Extraction,Purification and Properties Researches of Hemi-cellulose Polysaccharides from Pineapple Peel
摘要
Abstract
The pineapple hemi-cellulose polysaccharides,obtained from pineapple peel by NaOH solution extraction and ethanol precipitation,were separated and then purified by DEAE-Cellulose( OH-) column. The optimal processing of pineapple hemi-cellulose polysaccharides extraction was:extracting time of 2h,ratio of material and 7% NaOH ( w: v) 1: 10,extracting temperature of 40℃. The yield of hemi-cellulose and content of pentosans are 41. 3% and 73 % respectively. Three kinds of purified hemi-cellulose polysaccharides by freeze-drying were obtained. The hemi-cellulose polysaccharides-1,2 were basically not composed of monosaccharide,starch,protein and nucleic acid. The hemi-cellulose polysaccharides-2 was showed a typical polysaccharide FT-IR spectrum profile.关键词
