Abstract

|
|
|
The heat treatment indicators such as HMF contents, lactulose contents and whey protein denaturation rates were measured to refer to the heat treatment intensity of domestic market infant formulae. The HMF contents showed 21.0-43.9 umol/l: in the case of powder types, the HMF contents in enriched nutrient products(ii) were higher whereas in the case of liquid types they were packed in cans(i). The lactulose contents showed 2.5-11.4 mg/100 ml in the powder type and 27.0-164.8 mg/100 ml in the liquid type. There was much difference in the lactulose contents according to the product types. Compared with the ADPI standards, most of infant formulae were considered to be medium-heat class. The whey protein denaturation rates were 1.1-69.4% in the powder type and 37.4-71.3% in the liquid type.
