Abstract:
Gellan gum is a promising microbial extracellular polysaccharide in recent years, which has excellent characteristics such as low dosage, high transparency, acid resistance, high temperature resistance, enzyme resistance and good compatibility, and has broad application prospects in food, pharmaceutical and chemical industries.
At present, the carbon source in the fermentation medium for industrial production of gellan gum is sucrose or glucose, which is more expensive compared with common starch and molasses, increasing the production cost and leading to higher final selling price, therefore, using molasses, starch and even cellulose as primary raw materials is the development trend.
