采用体外发酵技术比较4种粮食发酵特性,评价高粱、黄豆、早籼米(糙米和精制白米)发酵性能。将4种食物制成冻干粉加入培养基,接种人体新鲜粪便进行体外发酵,定点记录发酵液产气量、测定pH、氨和SCFA含量。黄豆组产气量最大,空白组产氨量最多且pH最高,高粱组pH最低,产氨量最少。高粱组总短链脂肪酸含量最高,空白组最低。4种粮食体外发酵有助于增加SCFA,高粱优于其他三种。
採用體外髮酵技術比較4種糧食髮酵特性,評價高粱、黃豆、早秈米(糙米和精製白米)髮酵性能。將4種食物製成凍榦粉加入培養基,接種人體新鮮糞便進行體外髮酵,定點記錄髮酵液產氣量、測定pH、氨和SCFA含量。黃豆組產氣量最大,空白組產氨量最多且pH最高,高粱組pH最低,產氨量最少。高粱組總短鏈脂肪痠含量最高,空白組最低。4種糧食體外髮酵有助于增加SCFA,高粱優于其他三種。

The effects of four kinds of foodstuff (sorghum, soybean, unpolished rice and fine rice) on fermentation characteristics were evaluated with fermentation technology in vitro. Freeze-dried powder of these food and fresh feces of two donors were added to the culture medium. The gas production , pH and the contents of NH3-N, acetic acid, propanoic acid and butyric acid in the fermentation broth were determined at different time points. Our data showed that the maximum volumes of gas production in soybean-supplemented group , the maximum pH values and NH3-N contents in free-supplemented group, the lowest pH values and the least NH3-N contents in sorghum-supplemented group. The contents of short chain fatty acids (SCFA) were the highest in sorghum-supplemented group and the least in free-supplemented group. Sorghum, soybean, unpolished rice and fine rice are beneficial for increasing SCFA production and sorghum was the best of all.
