Deoxidizer is an additive that can absorb oxygen and slow down the oxidation of food. Deoxidizer can effectively inhibit the growth of mold and aerobic bacteria, prolong the shelf life of food, prevent the rancidity of the oil, prevent oxidative browning of the meat and prevent the loss of vitamins in the food.
Deoxidizer commonly used reaction principle iron oxide (iron), enzyme oxidation (enzyme), ascorbic acid oxidation, light-sensitive dye oxidation. Most of the deoxidizers currently used are based on iron oxide oxidation. This iron-based deoxidizer can be made into a bag, placed in the package, so that the oxygen concentration dropped to 0.01%. General requirements lg iron powder and 300mL of oxygen reaction, when used according to the amount of oxygen remaining after packaging and packaging film oxygen permeability choose the appropriate amount. Applied products include sweets, dried seafood snacks, cooked meats, rice cakes, pasta, cheese, dried vegetables. In addition to bagged deoxidizer, plastic tags or various cards containing active iron powder are also inserted into the package.
In addition to iron-based deoxidizer, enzyme deoxidizer is also widely used. Enzyme-based deoxidizers are sensitive to changes in pH, Aw, salt content, temperature and other factors and require water for the reaction. Therefore, they are ineffective in foods with low moisture content. However, in bottled beer or liquor, this deoxidizer can be directly made into a pouch, placed in the cap. In addition, enzymes can also be immobilized on polypropylene or polyethylene films. There is also a class of deoxidizer is a light-sensitive dye deoxidizer, this deoxy technology is in the transparent top of the packaging bag sealed ethyl ethyl cellulose film (internal dissolved dye and singlet oxygen singlet oxygen receptor), when When the packaging film is exposed to light of a suitable wavelength, the excited dye molecules will sensitize oxygen molecules into the packaging film in the environment to singlet oxygen, which is consumed by reaction with the acceptor molecule. 02TM in Australia is designed for a range of plastic packaging materials where the reactive components are activated by UV or high energy and are therefore suitable for processing films, sheets and coatings. Tests on the 02TM contained in the flexible layer show that the mold can be inhibited without carbon dioxide and can even prevent the ham from fading under visible light.
Deoxidizer can be used alone, can also be combined with the atmosphere package. In practice, more use of atmosphere packaging to remove most of the oxygen, then use a smaller amount of deoxidizer removal of residual oxygen in the package approach.
Casting deoxidizer main component of iron silicide, the main role is to remove the iron oxide in the molten iron to produce non-metallic products, drift to the surface of molten iron, slag residue plus scrape, you can get pure molten iron.
Deoxidizer as a new food preservation materials, has its unique advantages. It is packed in the same container as the food, and the deoxidizer absorbs the oxygen in the container to make the container anaerobic and the food is preserved. However, the raw material of the deoxidizer must have the side effect of stable reaction, no strange smell and no harmful gas generation, and will be harmless to the human body in case of eating by mistake. Deoxidizer generally iron powder as a basic raw material, used in general food, to maintain food quality and extend shelf life, use in healthy foods to prevent oxidation of oil, to prevent discoloration and maintain nutrients. Foreign deoxidizer has been widely used in wet bread flour, wet noodles, wet vermicelli, wet dim sum, semi-dried fish products and other foods. At present, in addition to the form of deoxidizer bag, there are caps. Bags for bags of food, caps are used for bottles, cans and other containers. In recent years, with the development of the food industry and the improvement of packaging materials, deoxidizer has been paid more and more attention in China, and the application is also more and more widely.
