摘　　要：本文对酸碱处理法提取红枣膳食纤维的条件进行了研究。得到最佳提取条件为:红枣5g,硫酸溶液浓度1.5%、硫酸溶液量150m L、硫酸溶液水解时间40min、氢氧化钾溶液浓度1.75%、氢氧化钾溶液量100m L、氢氧化钾溶液水解时间30min。在该条件下红枣膳食纤维提取率达5.1%。The extraction condition of dietary fiber from red dates was studied by acid and alkali treating method. The optimized extraction conditions were determined as follows： red dates 5g, sulfuric acid solution mass concentration 1.5%, sulfuric acid solution volume 150mL, sulfuric acid solution hydrolysis time 40min, potassium hydroxide solution mass concentration 1.75%, potassium hydroxide solution volume 100mL, potassium hydroxide solution hydrol- ysis time 30min. The extraction ratio was 5.1%.
