Article Abstract

The considerable value of whey is evident from its significant potential applications and contributions to the functional food and nutraceutical market. The by-products were individually obtained during functional and novel soy cheese production using defined lactic acid bacterial strains of Sikkim Himalaya's traditional . Hydrolysis of substrate proteins by starter proteinases resulted in a comparable peptide content in whey and soy whey which was associated with antioxidant and ACE inhibition potential. Peptidome analysis of WS4 whey and soy whey revealed the presence of several bioactive peptides including the multifunctional peptides PVVVPPFLQPE and YQEPVLGPVRGPFPIIV. analyses predicted the antihypertensive potential of whey and soy whey peptides with strong binding affinity for ACE active sites. QSAR models predicted the highest ACE inhibition potential (IC) for the β-casein-derived decapeptide PVRGPFPIIV (0.95 μM) and the Kunitz trypsin inhibitor protein-derived nonapeptide KNKPLVVQF (16.64 μM). whey and soy whey can be explored as a valuable source of diverse and novel bioactive peptides for applications in designer functional foods development.

Unlabelled: Soy whey, a tofu production byproduct rich in nutrients, is typically discarded. This study investigated five natural lactic acid bacteria (LAB) strains isolated from spontaneously fermented soy whey (FSW) for their fermentation performance in soy whey medium. The growth characteristics, total phenols and flavonoids compounds, antioxidant activities, and aroma profiles were evaluated.

The rising demand for sustainable protein is driving interest in insects as a raw material for advanced food ingredients. This review collates and critically analyses over 300 studies on the conversion of crickets, mealworms, black soldier flies, and other farmed species into powders, protein isolates, oils, and chitosan-rich fibers with targeted techno-functional roles. This survey maps how thermal pre-treatments, blanch-dry-mill routes, enzymatic hydrolysis, and isoelectric solubilization-precipitation preserve or enhance the water- and oil-holding capacity, emulsification, foaming, and gelation, while also mitigating off-flavors, allergenicity, and microbial risks.

Background: Protein is a primary nutrient in concentrate supplementation for donkey foals, and the source of this protein significantly influences their growth and development. Milk-derived protein sources, such as milk powder, casein, and whey protein, are widely used in milk replacers for donkey foals due to their balanced nutritional profiles, high digestibility, and high bioavailability. However, the increasing costs of milk powder and whey protein have prompted researchers to explore alternative protein sources, with soy protein being a particularly promising option.
