Effect of Soybean Protein Isolate-7s on Delphinidin-3--Glucoside from Purple Corn Stability and Their Interactional Characterization.

Anthocyanins are abundant in purple corn and beneficial to human health. Soybean protein isolate-7s (SPI-7s) could enhance the stability of anthocyanins. The stable system of soybean protein isolate-7s and delphinidin-3--glucoside complex (SPI-7s-D3G) was optimized using the Box-Behnken design at pH 2.

Effect of soybean insoluble dietary fiber on prevention of obesity in high-fat diet fed mice via regulation of the gut microbiota.

Increasing evidence has shown that the gut microbiota plays an important role in preventing obesity; however, the mechanism by which insoluble dietary fiber (IDF) prevents high-fat diet (HFD)-induced obesity remains unclear. This study aimed to investigate the effect of SIDF on obesity in HFD mice and determine the mechanism by which it prevents obesity through regulating the gut microbiota. Soybean insoluble dietary fiber (SIDF) was used as an intervention in HFD mice for 20 weeks.
