1. Is there a difference between desiccant and deoxidizer for food
1. Food desiccant: the main materials are calcium oxide and silica gel.
2. Deoxidizer: The material is mainly a deoxidizer based on inorganic matrix, such as reduced iron powder; it is based on organic matrix, such as enzymes , ascorbic acid, oleic acid, etc.
1. Food desiccant: Substances that can remove moisture from humid substances, such as calcium sulfate and calcium chloride, combine with water to form hydrates for drying. .
2. Deoxidizer: an additive that can absorb oxygen and slow down the oxidation of food.
1. Food desiccant: widely used in the storage and storage of instruments, instruments, equipment, leather, bags, footwear, textiles, food, medicines, etc. Control the relative humidity of the environment during transportation to prevent items from getting damp, mildew and rust.
2. Deoxidizer: Deoxidizer is not only used to maintain food quality, but also used in grains, feed, medicines, clothing, fur, precision instruments and other items preservation, rust prevention, etc.
2. What are the ingredients of food desiccant
The main component of quicklime desiccant is calcium oxide. Its water absorption capacity is achieved through chemical reaction, so water absorption is irreversible. Widely used in food, clothing, tea, leather, shoemaking, electrical appliances and other industries.
This desiccant is a different type of silica gel that comes in a moisture-permeable bag. The main raw material silica gel is highly microporous hydrated silica, which is non-toxic, tasteless, odorless, chemically stable and highly hygroscopic. Therefore, it is widely used in the storage and transportation of instruments, instruments, equipment, leather, bags, shoes, textiles, food, medicines, etc. to control the relative humidity of the environment and prevent items from getting damp, mildew and deterioration. rust.
The desiccant uses bentonite, a pure natural raw material, which is environmentally friendly, non-toxic, odorless and harmless to the human body. It has good adsorption performance at normal temperature and normal humidity, and has adsorption activity, static dehumidification and odor removal. It is widely used in products that cannot be sealed with oil or gas phase, such as dry gas sealing of optical instruments, electronic products, medical care, food packaging, military and civilian products.
3. Is the desiccant in food packaging a sealed bag?
1. The desiccant in food packaging is usually not a sealed bag. Desiccant usually uses non-woven fabrics or OPP plastic films with good air permeability as outer packaging instead of sealed bags.
2. It should be noted that the desiccant needs to be placed in a sealed package to better exert its moisture-proof effect. If the food packaging is not sealed, the desiccant will continuously absorb moisture from the air entering from the outside. Once the moisture absorption is saturated, the dehumidification effect will be lost.
4. Does the country have regulations on desiccants in food bags
Food desiccants are generally non-toxic, odorless, non-contact corrosive, and non-environmental pollution. Food desiccant is used to reduce the humidity in food bags and prevent food from deteriorating. Therefore, it cannot be taken into account in food quality.
5. What are food desiccants
1. Quick lime drying Agent, composed of quicklime, has significant hygroscopic effect, low price, and is widely used in the food industry.
2. Silica gel desiccant, high microporous structure hydrated silica, stable chemical properties and strong hygroscopicity.
3. Calcium chloride desiccant, white porous block or honeycomb solid, slightly bitter and odorless, used as chelating agent, desiccant, etc. in the food industry.
6. What are the main ingredients of food desiccant
1 , quicklime (calcium oxide), silica gel, montmorillonite, calcium chloride, fiber desiccant, etc.
2. Quicklime (calcium oxide) is white particles or lumps, which expand and heat when exposed to water and cannot be put into bottles and jars; silica gel is transparent bead particles. It is non-toxic, tasteless and environmentally friendly; montmorillonite is a natural mineral, gray or brown, environmentally friendly and has no impact on the environment; calcium chloride is a white porous block, granular or honeycomb solid; fiber desiccant is made of pure natural plant fibers. Made with special technology.
