Abstract:
A procedure was developed to determine the degree of hydrolysis (DH) of whey protein hydrolysates (WPH) during hydrolysis in either 3 kDa or 10 kDa tangential-flow filter (TFF) enzymatic membrane reactors (EMR). Protease N Amano G (IUB 3.4.24.28, Bacillus subtilis) was used to hydrolyse an initial 5% (w v *1) aqueous solution of whey protein isolate (86.98% protein) at pH 7.0 and 55 °C with continuous recirculation and simultaneous removal of hydrolysates through the TFF, in single- or two-stage...     »
