摘要：
The aim of this study was to determine the effect of heat treatment on immunoreactive properties of beta-lactoglobulin (beta-lg) in whey. Whey and beta-lg solutions were heated at various time intervals at temperatures between 60 and 100 degrees C. After heating, the samples were clarified, and protein content (by Bradford's method), quantity of beta-lg (by FPLC method), and immunoreactive properties ((ELISA) were determined. The highest increase in the immunoreactive properties of beta-lg was observed at 65 degrees C with a marked decrease at 100 degrees C. It can be concluded that the allergenicity of whey proteins can be modulated during the heat treatment depending on temperature and duration of heating.
