摘要
Abstract
Mesona blume gum was extracted from Mesona blume by boiling alkaline water extraction and alkaline water extraction assisted by ultrasonic. The raw material was from Paitan Town, Zengcheng city. The extraction methods,inherent viscosity and polysaccharide content of the gum were studied. The optimal extraction conditions of boiling alkaline water extraction method were: material -liquid ratio was 1: 40, Na2 CO3 concentration was 0. 3％, extraction time was 90min, and the yield of mesona blume gum was 36. 80％. The optimal extraction conditions of alkaline water extraction method assisted by ultrasonic were: Na2CO3 concentration was 0. 3％, material -liquid ratio was 1: 40, and ultrasonic power was 600W, extraction time was 60min, the yield of gum was 38. 12％. The intrinsic viscosity of the gum extracted by the former method at 25℃ was 99. 608mL/g, and that of the latter one was 117. 33mL/g. The polysaccharide content of the former gum was 216. 27mg/g, and that of the latter gum was 309.08mg/g.关键词
