  • Applications

    Protein hydrolyzates, yeast (CAS 100684-36-4) are a peptide- and amino acid-rich ingredient used as a nitrogen source and nutrient supplement in industrial fermentation and cell culture media; they are commonly used in animal feed and aquaculture formulations as a protein supplement; in agriculture they serve as a biostimulant and soil/foliar nutrient additive; in cosmetics and personal care they function as conditioning agents and humectants delivering amino acids to skin and hair; in food processing they act as flavor enhancers contributing to umami and as a nutritional ingredient in formulated products.
