硫酸酯化甜玉米芯多糖的制备
Sulfated modification of polysaccharides from sweet corn cobs
摘要
Abstract
Polysaccharides were extracted and purified from sweet corn cobs , and sulfated modification with the method of sulfuric acid .The dosage of ammonium sulfate, the volume of concentrated sulfuric acid and reaction time was selected with degree of substitution as in -dex by orthogonal design.The solubility of sulfated modification of polysaccharides was de -termined.The optimum conditions were as follows: the dosage of ammonium sulfate , the vol-ume of sulfuric acid and the reaction time were 0.06 g, 4 mL and 30min, respectively.The degree of substitution was up to 1.1427.The solubility of sulfated modification of polysac -charides had good solubility with optimum conditions .关键词
