摘要:

采用内切木聚糖酶酶解小麦麸皮不溶性膳食纤维制备阿魏酸糖酯。研究表明阿魏酸糖酯具有螯合金属离子、清除H2O2、羟自由基、DPPH 自由基的作用;与人工合成抗氧化剂BHT、VC 相比,阿魏酸糖酯仍然表现出很强的抗氧化性质,而且比游离态阿魏酸的抗氧化性质高。

关键词: 小麦麸皮, 阿魏酸糖酯, 自由基, 抗氧化性质

Abstract:

The ferulic acid sugar esters prepared from wheat bran hydrolyzed by endo-xylanase were characterized for their antioxidant properties in vitro reflected by the abilities to scavenge hydrogen peroxide as well as hydroxyl and DPPH free radicals and to chelate metals using two synthetic antioxidants, BHT and VC, as the controls. The sugar esters were found to have strong antioxidant properties, which were better than those of free ferulic acid.

Key words: wheat bran, ferulic acid sugar esters, radicals, antioxidant properties
