摘　　要：探讨了以香蕉茎干为原料,用微波提取水溶性膳食纤维的工艺及其操作条件,并与直接水提法进行比较。结果表明,微波法最佳工艺条件为提取时间2min、提取功率900W、液料比为2ml/g、pH4,此条件下SDF干基产率达到9.86%。微波法工艺明显优于直接水提法。In this study, the microwave extraction technology of water soluble dietary fiber from banana pseudo stem was optimized based on several single factor tests and L9(34) orthogonal test. The results showed that the optimal microwave extraction time, power, ratio of liquid to solid and pH value of extractant (water) are 2 min, 900 W, 2 ml/g and pH 4, respectively. Under these conditions, the dry yield of soluble dietary fiber reaches 9.86%, which is higher than that of 7.90% obtained by the direct hot water ex...
