The application dimension of the Casein Hydrolase market is the primary driver of revenue distribution, as reflected in the accompanying pie‑chart. Dairy processing accounts for the largest share (≈35%), where the enzyme is employed to modify protein solubility, reduce bitterness, and improve texture in liquid milk and yogurt. Nutraceuticals represent roughly 25% of the market; here, hydrolyzed casein peptides are valued for their bioactive properties, such as antihypertensive and immunomodulatory effects, commanding premium pricing. Infant formula contributes about 20%; enzymatic hydrolysis enhances digestibility and reduces allergenicity, meeting stringent regulatory standards. Functional foods hold a 12% slice, leveraging casein hydrolysates as flavor enhancers and protein supplements in sports drinks and snack bars. Finally, cheese manufacturing comprises the remaining 8%, where controlled proteolysis influences ripening kinetics and flavor development. This Casein Hydrolase segmentation illustrates how each application niche translates into distinct market size contributions, guiding strategic investment and R&D allocation.
