Abstract
The invention discloses a deoxidizer for food fresh keeping. The deoxidizer comprises, by weight, 10 parts of iron, 2.5-3 parts of active carbon, 2.1-4.5 parts of metal halide, 1.5-1.9 parts of a swelling agent, 0.2-0.5 parts of pumice, and 0.5-1.2 parts of water. The deoxidizer has the following advantages: the active carbon and the metal halide are used to catalyze, so the deoxidization effect of reduction iron powder is substantially improved; the swelling agent and the pumice are added, so the catalysis effect of the metal halide is still kept in high-temperature wet environment, thereby the full oxidation reaction of the iron powder is guaranteed, and the timeliness and the deoxidization amount of the deoxidizer are integrally improved; and material selected in the invention are cheap and general products, so the cost is low.
Description
Technical field
The invention belongs to food storage anti-corrosive fresh-keeping oxygen scavenger technical field, relate to a kind of food fresh-keeping oxygen scavenger.
Background technology
Oxygen scavenger, has another name called deoxidier.Be widely used in biochemical industry, the industry manufacture field such as pharmaceuticals, food, smelting.In food storage, the breeding of oxygen meeting cooperating microorganisms germ, and cause oil food to rot, or because making food fade with food material surface oxidation reaction, so the free oxygen removed in air is the important method of preserving food.Be generally used for food storage, the oxygen scavenger of Keep the quality and freshness is the inorganic oxygen scavenger of iron system, its principles of chemistry are just give birth to oxidation reaction by iron and oxygen to generate Fe
2o
3thus oxygen depleted.But, conventional iron powder deoxidier because of its iron be need to complete under the effect of water, so need high moisturizing environment, and reaction rate is slow, in order to solve Similar Problems, common iron system oxidant is based on iron powder, auxiliary interpolation metal halide such as calcium chloride etc.But problem new is thus that calcium chloride adds can cause deliquescence too much, forms secondary pollution.Chinese patent (publication number: CN103653185A) discloses a kind of food moisture-proof deoxidier, and a kind of preferred ingredient is wherein: iron powder 100 parts, 10 parts, calcium chloride, active carbon 10 parts and auxiliary material 30 parts; Described auxiliary material is attapulgite and montmorillonite, and mass ratio is 6:4.The program has made improvement for the use problem of calcium chloride, by adding the Composition Control of concavo-convex stone rod, keeps the negative balance to high humidity environment.But the program still have employed the not low sodium chloride of ratio, and deliquescence phenomenon still exists, another problem of the program is that concavo-convex stone rod is the chemical material that a kind of price is partially expensive, and its market price is about 400 yuan/kilogram.Cause the inevitable cost intensive of this product, be unfavorable for marketing.
Summary of the invention
For the defect existed in above technology, the present invention, by rational selection and proportioning, provides one can keep the efficient moisture-proof simultaneously of oxidation of iron powder effect, but food fresh-keeping oxygen scavenger with low cost.
For solving the problems of the technologies described above, food fresh-keeping oxygen scavenger of the present invention consists of the following composition, and counts by weight, iron: 10 parts, active carbon: 2.5 ~ 3 parts, metal halide: 2.1 ~ 4.5 parts, swelling agent: 1.5 ~ 1.9 parts, pumice: 0.2 ~ 0.5 part, water: 0.5 ~ 1.2 part.
Wherein, described food fresh-keeping oxygen scavenger, is characterized in that described iron powder is reduced iron powder.
Described food fresh-keeping oxygen scavenger, is characterized in that described active carbon is cocoanut active charcoal.
Described food fresh-keeping oxygen scavenger, is characterized in that described metal halide is sodium bromide.
Described food fresh-keeping oxygen scavenger, is characterized in that described swelling agent is calcium bentonite.
As a further improvement on the present invention, described food fresh-keeping oxygen scavenger, counts by weight, has following one-tenth to be grouped into---iron: 10 parts, active carbon: 2.6 parts, metal halide: 2.5 parts, swelling agent: 1.68 parts, pumice: 0.21 part, water: 0.67 part.
Advantage of the present invention has: by the component of rational proportion active carbon, and the composition of rational proportion metal halide, catalysis iron powder oxidation reaction, the deaerating effect of reduced iron powder is significantly improved, meanwhile, swelling agent is added, pumice, make the catalytic effect that still can keep metal halide under high temperature, wet environment, ensure that the fully oxidized reaction of iron powder with this.Integral lifting oxygen scavenger ageing and except oxygen amount.And selected materials all belongs to known general chemical material, with low cost.
