酶处理马尾藻提取膳食纤维的研究

Extraction of Dietary Fiber from Enzyme-treated Sargassum

采用酶处理和化学的方法 ,研究了酶解、消化、漂白和功能活化等工艺条件对马尾藻膳食纤维提取的影响 ,筛选出马尾藻膳食纤维提取的最佳工艺条件。结果表明 ,在该工艺条件下提取的马尾藻膳食纤维的产率为 2 7 3 % ,颜色为类白色 ,膳食纤维干基含量为 82 7% ,钙含量为 5 3 6% ,膨胀力和持水力两项功能性指标分别达到 10 8mL/g和 5 3 2 0 % 。

The optimal process conditions of dietary fiber(DF) extration from Sargassum were studied using enzymatic and chemical method. The results at optimal conditions for extracting Sargassum DF were 27.3% of yield, nearly white in color, 82.7% of DF contents, 5.36% of calcium, 108mL/g of expansion capacity and 5?320% of water holding capacity. The quality of the product was much better than wheat bran DF.
