분자량에 따라 분획된 유청단백분해물이 Bifidobacterium bifidum Bb-11 의 생장에 미치는 영향

This study was carried out to evaluate the effect of whey protein concentrate-80%(WPC-80) and whey protein isolate(WPI) on the growth of B. bifidum Bb-11. Whey proteins(α-lactalbumin, β-lactoglobulin) were digested with trypsin, then their hydrolyzates were separated into three fractions (>10,000Da, 3,000∼10,000Da,
