Protein glutaminase-mediated deamidation enables soy protein isolate to act as a stable zinc carrier with improved gastrointestinal bioaccessibility.

Poor gastrointestinal bioaccessibility limits the efficacy of conventional Zn supplements. Herein, protein glutaminase-mediated deamidation of soy protein isolate (SPI) was performed to develop a Zn delivery system. Deamidation increased the Zn-binding capacity of SPI to 29.8 mg/g protein through the formation of addit...
