Abstract
The invention discloses a preparation method of a deoxidizer for foods. The deoxidizer comprises 35-50wt% of iron powder, 3wt% or less of absorbent cotton, 5wt% or less of an inorganic salt, 5-9wt% of metal halide, 15-25wt% of active carbon, and the balance of water. The preparation method comprises the following steps: combining above raw materials according to above proportions, and stirring the iron powder, active carbon and the inorganic salt for at least 4min to guarantee full and uniform mixing; and adding the metal halide to water, scattering the above obtained iron powder, absorbent cotton and inorganic salt mixture to a solution obtained after the metal halide is dissolved, stirring, adding active carbon after uniformity, carrying out air drying, and bagging for preservation.
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 F22O3 (di-iron trioxide), absorbs oxygen with this process, thus reduce 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 preparation method of the food deoxidier that cost is lower.
For solving the problems of the technologies described above, the preparation method of food deoxidier of the present invention, is characterized in that comprising the following steps:
The first step, gets iron powder 35 ~ 50%, absorbent cotton≤3%, inorganic salts≤5%, metal halide 5 ~ 9%, active carbon 15 ~ 25%, water: surplus by weight percentage;
Iron powder, active carbon, inorganic salts are stirred, at least 4 minutes by second step together;
3rd step, is added to the water metal halide, makes dissolving;
4th step, the iron powder of the forward slip value be sprinkled into, absorbent cotton, inorganic salt mixt, then stir, make abundant dissolving.
5th step, adds active carbon, air-dry;
6th, envelope is preserved.
The advantage of this method:
Than conventional iron powder deoxidier, deoxidation speed is faster, passes through rational proportion, the reaction of catalysis iron powder, promotes deoxidizing capacity more fully thoroughly, and adds metal halide and the deoxidation of inorganic salts formation secondary, deoxidation timeliness is fully strengthened, and comprehensive deoxidizing capacity is greatly improved.
