Protein Hydrolysate is a complex combination of peptides having different chain length with free amino acids. It is widely used in the production of food and feed additives owing to its high content of different types of proteins such as soy protein, gelatin, caseins, etc. This is highly beneficial in the making of food products and human health. It is developed by heating the purified protein sources with acid as every protein hydrolysate is a complex mixture of peptides having different chain lengths with free amino acids. This Protein Hydrolysate is prepared using corn, milk, peanuts, soybeans, wheat, yeast, or gelatin. It comes with different degree of hydrolysis to be used in foods as flavor enhancers. In addition, it is also used for texture improvement, water binding, emulsification, etc.
