摘要
通过单因素和正交实验,确定压热法制备燕麦抗性淀粉的最佳工艺参数为:淀粉乳浓度20%、pH6·0,经沸水预糊化后在121℃压热处理50min,冷却至室温,在4℃条件下保存24h,80℃烘干24h。按该工艺制备燕麦抗性淀粉,其得率可以达到17·26%。
The autoclave method for preparation of oat resistant starch was investigated by single factors and designing orthogonal test.The optimal parameters were.starch concentration 20%, pH 6.0,after pregelatinization in boiling water,autoclaving treatment at 121℃,50min,then cooling to nature temperature.The resistant starch was storied at 4℃ for 24h,then drying at 80℃ for 24h.The productivity of oat resistant starch could be achieved 17.26%.
