METHOD FOR ENRICHING FUNCTIONAL PEPTIDE IN MEAT, AND FOOD PRODUCT USING MEAT HAVING ENRICHED FUNCTIONAL PEPTIDE

PROBLEM TO BE SOLVED: To provide a method for enriching functional peptides, capable of increasing the content of functional peptides primarily derived directly from meat or seafood as main raw material for foods.SOLUTION: The method for enriching functional peptides includes a step of sodium bicarbonate treatment for immersing raw meat in a sodium bicarbonate solution or injecting sodium bicarbonate solution to raw meat and a step of high pressure treatment for applying high pressure of 100 MPa to 500 MPa to the meat. In the step of sodium bicarbonate treatment, the sodium bicarbonate solution has a concentration of preferably 0.1 M to 0.5 M. In the step of high pressure treatment, the pressure time is preferably 5 min to 60 min. In the case of immersing meat in a sodium bicarbonate solution, the immersion time is preferably 30 min to 60 min. For example, when pork is selected as the meat, the content of anserine and carnosine in the meat can be relatively easily increased.
