Abstract

We report the application of a method which combines digestion with pancreatin and neutral detergent treatment in the analytical study of dietary fiber from cassava. The use of pancreatin previous to the detergent extraction enabled rapid filtration, thus giving more reproducible results for neutral detergent fiber (NDF). Acid detergent fiber (ADF), hemicellulose, lignin and pectin were also determined. The values obtained for NDF (4.65%) and pectin (1.17%) are very important, considering their role in the digestive process.

摘要

我们报告了一种结合胰蛋白酶消化和中性洗涤剂处理的方法在木薯膳食纤维分析研究中的应用。在洗涤剂提取之前使用胰蛋白酶可实现快速过滤，从而为中性洗涤剂纤维（NDF）提供更可重复的结果。还测定了酸性洗涤剂纤维（ADF）、半纤维素、木质素和果胶。考虑到它们在消化过程中的作用，所获得的NDF值（4.65%）和果胶值（1.17%）非常重要。
