摘要
为研究超微粉碎对荸荠皮膳食纤维的影响,考察了不同超微粉碎时间下荸荠皮膳食纤维质量分数、组成,以及可溶性膳食纤维的溶出速度。结果表明,通过超微粉碎,荸荠皮总膳食纤维质量分数提高了8.57%,同时,不溶性膳食纤维质量分数下降了21.19%,而可溶性膳食纤维能提高了137.84%。此外,通过超微粉碎处理,荸荠皮可溶性膳食纤维的溶出速度能得到显著提高。
To evaluate the effect of ultra-fine pulverization on the dietary fiber in Eleocharis tuberose peel,the total content,composition of dietary fiber and dissolution velocity of soluble dietary fiber（SDF） in E.tuberose peel powder treated by ultra-fine pulverization for different time were determined.The results showed that after ultra-fine pulverization,the total dietary fiber content in E.tuberose peel increased by 8.75%;Meanwhile,the insoluble dietary fiber content decreased by 21.19% while soluble dietary fiber content increased by 137.84%.In addition,the dissolution velocity of soluble dietary fiber in E.tuberose peel was observably rised by ultra-fine pulverization.
