以甘薯渣为原料,对黑曲霉发酵提取水不溶性膳食纤维(IDF)的工艺进行研究,考察了发酵时间、料液比及接种量对 IDF 得率的影响。研究结果表明:最佳甘薯渣水不溶性膳食纤维的提取条件为发酵时间120 h、料液比1∶40、接种量6%,在此条件下 IDF 得率为24.39%,所制得的甘薯渣膳食纤维素的持水力和膨胀力分别为4.33 g/g、3.57 mL/g。
以甘藷渣為原料,對黑麯黴髮酵提取水不溶性膳食纖維(IDF)的工藝進行研究,攷察瞭髮酵時間、料液比及接種量對 IDF 得率的影響。研究結果錶明:最佳甘藷渣水不溶性膳食纖維的提取條件為髮酵時間120 h、料液比1∶40、接種量6%,在此條件下 IDF 得率為24.39%,所製得的甘藷渣膳食纖維素的持水力和膨脹力分彆為4.33 g/g、3.57 mL/g。

The sweet potato residue was fermented with aspergillus niger to extract insoluble dietary fiber (IDF).The effects of fermentation time,solid -liquid ratio and inoculation amount on the extraction yield of IDF were investigated.The result showed that the optimal extraction condition was:fermentation time 120 h, solid -liquid ratio 1∶40 and inoculation amount 6%.Under the condition,the yield of IDF was 24.39%.The water holding capacity and swelling capacity of the dietary fiber were 4.33 g/g and 3.57 mL/g respectively.
