摘 要: 本试验采用超声波技术从全荞麦粉中提取荞麦蛋白(BWP),分别研究了超声处理时间、频率以及溶液pH值、液料比和原料粒度对荞麦蛋白(BWP)提取率的影响。结果表明最佳提取条件为溶液pH8.0,超声处理时间15min,超声频率15KHz,液料比20:1(mL:g),BWP提取率可达75%以上,产品纯度为77.33%。 An ultrasonic method to extract protein from buckwheat was studied. Extraction conditions were optimized by examining factors including ultrasonic time, frequency, pH of the solution, ratio of water-to-meal and granularity. It is indicated that the optimum extraction conditions are: pH8.0, ultrasonic time 15min, ultrasonic frequency 15KHz and ratio of water-to-meal 20 : 1 (mL: g) . And the ultrasonication can extract more than 75% of total proteins from buckwheat. The purity of product is 77.33%.
