响应面法优化鸭胸肉盐溶蛋白的提取工艺

Optimization of extraction conditions of duck breast salt-soluble protein based on response surface methodology

摘要: 为了得到鸭胸肉盐溶蛋白提取的最佳条件,在单因素实验的基础上,应用响应面法(RSM)优化鸭肉盐溶蛋白的提取条件确定最佳提取条件为:浸提溶液pH7.7,NaCl浓度0.5mol/L,固液比1∶5.2(g/mL),浸提时间12.3h,此时鸭胸肉盐溶蛋白的提取率可达19.9%,与理论预测值(20.4%)相差2.5%。本文为鸭肉盐溶蛋白的提取提供了一定的理论基础。

Abstract: To optimize the extraction condition for the duck breast salt-soluble meat protein (SSMP) , the optimize extraction condition was as follows:extraction solution pH of 7.7, extraction solution concentration of NaCl was 0.5mol/L, material to water ratio at 1∶5.2 (g/mL) , and extraction-duration of 12.3h, on the basis of the single factor tests.The duck breast salt soluble protein extraction rate could reach 19.9%, and the theory predicted value (20.4%) differs by 2.5%.This paper provided a certain theoretical basis on the extraction for the duck breast salt-soluble meat protein.
