The interaction of soy protein isolate (SPI) and its hydrolysates (SPIHs) with cyanidin-3-O-glucoside (C3G) at pH 7.0 were investigated to clarify the changes in the antioxidant capacity of their complexes. The results of intrinsic fluorescence revealed that C3G binds to SPI/SPIHs mainly through hydrophobic interaction, and the binding affinity of SPI was stronger than that of SPIHs. Circular dichroism and Fourier-transform infrared spectroscopy analyses revealed that the interaction with C3G did not significantly change the secondary structures of SPI/SPIHs, while the surface hydrophobicity and average particle size of proteins decreased. Furthermore, the SPI/SPIHs-C3G interaction induced an antagonistic effect on the antioxidant capacity (ABTS and DPPH) of the complex system, with the masking effect on the ABTS scavenging capacity of the SPIHs-C3G complexes being lower than that of the SPI-C3G complexes. This study contributes to the design and development of functional beverages that are rich in hydrolysates and anthocyanins.

This study aims to evaluate the effects of soy soluble polysaccharide and soy hull polysaccharide on stability and characteristics of emulsions stabilised by soy protein isolate in an in vitro gastric environment. Zeta potential and particle size were used to investigate the changes of physico-chemical and stability in the three emulsions during in vitro gastric digestion, following the order: soy protein isolate–stability emulsion < soy protein isolate–soy soluble polysaccharide –stability emulsion < soy protein isolate–soy hull polysaccharide–stability emulsion, confirming that coalescence in the soy protein isolate–stability emulsion occurred during in vitro gastric digestion. Optical microscopy and stability measurement (backscattering) also validate that addition of polysaccharide (soy soluble polysaccharide and soy hull polysaccharide) can reduce the effect of simulated gastric fluid (i.e., pH, ionic strength and pepsin) on emulsion stability, especially, soy protein isolate–soy hull polysaccharide–stability emulsion, compared with soy protein isolate–stability emulsion. This suggests that the flocculation behaviours of these emulsions in the stomach lead to a difference in the quantity of oil and the size and structure of the oil droplets, which play a significant role in emulsion digestion in the gastrointestinal tract. This work may indicate a potential application of soy hull polysaccharide for the construction of emulsion food delivery systems.

Genistein proposed as a treatment for osteoporosis for postmenopausal women, elderly men, lowering cardiovascular disease and reduces hormone dependent cancers. Genistein also exerted inhibitory effect on lipid peroxidation induced in vitro by pro-oxidant agents on model and natural membranes on cultured cells and on low density lipoprotein. Genistein detection in soy products is very much important for Food Scientist. Gensitein can be detected by UV-Visible spectrophotometric and HPLC method. This study focused on the detection of genistein by HPLC and spectrophotometric methods. Genistein content of both soy protein isolate (SPI) and spray dried soy milk powder (SMP) was determined by spectrophotometry (93.12±1.15 and 74.78±0.75 mg/100g, respectively) were slightly higher but not significantly differ than HPLC analysis (89.67±5.16 and 72.34±0.27 mg/100g, respectively). This study suggested that genistein and its glycoside could be detected by spectrophotometric methods with high accuracy.
