摘　　要：以粗杂粮粉为原料,分成非发酵粉和发酵粉2组,利用体外模拟消化试验研究多酚、黄酮的最佳释放时间,模拟肠液透析得出多酚和黄酮的生物利用率。结果表明:体外模拟消化过程中多酚、黄酮最佳释放时间为胃消化1 h,肠消化2 h;发酵可以提高多酚、黄酮的释放量;非发酵粉和发酵粉中多酚、黄酮的生物利用率分别为10%、12%和11%、12%。Coarse grains powder was used as material,and divided into two groups:non-fermented powder and fermented powder.The optimal release time of polyphenols and flavones was used vitro simulated digestion and the bioavailability of polyphenols and flavones was obtained by simulated intestinal dialysis.The results showed that:the optimal release time of polyphenols and flavones during in vitro simulated digestion was 1 h in gastric digestion and 2 h in intestinal digestion;fermentation could increase the release of polyphenols and flavones;the bioavailability of polyphenols/flavones in non-fermented powder and fermented powder were 10%、12%and 11%、12%respectively.
