Can silica gel be used as a food desiccant?

Food desiccant is a very common thing. Only in this way can food prevent any rotting. However, children should never be exposed to this substance, otherwise it will cause great harm to their bodies and may also hurt the baby's eyes. Silica gel can also be used as a food desiccant, and this desiccant can be used in the sugar we usually eat.

Quicklime desiccant

The main component of quicklime desiccant is calcium oxide, and its water absorption capacity is achieved through chemical reaction, so the water absorption is irreversible. Regardless of the humidity of the external environment, it can maintain a moisture absorption capacity greater than 35% of its own weight, is more suitable for low temperature storage, has excellent drying and moisture absorption effect, and the price is

Lower. It can be widely used in food, clothing, tea, leather, shoemaking, electrical appliances and other industries. This type of desiccant is currently most commonly used in "snow cakes". However, quicklime desiccant is often used because of its strong alkaline corrosiveness and often causes harm to the eyes of children or the elderly. It has now been gradually phased out.

Silica gel desiccant

This desiccant is different varieties of silica gel packaged in small moisture-permeable bags. The main raw material, silica gel, is a highly microporous hydrated silicon dioxide that is non-toxic, tasteless, odorless, chemically stable, and has strong hygroscopic properties. Therefore, it is widely used in the storage and transportation of instruments, meters, equipment, leather, bags, shoes, textiles, food, medicines, etc. to control the relative humidity of the environment and prevent the items from moisture, mildew and rust. For example, it is used in xylitol, and it is also the only desiccant approved by the European Union.

Montmorillonite desiccant

This desiccant is made of pure natural raw material bentonite, which is green, environmentally friendly, non-toxic and odorless, and harmless to the human body. It has good adsorption performance at room temperature and normal humidity, has adsorption activity, and has the effects of static dehumidification and odor removal. It not only has a fast adsorption speed and high adsorption capacity, but is also non-toxic, odorless, non-contact corrosive, and has no environmental pollution. It is especially used in food packaging and is harmless to the human body. Scope of application: Widely used in products that cannot be sealed with oil or gas, such as optical instruments, electronic products, medical care, food packaging, and dry air sealing of military and civilian products.

Calcium chloride desiccant

The main raw material of calcium chloride desiccant is calcium chloride, which is made of high-quality calcium carbonate and hydrochloric acid and refined through reaction synthesis, filtration, evaporation concentration, drying and other process. White porous block, granular or honeycomb solid. It tastes slightly bitter and has no odor. The aqueous solution is colorless. It is mainly used as a raw material for the production of various other calcium salts in inorganic chemicals; it is also used as a gas desiccant and a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins. In the food industry, it is used as a calcium fortifier, curing agent, chelating agent, desiccant, etc.

Fiber desiccant

Fiber desiccant is made from pure natural plant fiber through a special process. Among them, the coated fiber desiccant sheet is especially convenient and practical, and does not take up space. Its moisture absorption capacity reaches 100% of its own weight, which is unmatched by ordinary desiccants. In addition, the product is safe, hygienic and reasonably priced, making it an ideal choice for many biological, health foods and medicines.
