卡拉胶对琼脂糖凝胶不同贮存时间的渗透性及脱水效应的影响

The Study of the Storage Time Dependence on the Water Permeability and Syneresis under Compression in Iota-carrageenan Added Agarose Gels

本文利用挤压和渗透法测量不同浓度的混合凝胶在不同贮存时间下体系的脱水效应和渗透力。在琼脂糖混合凝胶的贮存过程中,脱水效应随着时间增加而增加。当琼脂糖凝胶加入卡拉胶后,脱水效应减弱,渗透性减弱,当琼脂糖凝胶加入无机盐-卡拉胶后脱水效应进一步减弱,渗透性进一步减弱。

In this paper,the study of Storage time dependence on water permeability and water exudation under compression in iota-carrageenan added agarose gels was measured by extrusion and osmosis.when carrageenan was added to agarose gel,the syneresis effect was weakened and the permeability was weakened too,after the inorganic saltcarrageenan was added to agarose gel,the syneresis effect was further weakened and the permeability was further weakened.
