摘要: 研究超声波技术改变小麦面筋蛋白的功能特性。通过单因素试验,研究底物浓度、超声功率、超声时间及pH值对溶解度的影响,得出了最佳影响范围;根据中心组合一致精度的设计(Uniform precision)的中心组合试验设计原理对改性工艺进行优化,结果表明:当底物浓度为8.8%、超声功率为720W、超声时间为8min、pH值为8.5时,蛋白溶解度可达4.11mg/ml。

Abstract: For improving functionalities of wheat gluten protein,its physical modification by ultrasonic was studied. Based on the solubility index,single factor tests were done at first to estimate the proper ranges of main affecting factors,and then the factors were optimized based on central composite design theory of Uniform precision. The results showed that under the conditions of substrate concentration 8.8%,ultrasonic power 720 W,ultrasonic time 8 min and pH 8.5,the solubility reaches 4.11 mg/ml.
