The modification conditions of soy protein isolate ( SPI) solution for coating by alkali was stud-ied. The effects of mass concentration of SPI, sodium hydroxide dosage, modification temperature and modification time on the modification of SPI solution were researched. The modified SPI was characterized by ultraviolet spectrum and infrared spectrum. The results showed that the suitable modification condi-tions were obtained as follows:mass concentration of SPI 8. 16%, dosage of 0. 05 g/mL sodium hydrox-ide solution 9 mL ( the total volume of water and sodium hydroxide solution 180 mL) , modification tem-perature 60℃ and modification time 30 min.
