gellan gum

Descripción del producto

Product presentation Gellan gum is the extra-cellular polysaccharide produced by the Gram-negative bacteria-psudomonas elodea, which has been allowed to be food additive by International Food Legal *****, it has also been allowed to be the food additive in our country in ***6. Gellan gum is a kind of microbial polysaccharide which is made up of two β-D-Glucose, one β-D-Glucuronic Acid, one α-L-Rhamnose，and it is one of the best microbial polysaccharide ***** gum has been used as suspe—nsion agent, thickener, gelling agent, clarifier, emulsifier, stabilizer, film former, lubricant, tissue cu*-lture medium, etc in more than *0 fields, such as food, cosmetics, washing, petroleum explorati-on, medical, ceramics, etc. Gellan gum has some traits as follows:1.Little usage amount;***** heat stability and resisting acid;***** releasing scent;***** gel transparentation;5.adjustable elasticity and hardness;***** compatibility. It will take on the character of pseudoplastic fluid when Gellan gum is used about 0.*1%*0.*4%, and it can shape clear and transparent gum when the usage amount is above 0.*5%.The intensity of gum which is generated by the usage amount of 0.*5 percent of Gellan gum is the same with that which is generated by the usage amount of 1.5 percent of Agaragar and 1 percent of ***** usural usage amount of Gellan gum, which is the one fifth to one twice of that of the Ggaragar and Carrageenin, is 0.1%*0.3%. Product category Our company can produce two kinds of Gellan gum: High-acyl Gellan gum(Natural Gellan gum) and Low-acyl Gellan gum. It is the main difference of this two gum as follows: The gel which is formed by High-acyl Gellan gum is soft and elastic, and has a good adhesive ability; Low-acyl Gellan gum is a product which can be gotten after the high-acyl Gellan gum is specially ***** gel which is formed by low-acyl Gellan gum is hard, fragile, high-intensity, and the gelling temperature is lower. Low-acyl Gellan gum is mostly used in industry. This two Gellan gum above can be mixed according to different proportion, and more high-acyl Gellan gum is , better the spring and keeping water of the mixed gum is, and the gelling temperature of this mixed gum is higher than low-acyl Gellan gum. This two kinds of Gellan gum can be respectively used in food and medical. Character Color and shape Light yellow powder Smell No special taste and smell Gelling temperature *0～*0 centi degree Decomposing temperature It will be decomposed without melting in **0 centi degree. Gel melting temperature *5～**0 centi degree PH range 3.5～8.0 Gelling condition Heating;enough ***** amount of cation and intensity of gel is samotenious in some range.
