摘要

Extracting of peanut protein by ultrasound-assisted reverse micelles,the reverse micelle systems were formed by sulphosuccinic acid bis (2-ethylhexyl) ester sodium salt(AOT),isooctane and KCI buffer solution.The effects of adding amount of peanut powder,reverse micelles concentration,ultrasonic time,ultrasonic temperature,ultrasonic power,water content(W0),KCI concentration and pH on the forward extraction rates were investigated.The results showed that the optimum conditions of forward extraction were:adding amount of peanut powder 0.015 g/mL,reverse micelles concentration 0.06 g/mL,ultrasonic time 20 min,ultrasonic temperature 40 ℃,ultrasonic power 180 W,water content (W0) 16,KCI concentration 0.2mol/L and pH 8.5.Under this optimum conditions,the forward extraction rates of peanut protein reached 89.59%.Using the extraction method assisted by ultrasound improved the extraction rates of protein and shorten the extraction time.%采用超声波辅助反胶束法提取花生蛋白,利用由琥珀酸二(2-乙基己基)酯磺酸钠(AOT)-异辛烷-氯化钾缓冲溶液组成的反胶束体系,从花生粉中提取蛋白质.以花生蛋白萃取率为指标,考察了花生粉加入量、反胶束浓度、超声时间、超声温度、超声功率、W0、KCl浓度、缓冲溶液pH对花生蛋白前萃率的影响.结果表明最佳前萃工艺条件为:花生粉加入量0.015 g/mL,反胶束浓度0.06 g/mL,超声时间20 min,超声温度40℃,超声功率180 W,W016,KCl浓度0.2 mol/L,pH8.5.在此条件下,花生蛋白的前萃率达89.59%.采用超声波辅助萃取的方法,提高了蛋白萃取率,缩短了萃取时间.
