Title: STUDY ON PHYSICAL MODIFICATION OF SESAME PROTEIN CONCENTRATES EXTRACTED BY ALCOHOL METHOD
Abstract: In this paper,we carried out physical modification of sesame protein concentrates by heating,microwave and ultrasonic,and analyzed the modified sesame protein concentrates.The results showed that ultrasonic had the best modification effect.Under the conditions of protein concentration 0.1 g/mL,PH value 10,ultrasonic power 400 W and ultrasonic time 3 minutes,NSI of the modified sesame protein concentrates was improved from 3.43% to 43.32%,the oil absorption was improved form 0.61 g/g to 2.62 g/g,the emulsifying capacity was improved from 0.15 to 0.22,the emulsifying stability was improved from 19.10 minutes to 36.37 minutes,the foaming ability was improved to 30.78% to 44.45%,and the foam stability was improved to 38.89% to 54.18%.
