Sol-gel transition of a mixture of gelatin and k-carrageenan

摘要

The characteristics of sol-gel transition of a mixture made by mixing two kinds of gelling agents of different nature, i.e. gelatin and carrageenan were examined. The sample solutions consisted of 3.00 wt/100 gelatin solution, 1.00 wt/100 k-carrageednan solution and 4.00 wt/100 mixed solution which was prepared by mixing the said gelatin and carrageenan solutions in the ratio 3:1. In the experiment, the optical rotation and the dynamic viscoelasticity were measured under the same temperature change program.
