supplémentation.Les yogourts faits de 1 a 3 % farine de lentilles et de pois 1 3% avaient un module élastique (G') et un module visqueux (G˝) plus élevés que les échantillons supplémentés en lait écrémé et que les témoins. Les Yogourts avec 1 à 2% de farine de lentilles et de pois possèdent des propriétés sensorielles comparable a celles des yogourts faits avec 1 a 2% de lait écrémé et celles des témoins. 1-3% de farine de lentilles ou de pois dans des laits avec probiotiques ont amélioré la production d'acide pendant la fermentation, et les UFC de L rhamnosus étaient comparable a ceux des témoins (lait écrémé) après production. Après 28 jours, les UFC pour les échantillons supplémentés avec 2 et 3% de farine de lentille étaient aussi élevées que ceux supplémentés avec 1% de lait écrème et les UFC pour les échantillons supplémentés avec 3% de farine de pois étaient plus élevées que ceux de tous les autres échantillons. Durant les 28 jours de production le pH diminue dans les laits probiotiques contenant de la farine de lentille de 4,50 à 3,90 et pour ceux contenant de la farine de pois de 4,50 à 4,04. La synérèse dans laits probiotiques avec 1 à 3% de farine de lentilles ou de pois a été significativement plus faible que les autres échantillons. Tous les échantillons contenant de farine de lentilles avaient significativement une valeur de L plus bas et des valeurs de b et a plus élevés en comparaison aux échantillons supplémentés en lait écrémé. L'addition de farine de pois a entraîné une modification de couleur b.Les laits probiotiques supplémentés avec 1 a 3 % de farine de lentilles et de pois ont des valeurs de G' et G˝ supérieures aux autres échantillons.

Resumo:
It has become increasingly challenging for food and beverage industries to manufacture products that meet consumers' demands and preferences. Safety, quality, and convenience are among the top priorities for today's smart consumers. On one hand, food manufacturers need to understand how their products are perceived by consumers at first glance in order to succeed in the market. For instance, an unusual appearance or a bizarre smell of a food product can ultimately lead to a total rejection by customers. On the other hand, uncovering the fundamental concepts of sensory science will advance food processing by targeting specific needs and expectations. This chapter reviews the primary attributes of sensory evaluation, the human senses and their role in sensory science, and applications of sensory technology in product development.
