CMC's use and contraindications:
1). The CMC(carboxy methyl cellulose) directly mixed with water into a paste glue formulated after backup. When configuring the CMC gum paste,
first in the ingredients added to the cylinder with a stirring device a certain amount of clean water, stirring device in the
open case, the CMC ingredients slowly and evenly spread to the cylinder, stirring constantly, making CMC and fully
integrated water, CMC can fully dissolved. When melted CMC, the reason for the spread evenly placed, and keep stirring,
the purpose is "to prevent the CMC and water meet, the occurrence of agglomerate, agglomeration, reducing the amount
of dissolved CMC issues" and to improve the dissolution rate of the CMC. Stirring time and CMC is completely dissolved in
the time are not consistent, the two concepts, in general, the time required for the stirring time is much shorter than the
CMC(carboxymethylcellulose) is completely dissolved, the time required for both, as the case may be. Determine the mixing time is based on: When
the CMC evenly dispersed in the water, there is no obvious big lumpy objects exist, they can stop stirring, let the CMC and
mutual penetration of water standing in the state, mutual integration. CMC is completely dissolved is determined based on
the time required for such aspects:
(1) CMC and water fully bonded, does not exist between the two solid - liquid separation;
(2) mixing paste that state was uniform, smooth surface;
(3) mixing the color close to transparent and colorless gum paste, paste that no granular object. CMC is from the tank into
the ingredient is mixed with water begins to CMC was completely dissolved, the time required between 10 to 20 hours.
2). The CMC first with white sugar and other dry ingredients, in the form of a dry mix, then dissolve into the water. When
operating, the first CMC first with white sugar and other dry ingredients in accordance with a certain proportion, on the
stainless steel blender, mixer off the roof, so that the material inside the mixer in a closed state. Next, open the mixer, the
CMC, and other materials sufficient mixing. Then, slowly mixing the CMC mixture evenly sprinkle the water-filled cylinder
ingredients, stirring constantly, subsequent operations can be carried out with reference to the first dissolution of the
methods described above.
3) When using the CMC in liquid or paste food, it is best to mix the materials were homogenized in order to obtain a more
delicate tissue status and stabilizing effect. Pressure and temperature homogenization employed, according to the material
characteristics and product quality requirements may be.
4) After the CMC formulated as an aqueous solution, preferably stored in ceramic, glass, plastic, wood and other types of
containers, should not use metal containers, especially iron, aluminum, copper container storage. Because, CMC solution
prolonged contact with the metal container, easily lead to deterioration and viscosity decreases. When the CMC solution
coexisting with lead, iron, tin, silver, aluminum, copper and certain metal species, a precipitate reaction, the solution
actually reduces the quantity and quality of the CMC. If not production needs, in the CMC aqueous solution, try not to mix
calcium, magnesium, salt and other substances. Because, when the aqueous solution of CMC and calcium, magnesium, salt
and other substances to coexist, will reduce the viscosity of CMC solution.
5) configured CMC solution, should be used as soon as possible. CMC solution if long term storage, will affect the adhesive
performance and stability of the CMC, will suffer against microorganisms and insects, rodents, thus affecting the health
quality of raw materials. However, some thickeners are starch hydrolysis of dextrin, modified starch and the like,
themselves non-toxic, but elevated blood sugar, and white sugar as easily, and may even lead to more severe glycemic
response. Elevated blood sugar but some consumers drink sugar-free yogurt, it was very likely caused by a thickening
agent, and not because of inherent lactose in milk composition, because the natural lactose and will not cause a rapid rise
in blood sugar. Therefore, before purchasing sugar-free products, be sure to see the list of ingredients, beware of the
impact caused by thickening of the blood.
