The invention discloses an extracting method of
oyster peptides. The extracting method comprises the following steps: homogenizing after viscera is removed from
oyster meat, firstly adding active dryyeasts and
arabinose for deodorization, then adding beta-
cyclodextrin for treatment, adding complex
proteases for constant-temperature
enzymatic hydrolysis after a pH value of a deodorized
oyster meathomogenate is regulated, performing
enzyme inactivation after the end of
enzymatic hydrolysis, filtering centrifugal supernatant, freezing and
drying to obtain the oyster peptides. The extracting method disclosed by the invention has the benefits that the extracting method has the advantages of being low in input, simple to operate, good in
protein degradation effect, high in oyster
peptide yield, high in sensory acceptance and easy for industrialized scale production; the molecular weights of the obtained oyster peptides are uniformly distributed, and the content of the oyster peptides withmolecular weights
ranging from 4000 to 6000 is more than 87 percent, therefore, application values and market potentials are good.
