Abstract

The comparative investigation of physico-chemical properties of plant (guar gum, konjac-mannan) and microbial (xanthan gum) origin structurants have been carried out. Among them, xanthan sigma (1544 mPa) and konjac-mannan (5000 mPa) have the best initial viscosity. It has been shown that due to molecular-mass characteristics xanthan (74.3%) gum, ksampan (39%) and konjac-mannan (42.1%) have the highest percentage of high-weight fractions. It has been established that mannose, glucose and galactose as well as unidentified substances are presented in different concentrations in the structure of structurants.

摘要

对植物源（瓜尔胶、魔芋甘露聚糖）和微生物源（黄原胶）结构剂的物理化学性质进行了比较研究。其中，黄原胶（1544毫帕斯卡）和魔芋甘露聚糖（5000毫帕斯卡）具有最佳的初始粘度。结果表明，由于分子量特性，黄原胶（74.3%）、魔芋胶（39%）和魔芋甘露聚糖（42.1%）具有最高比例的高重量级分。已经确定，甘露糖、葡萄糖和半乳糖以及未鉴定的物质在结构剂的结构中以不同浓度存在。
