How To Avoide The Decomposition Of Carboxymethyl Cellulose-CMC
- Jan 25, 2018 -

We have learned that the conventional carboxymethyl cellulose (CMC) is affected by temperature obviously. The CMC is not stable under the high temperature or high salt environment if not the special types. In addition to this, the solution will become the diute solution after placing a period of time. The stability of it also affected by the microbes on some degree besides the various factors before.

The carboxymethyl cellulose(CMC) can be modification by replacing with different substituent groups (alkyl or hydroxyl alkyl), its antimicrobial ability will improve. 

Scientific research found that the water-soluble carboxymethyl cellulose(CMC) derivatives, the degree of substitution is an important factor affecting the enzymatic resistance. When the degree of substitution is higher than 1, sodium carboxymethyl cellulose has the ability of microorganism erosion resistance, and the higher the degree of substitution the better of the uniformity.

High degree of substitution carboxymethyl cellulose(CMC) has a stronger antimicrobial ability and antienzyme ability. In the food field, it almost do not have any change after intestinal digestion. From this we can know that it is stable in the biochemical and enzyme system. This makes the application of sodium carboxymethyl cellulose in food industry has a new understanding.
