Study on the Combined System of Biological Gellan Gum - Waxy Maize Starch

摘要

Gellan gum was known as one of the most successful modes of exocellular polysaccharide of fermented of the 20th century. The combined system of gellan gum and waxy maize starch was studied in this article. The research showed that there was certain cooperative effect between gellan gum and waxy maize starch and their viscosity increased along with the concentration increasing. The viscosity of combined system changed at different temperature, pH, ion concentration, shearing time and speed was also focused. Results showed that the combined system had such properties as temperature hysteresis, shear thinning and viscosity increasing with potassium ion. The above results have guiding significance on the development of fermentation polysaccharide products.
