To compare the extent of heat treatment in domestic infant formula, pH, titratable acidity, undenatured whey protein contents, HMF contents and protein-reducing substances of three commercial products (A, B, C) were measured. The pH of B products was lowest and the titratable acidity of B product was highest. The contents of undenatured whey protein per 100ml serum were 0~30㎎(A products), 90~130㎎(B products) and 80~90㎎(C products), respectively. Distinct differences of undenatured whey protein contents according to the manufacturer and infant’s stage in age could be observed. The HMF contents of tested products showed 10.9~21.5μ㏖/L and B-2 product(B products for the second stage of 5~9 month) was the highest among tested products. The protein-reducing substances showed 4,46~9.50㎎ K₄Fe(CN)_6/100ml serum and B-2 product was the highest among tested products.
