Stability and in vitro digestion simulation of soy protein isolate-vitamin D3 nanocomposites

Nanocomposites were prepared with soy protein isolate and vitamin D3 (SPI-VD3) as raw materials under high-pressure homogenization conditions to study their stability and in vitro digestion. Various nanocomposites of SPI and VD3 combined with high-pressure homogenization and carboxymethyl chitosan (CMC) were analyzed. The average particle size of SPI decreased from 384.4 nm to 82 nm after VD3 addition and high-pressure homogenization. When CMC...
