(57) [Summary] (Modified) [Structure] A hydrolyzate of whey protein having a purity of at least 70% (by weight) and having a molecular weight of 5,000 to 10,0. The fraction of 00 daltons is less than 1% (by weight) of the total hydrolyzate, and the residual antigen activity measured by the ELISA inhibition test method using anti-whey protein serum is 10 -5 or less. The ratio of the amount of free amino acid to the total amount of amino acid in the decomposed product is 10 to 15% (weight), and the ratio of the amount of free lysine to the amount of total lysine contained in whey protein is 12 to 20% (weight). ) And an ammonia content of 0.2% (weight) or less, and a whey protein hydrolyzate having a good flavor, and a method for producing the same. [Effects] As a protein source material for infants with poor digestion and absorption capacity or elderly persons with impaired digestion and absorption capacity, sick people, allergy patients, infants, pregnant women, and sick people with reduced immune function for the purpose of allergy prevention Can be used. |
