Carboxymethylcellulose (CMC for short) is a commonly used food additive, and its sodium salt (sodium carboxymethylcellulose) is often used as a thickener and paste.


Dissolution method


Mix CMC directly with water to prepare a paste glue solution and set aside. When configuring CMC paste, first add clean water to the batching tank with a stirring device. With the stirring device turned on, slowly and evenly spread CMC into the batching tank and stir continuously to fuse CMC and water. , CMC can be fully dissolved. When dissolving CMC, the reason why it is necessary to spread it evenly and stir continuously is "to prevent the problems of agglomeration, agglomeration, and reduction of the amount of CMC dissolved when CMC meets water" and to increase the dissolution speed of CMC. The stirring time and the CMC melting time are not consistent. They are two concepts. Generally speaking, the stirring time is much shorter than the time required for CMC to melt. The time required for both depends on the specific situation.


The basis for determining the stirring time is: when the CMC is evenly dispersed in the water and no obvious large lumps exist, the stirring can be stopped and the CMC and water can penetrate and merge with each other while standing.
