Can Calcium Chloride Desiccant Be Used As A Food Desiccant
Nov 28, 2018

Calcium chloride desiccant (CaCl2) is white powder, granular, flake, and block. Calcium chloride has a high solubility in water. At 0 ° C, 100 g of water can dissolve 59.5 g of calcium chloride. At 100 ° C, 100 g of water can dissolve and dissolve 159 g of calcium chloride. It can form hydrates containing 1, 2, 4, and 6 crystal waters, and their temperature ranges are: CaCl2•6H2O below 29 °C; CaCl2•4H2O, 29-45 °C; CaCl2•2H2O, 45-175 °C; CaCl2•H2O, above 200 °C.


Calcium chloride desiccant (CaCl2) is available in both food grade and industrial grade. Food grade calcium chloride desiccant meets food grade requirements from hygienic standards and can be used as a food desiccant. However, our manufacturers generally do not recommend chlorination. Calcium desiccants are used in foods, mainly because of safety issues. When the child was accidentally injured by the desiccant, there was media reports that the internal substance of the calcium chloride desiccant was powdery. If the child teared the calcium chloride desiccant package, the calcium chloride powder inside would easily enter the eye, causing eyelid swelling and cornea. And white burns on the conjunctiva and other symptoms, the light cures the corneal leukoplakia, affecting vision, and causing blindness. At the same time, news of children eating desiccant has often been reported, although calcium chloride can be used for food additives, but calcium chloride desiccant is not directly edible.

It can be used as a food desiccant with a transparent silica gel desiccant and a plant fiber having water absorption after processing. Chunwang recommends a transparent silica gel desiccant because it is easy to manufacture and low in cost. The main component of SiO2 is the same as the sand in the river and the main components of the glass in the house. The ingredients are very safe, non-toxic, odorless, non-corrosive and non-polluting. It is characterized by a FDA-approved desiccant that can be directly used in foods and medicines. Even if the desiccant is eaten by a child, it will not be absorbed by the body and will be excreted.
