【Gellan gum——Introduction】        Gellan gum, also known as Keke gum, is a high molecular linear polysaccharide. Gellan gum dry powder is beige, has no special taste and smell, and decomposes without melting at about 150°C. It has good heat and acid resistance and high stability to enzymes. It is insoluble in non-polar organic solvents and cold water, but it can be dispersed in water with a little stirring, and can be dissolved into a transparent solution after heating. After cooling, it can form a transparent and solid gel. Soluble in hot deionized water or a solution of low ionic strength in the presence of an integrant, the aqueous solution is neutral. application Gellan gum can be used as a thickener and stabilizer. Precautions for use: This product is easy to use. Although it is insoluble in cold water, it can be dispersed in water after a little stirring. It dissolves into a transparent solution when heated, and forms a transparent and solid gel after cooling. The dosage is small, usually only 1/3~1/2 of the dosage of agar and carrageenan, and the general dosage is 0.05% to form a gel (the usual dosage is 0.1%~0.3%).       The prepared gel is rich in juice, has good flavor release, and has a mouthfeel that melts in the mouth. It has good stability, resistance to acid hydrolysis and enzymolysis, and the gel made is very stable even under high-pressure cooking and baking conditions, and is also very stable in acidic products. good. Its texture is not changed by time and temperature during storage   Usage and dosage Due to the superior gel performance of gellan gum, it has gradually replaced the use of agar and carrageenan.
