As a widely used chemical reagent, sodium carboxymethyl cellulose is susceptible to the influence of some external environment and temperature, which makes its chemical properties reversely changed, at the same time the bacteria and microorganisms in it will also affect the stability of CMC-Na, resulting in deterioration.
CMC-Na is obviously affected by temperature. If it is not a special grade of CMC-Na, it is unstable in high temperature or high-salt environment. In addition, many users respond that the solution of CMC will become thinner after a period of time. In addition to being affected by previous various factors , its stability will also be affected by bacterial and microorganisms to some extent.
CMC-Na is modified with different substituent groups (alkyl or hydroxyalkyl), and its antimicrobial ability will be improved. According to research, , the degree of substitution of the derivatives of water-soluble sodium carboxymethyl cellulose is an important reason for affecting the enzyme resistance. If the degree of substitution is higher than 1, it has the ability to resist microbial erosion. Furthermore, the higher the degree of substitution, the better its uniformity. So the ability to resist microorganisms is stronger.
Sodium carboxymethyl cellulose with a high degree of substitution has stronger antimicrobial ability and stronger anti-enzyme ability. In terms of food application, CMC-Na hardly changes after intestinal digestion, which shows that it is stable in biochemical and enzyme systems. This makes the application of CMC-Na in food has a new understanding.
Once sodium carboxymethyl cellulose deteriorates, its performance and function will change, and this product will not be suitable to be used. In order to avoid the deterioration of CMC-Na, it should be placed in the storing environment and the temperature is suitable. Within the specified conditions, the higher the degree of substitution of CMC, the stronger its resistance to deterioration and the more stable its performance.
