摘要 利用高压糊化-普鲁兰酶工艺制备黑苦荞抗性淀粉,采用响应面法优化黑苦荞抗性淀粉制备条件。在单因素实验基础上选取因素和水平,以高压糊化时间、酶解时间和酶添加量为影响因子,采用中心组合法进行3因素3水平实验设计,建立了制备工艺的二次多项数学模型,并验证了该模型的有效性,得到了最优工艺参数:高压糊化时间23 min、酶解时间4.43 h、酶添加量14 ASPU/g,得到黑苦荞抗性淀粉得率为(32.36±0.24)%,基本符合理论预测值(32.35%)。 The black Tartary buckwheat resistant starch was prepared using an autoclave-pullulanase process,and the response surface methodology was used to optimize the resistant starch preparation conditions.Based on the single-factor test,a 3-factor,3-level experimental design was conducted by using the central group method with autoclaving time,enzymatic digestion time and enzyme addition as the influencing factors,and a quadratic multinomial mathematical model was established for the preparation process,as well as the validity of the model was verified.The optimal process parameters were obtained:autoclaving time of 23 min,enzymatic digestion time of 4.43 h,and enzyme addition of 14 ASPU/g.The yield of resistant starch of black Tartary buckwheat was(32.36±0.24)%,basically consistent with the predicted value of the model(32.35%).
