Sodium carboxymethyl cellulose (CMC) as a food thickener
Sodium carboxymethyl cellulose (also known as: sodium carboxymethyl cellulose, carboxymethyl cellulose, CMC, Carboxymethyl, Cellulose Sodium, Sodium salt of Caboxy Methyl Cellulose) is the most widely used and the largest amount used in the world today types of cellulose. CMC-Na for short, is a c...Read more -
Dissolution and dispersion of CMC products
Mix CMC directly with water to make a pasty glue for later use. When configuring CMC glue, first add a certain amount of clean water into the batching tank with a stirring device, and when the stirring device is turned on, slowly and evenly sprinkle CMC into the batching tank, stirring continuous...Read more -
CMC application characteristics and process requirements in food
The use of CMC has many advantages over other food thickeners: 1. CMC is widely used in food and its characteristics (1) CMC has good stability In cold foods such as popsicles and ice cream, the use of CMC can control the formation of ice crystals, increase the expansion rate and maintain a unifo...Read more -
Answers to questions in the use of CMC
1. Question: How are low-viscosity, medium-viscosity, and high-viscosity differentiated from the structure, and will there be any difference in consistency? Reply: It is understood that the length of the molecular chain is different, or the molecular weight is different, and it is divided into lo...Read more -
Application example of CMC in acidic milk drink
1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....Read more -

Hydroxypropyl methyl cellulose ether for construction
Product characteristics of hydroxypropyl methylcellulose for construction Soluble in water and some organic solvents. Can be dissolved in cold water. Its maximum concentration only depends on the viscosity. The solubility changes with the viscosity. The lower the viscosity, the greater the solubi...Read more -
Proportion and Application of HPMC in Machine-blast Mortar
The mechanized construction of mortar has been tried and promoted for many years in China, but no substantial progress has been made. In addition to people’s skepticism about the subversive changes that mechanized construction will bring to traditional construction methods, the main reason ...Read more -
