利用豆渣生产高活性膳食纤维的研究

本文介绍了以豆渣为原料，采用微生物发酵和动态超高压均质处理对大豆膳食纤维进行改性研究，得到了可溶性膳食纤维含量达30％以上的高活性大豆膳食纤维。研究了不同发酵条件和不同处理压力对提高豆渣中可溶性膳食纤维（SDF）含量的影响，结果表明利用发酵法可提高可溶性膳食纤维的含量达15％以上，动态超高压均质处理法可将可溶性膳食纤维含量提高到35％以上，而发酵处理后使得超高压均质处理提高可溶性膳食纤维含量更容易，在均质压力为40MPa下均质即可将可溶性膳食纤维含量提高到30％。

Study on Production of High Activity Dietary Fiber from Soybean Dregs

The technics of using soybean dregs as the raw material with microorganism fermentation and high-pressure homogenization to process high amount of dietary fiber was introduced in this study. Effects of fermentation conditions and homogenization pressures on SDF content were studied. The results showed that the amount of SDF is increased by 15% through fermentation and by more than 20% through high-pressure homogenization. The pretreatment of fermentation is propitious to increase SDF in high-pressure homogenization, and the contents of SDF can reach 30% when homogenized at 40MPa pressure.
