Sodium Carboxymethyl Cellulose

Basic facts of the product:

Chemical formula: [C6H7O2(OH)2OCH2COONA]n

Ⅰ、Features
Our food grade CMC has a good evenness,high viscosity(even exceeding 2000 mPa.s),high degree of substitution (above 1.2),high purity(97%-99.5%),high acid resistance(AVR of Type FH9 above 0.9)and high saline resistance(soluble in any solution at any salt proportion,SVR in sea water or 4% Nacl solution above 1.0)

Our CMC has a fast solution rate and the dissolved solution has a good transpasency and good flowability.

Ⅱ、Applicable range and addition

  1. Lactate milk and sour drink: FH9,Fm9,FFH10;addition:2-5%.
  2. Flavour,comfit,sauce,and soup:FH9,Fm9,FFH9; addition:4-10%.
  3. Beer,wine,fresh fruit-keeping: addition:4-5%.
  4. Ice cream,instant noodle,bean milk,bread,biscuit and fast foods,etc:FH6,FVH6: addition:3-5%.

Ⅲ、Addition procedures

  1. Put water in a container and add CMC into this container under constant agitation.Then filter this solution by screen.
  2. If you want to add powder or granular ingredient(sugar),you should first dry-mix them with CMC and then dissolve them as method 1.
  3. If organic solvent is to be added to food,you should first disperse the CMC in this solvent and then disperse and dissolve it in water under constant agitation.

Ⅱ、Features
In addition to high degree of substitution,high viscosity and high purity,it is highly saline and temperature resistant due to it’s even substitution.Our CMC used as adhesive in toothpaste can resist cellulose and,thus it’s viscosity keeps constant.The paste compounded with it have a good luster,elasticity and won’t be subject to dehydration and coarsening.This CMC has good whiteness and transparency and is well dispersed in manufacturing process due to it’s thixotrpy with minimum mechanical wear.The paste made of it is very white,fine and smooth.
CMC has good fineness and at least 95% of it passes 100 mesh.It can be dissolved in a very short time and is stable in quality.
