| Research Abstract |
Major whey protein beta-lactoglobulin (BLG) was conjugated with epsilon-polylysine (PL) by using microbial transglutaminase (MTGase) to improve the function of BLG. The molar ratio of BLG to PL in the conjugate was 1:1.2. Native conformation of BLG was almost maintained after conjugation with PL. By conjugation with PL, the improvement in the emulsifying ability and the reduction of the immunogenicity were achieved. Further conjugation with dextran (Dex) led to the effective reduction of the immunogenicity of BLG.
