Stabilizers are important component in manufactured products such as yoghurt. The addition of stabilizers improves body, texture, appearance, mouth feel and prevents technical defects such as synersis in yoghurts. In this study starch was extracted from plant sources (sweet potato, taro) with and without use of chemicals. Yoghurt was enriched with different levels of extracted starch. Yoghurt samples were analyzed for physicochemical and functional attributes such as pH, acidity, synersis, water holding capacity, viscosity, total solids and sensory profile. Use of chemically extracted starches at the level of 0.3-0.4% (Sweet potato) and 0.2-0.3% (Taro) in yoghurt manufacturing showed better results in terms of lowering synersis, increasing water holding capacity, viscosity and overall acceptability as compared to the yoghurt containing stabilizer i.e. gelatin 0.5% w/w. Use of starches did not significantly affect the sensory attributes. Yoghurt that contains sweet potato and taro starch at 0.5% gave excellent results for water holding capacity, viscosity and for all sensory attributes as compared to gelatin
The core objective was to evaluate the effect of probiotic fortification at three phases of formula milk administration in malnourished children. A dose related effect was determined in 30 severely acute malnourished children (6-59 months) in a double-blind, randomized design. According to the results, serum albumin levels, treatment T 2 (6 billion cfu) has significantly increased albumin levels (3.7g/dL) and the effect of phase-III (Plumpy'nut) was found to be better.Results regarding sodium levels showing probiotic-dose have significant effect (P≤0.05) in phases as well. Moreover, the effect of T 1 i.e. 3 billion cfu of probiotics has significantly reduced sodium levels (141.8mmol/L) vs. others and the effect of phase-II was better on reducing sodium levels. which is further confirmed in terms of reduced erythrocyte sedimentation rate levels at phase-III (29.566 vs. phase-II, 41.3 and phase-I, 46.533 mm/h). Conclusively, the effect of 6 billion cfu at phase-III was more effective on blood parameters.
Ample access to nutritious and healthy food is the foremost challenging issue in all over the world. Vegetables constitute integral part of human diet and considered as natural reserves of nutrients. Heavy metals are among the most toxic food pollutants and their intake through diet leads to several disorders. Vegetables get polluted with these toxicants through waste water irrigation, industrial emissions and undue application of metal-based pesticides. This situation prevails more alarming in vegetables grown in peri-urban areas as they have shown high incidence of heavy metals accumulation. Among different heavy metals arsenic, cadmium, chromium and lead are most prevalent metals that can pose threat to humans even at low concentration. In this study effort was made to mitigate these heavy metals (Ar, Cd, Cr and Pb) in cauliflower, spinach, okra and brinjal collected from peri-urban areas through washing with different biological solutions. Heavy metals contents were determined by using Atomic Absorption Spectrophotometry (AAS). A significant reduction in heavy metal contents was observed as a result of washing with different biological solutions. Unwashed vegetable samples were found to be heavily contaminated with heavy metals but washing of vegetables with 8% ginger solution was found to be more effective.
Bush tea (Athrixia phylicoides DC.) is an aromatic South African indigenous plant used for many decades as a health beverage and medicine.Several studies have extensively investigated wild bush tea's secondary metabolites, but the entire profiling of cultivated bush tea's metabolites is limited in the literature. Thus, the objective of this study was to profile cultivated bush tea metabolites using liquid chromatography-quadrupole time of flight-tandem mass spectrometry (LC-QTOF-MS). The 31 metabolites profiled included;
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
