【摘要】 以蕨根淀粉为试验材料，采用单因素试验和Box-Behnken试验优化微波法制备蕨根淀粉的工艺条件。微波法制备蕨根抗性淀粉优化工艺条件为微波时间1 min、微波功率480 W、淀粉乳浓度20%、回生温度4℃、回生时间24 h。该条件下，蕨根抗性淀粉含量为14.21%，明显高于原蕨根淀粉的抗性淀粉含量（1.02%）。更多还原

【Abstract】 This study optimized the conditions for preparing fern root resistant starch using microwave method by single factor experiment and Box-Behnken test. The optimal conditions for preparing fern root resistant starch were determined as follows:microwave treatment for 1 min at 480 W,starch milk concentration at 20%,regeneration at 4 ℃ for 24 h. The content of fern root resistant starch under such optimal conditions was 14.21%,which was significantly higher than that of the original fern root starch(1.02%).更多还原
