Abstract
The invention discloses a deoxidizer for foodstuff. The deoxidizer is characterized in that: the deoxidizer comprises the following components: 35-50 weight% of iron, 15-25 weight% of active carbon, 5-9 weight% of metal halide, less than or equal to 5 weight% of inorganic salt, less than or equal to 3 weight% of absorbent cotton, and the balance being water. The deoxidizer for foodstuff is advantageous in that: compared with conventional iron powder deoxidizer, the deoxidizer has a faster deoxidation speed; reasonable preparation is used for realizing full and complete catalysis of reaction of iron powder and improving deoxidation capability; metal halide and inorganic salt are added for carrying out secondary deoxidation, so that time efficiency of deoxidation is fully improved, and comprehensive deoxidation capability is greatly enhanced.
Description
Technical field
The invention belongs to food deoxidier technical field, relate to a kind of food deoxidier.
Background technology
Oxygen is ubiquitous a kind of gas in the Nature, and is the required of the mankind and various biological existence.Meanwhile, oxygen is also the necessary condition of various bacterium, microbial reproduction existence.Especially in airtight container, easier grow because oxygen content is plentiful various disease and pest microorganism make storage environment destroy.Deoxidier, has another name called oxygen scavenger, is a kind of product that can reduce oxygen content in certain space.Usually, deoxidier is made up of iron powder, utilizes the oxygen reaction in reduced iron and air to produce F2
2o
3(di-iron trioxide), absorbs oxygen with this process, thus reduces oxygen concentration in gas.The most of deoxidier used in the market is all based on these principles of chemistry.But iron powder deoxidation has a common fault, that is exactly that reaction rate is lower, and deoxidation speed is partially slow.Chinese patent (publication number is CN103478247A) discloses a kind of iron series deoxidizers, wherein accelerate the speed of iron oxidation reaction by adding active carbon thus reach raising deoxidation effect, have employed polyacrylic super absorbent resin to absorb the moisture of evaporation, control stability simultaneously.But the problem of this product has 2 points: 1. iron powder ratio is up to 60%, and active carbon ratio is too low, cannot complete abundant catalytic action, causes iron powder all can not participate in oxidation fast.2. although polyacrylic super absorbent resin water imbibition is very excellent, in its water absorption course, can phenomenon be expanded, be unfavorable for that envelope is preserved.
Summary of the invention
For the defect existed in above technology, the invention provides one and can accelerate deoxidation speed, improve deoxidizing capacity, and more convenient to use, the food deoxidier that cost is lower.
For solving the problems of the technologies described above, food deoxidier of the present invention consists of the following composition (counting by weight percentage)---iron: 35 ~ 50%, active carbon: 15 ~ 25%, metal halide: 5 ~ 9%, inorganic salts :≤5%, absorbent cotton :≤3%, and the water of surplus.
Described iron powder is 80-120 object reduced iron powder.
Described metal halide is sodium chloride.
Described inorganic salts are sodium dithionite.
As a further improvement on the present invention, described food deoxidier, by weight percentage, has following one-tenth to be grouped into---iron: 47%, and active carbon: 17.5%, metal halide: 9%, inorganic salts:
3.2%, absorbent cotton: 2.2%, water: 21.1%.
Described iron powder is 100 object reduced iron powders.
Described metal halide is sodium chloride.
Described inorganic salts are sodium dithionite.
Advantage of the present invention has: than conventional iron powder deoxidier, deoxidation speed is faster, pass through rational proportion, catalysis iron powder reaction more fully thoroughly, promote deoxidizing capacity, and add metal halide and the deoxidation of inorganic salts formation secondary, make deoxidation timeliness fully strengthen, comprehensive deoxidizing capacity is greatly improved.
