1. Mix sodium carboxymethyl cellulose with water directly to make a paste glue and set aside.
When configuring sodium carboxymethyl cellulose paste, first add a certain amount of clean water into the batching tank with a stirring device, and sprinkle sodium carboxymethyl cellulose slowly and evenly on the In the batching tank, keep stirring, so that the sodium carboxymethyl cellulose and water are completely fused, and the sodium carboxymethyl cellulose can be fully dissolved. When dissolving sodium carboxymethyl cellulose, the reason why it should be evenly sprinkled and stirred continuously is to “prevent clumping and agglomeration when sodium carboxymethyl cellulose meets water, and reduce the quality of carboxymethyl cellulose. Dissolution of sodium”, and increase the dissolution rate of sodium carboxymethylcellulose. The stirring time is not consistent with the complete dissolution time of sodium carboxymethyl cellulose. They are two concepts. Generally speaking, the stirring time is much shorter than the time required for complete dissolution of sodium carboxymethyl cellulose. The time required depends on the specific situation. The basis for determining the stirring time is: when the sodium carboxymethyl cellulose is uniformly dispersed in water and there is no obvious large agglomerate, the stirring can be stopped, and the sodium carboxymethyl cellulose and water are allowed to stand still. Infiltrate and merge with each other. The basis for determining the time required for sodium carboxymethylcellulose to completely dissolve is as follows:
(1) Sodium carboxymethyl cellulose and water are completely bonded, and there is no solid-liquid separation between the two;
(2) The mixed paste is in a uniform state, and the surface is flat and smooth;
(3) The color of the mixed paste is close to colorless and transparent, and there are no granular objects in the paste. From the time when the sodium carboxymethyl cellulose is put into the batching tank and mixed with water until the sodium carboxymethyl cellulose is completely dissolved, the required time is between 10 and 20 hours.
2. Mix sodium carboxymethyl cellulose with dry raw materials such as white sugar in a dry form, and then put it into water to dissolve.
During operation, first put sodium carboxymethyl cellulose and white granulated sugar and other dry raw materials in a stainless steel mixer according to a certain ratio, close the top cover of the mixer, and keep the materials in the mixer in an airtight state. Then, turn on the mixer, fully mix the sodium carboxymethyl cellulose and other raw materials. Then, slowly and evenly scatter the stirred sodium carboxymethyl cellulose mixture into the batching tank equipped with water, and keep stirring, and the following operations can be carried out with reference to the first dissolution method mentioned above.
3. When using sodium carboxymethyl cellulose in liquid or slurry food, it is best to homogenize the mixed material in order to obtain a more delicate tissue state and stabilization effect.
The pressure and temperature used for homogenization should be determined according to the characteristics of the material and the quality requirements of the product.
4. After the sodium carboxymethyl cellulose is prepared into an aqueous solution, it is best to store it in ceramic, glass, plastic, wooden and other types of containers. Metal containers, especially iron, aluminum, and copper containers, are not suitable for storage.
Because if the sodium carboxymethyl cellulose aqueous solution is in contact with the metal container for a long time, it is easy to cause deterioration and viscosity reduction. When the sodium carboxymethyl cellulose aqueous solution coexists with lead, iron, tin, silver, aluminum, copper and certain metal substances, a precipitation reaction will occur, reducing the actual quantity and quality of the sodium carboxymethyl cellulose in the solution. If it is not necessary for production, try not to mix calcium, magnesium, salt and other substances in the aqueous solution of sodium carboxymethyl cellulose. Because, when the sodium carboxymethyl cellulose aqueous solution coexists with calcium, magnesium, salt and other substances, the viscosity of the sodium carboxymethyl cellulose solution will be reduced.
5. The prepared sodium carboxymethyl cellulose aqueous solution should be used up as soon as possible.
If the sodium carboxymethyl cellulose aqueous solution is stored for a long time, it will not only affect the adhesive performance and stability of sodium carboxymethyl cellulose, but also be attacked by microorganisms and pests, thus affecting the hygienic quality of raw materials. However, some thickeners are dextrins and modified starches produced by starch hydrolysis. They are non-toxic and harmless, but they are as easy to raise blood sugar as white sugar, and may even cause more severe blood sugar reactions. Some consumers’ blood sugar rises after drinking sugar-free yogurt, which is likely to be caused by thickeners, not because of the inherent lactose content in milk, because natural lactose does not cause a rapid rise in blood sugar. Therefore, before buying sugar-free products, be sure to read the ingredient list and beware of the impact of thickeners on blood sugar.
