La description
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.
