摘要
[目的]优化超声提取胡麻胶的工艺。[方法]在单因素试验的基础上,选择超声功率、提取温度、提取时间、提取次数为自变量,胡麻胶提取率为响应值,利用Box-Behnken试验和响应面分析法,研究各自变量及交互作用对胡麻胶提取率的影响。[结果]超声提取胡麻胶最佳工艺参数:超声功率280 W、提取温度56℃、提取时间57 min,在此条件下,胡麻胶提取率达14.62%。[结论]该工艺切实可行,可为胡麻胶的高效提取提供理论依据。
[Objective] The aim was to optimize ultrasonic extraction of flaxseed gum.[Method] On the basis of single factor experiment, se-lecting ultrasonic power, extraction temperature, time, times as independent variables, extraction yield of flaxseed gum as response value, u-sing Box-Behnken experiment and response surface analysis method, effects of each variable and interaction on extraction yield of flaxseed gum were studied, the prediction model of quadratic polynomial regression equation was simulated.[ Result] The optimal technical parameters were： ultrasonic power 280 W, extraction temperature 56℃, time 57 min, under the above conditions, the extraction yield reached 14.62%. [Conclusion] The technique is feasible, which can provide technical basis for high efficiency extraction of flaxseed gum.
