Abstract:
Whey protein isolate (93.84 % protein) was hydrolysed using bovine trypsin (EC 3.4.21.4) at an enzymeto-substrate ratio of 1.0 % (w w1) over a range of temperatures and pH. Residual protein was quantified using reversed-phase high performance liquid chromatography. Genetic variants A and B of b-lactoglobulin (b-Lg) and a-lactalbumin (a-La) showed higher resistance to trypsin hydrolysis at 25 C than at 50 C with higher susceptibility of b-LgA than of b-LgB. Under the conditions trialled, the h...     »
