Abstract:The physical modification conditions of alcohol leached peanut protein concentrate ,such as solution temperatue,solution pH,ultrasound time,were studied.Through orthogonal test,the optimum conditions were obtained
as follows；100℃ water used to dissolve the protein concentrate,ration of solid to liquid 1:9,solution pH9,ultrasonic wave power 300W,frequency 25kHz,ultrasound time 30 min.In these conditions,the content of protein in the modified was 65.86%(N×6.25，dry basis),and NSI was 64.68%. |
