| 摘 要： | 采用人粪便提取液为接种物，通过体外发酵技术研究不同改性处理的葡萄皮渣膳食纤维在模拟人体大肠环境条件下的发酵过程，测定不同发酵时间的pH值和短链脂肪酸(SCFA)的含量。结果表明：葡萄皮渣膳食纤维是一种理想的可被大肠微生物所利用的碳源，能够在体外模拟环境下发酵产生乙酸、丙酸、丁酸和异丁酸等短链脂肪酸；葡萄皮渣膳食纤维经过不同改性处理后对其发酵液pH值的变化无明显影响，但对发酵液中短链脂肪酸的总量和各组分含量均有一定影响。

| Abstract: | Human excrement extract was used as the inoculum to modify grape pomance dietary fiber in a mimic human intestinal environment by in vitro fermentation.The pH and the content of short-chain fatty acids(SCFAs) in modified dietary fiber obtained after different times of fermentation were determined.The results indicated that grape pomance dietary fiber was one of ideal carbon sources that could be exploited by intestinal microflora.SCFAs including acetic acid,propionic acid,butyrate acid and isobutyrate acid ... |
