以纤维素酶酶解提取、酸溶液提取、碱溶液提取3种方法提取的荷花蜂花粉可溶性膳食纤维(bee pollen soluble dietary fiber,BPSDF)为研究对象,探究提取方法对BPSDF多酚含量及常见致病菌、有益菌生长的影响.结果 表明,BPSDF中多酚主要以游离态的形式存在,纤维素酶酶解提取、酸溶液提取、碱溶液提取的游离酚分别占其总酚的81.16％,80.34％,69.59％;纤维素酶解提取的游离酚、总酚含量相对较高;碱溶液提取的结合酚含量相对较高.提取方法不同BPSDF游离酚、结合酚和总酚含量均差异显著,但对BPSDF中游离酚、结合酚的多酚组分影响较小.3种方法提取的BPSDF对大肠杆菌、金黄色葡萄球菌、白色念珠球菌均有较...

Bee Pollen Soluble Dietary Fiber(BPSDF) was extracted from Lotus bee pollen by cellulase enzymatic extraction,acid solution extraction and alkali solution extraction.The effects of three extraction methods on the polyphenols contents and the growth of harmful bacteria and beneficial bacteria were studied.The results showed that the polyphenols in BPSDF were mainly in free form.The contents of free polyphenols in BPSDF were 81.16%,80.34% and 69.59% respectively by cellulase enzymatic extraction,acid solution extraction and alkali solution extraction.The contents of free phenol and total polyphe...
