Soybean protein isolate(SPI) and sodium alginate(SA) were used as the main materials,and SPI-SA conjugates were prepared by dry-heat reaction to improve the emulsifying properties of SPI.The single factor experiments showed that the effects of the reaction time,reaction temperature and SA dosage on the emulsifying capacity and emulsion stability of SPI-SA conjugates were significant.Based on the results of single factor experiments,response surface methodology(RSM) was used to optimize the preparing conditi... |
