Abstract
The fresh-keeping agent comprises (by weight portion) 15-25 portions of nanometer silicone base oxide (NM.SiO2-x), 40-50 portions of cast iron powder, 15-25 portions of natron, 4-8 portions of active carbon and 7-13 portions of salt, in which the nanometer silicone base oxide possesses strong adsorption and strong catalysis property, not only can adsorb oxygen to make structure stable, but also possesses strong catalysis of oxidation reaction of iron, so that it can greatly raise its deoxidation effect. Said invented formula has no need of adding water, and can obtain quick and effective effect of removing oxygen.
Description
The invention belongs to food additives, relate in particular to a kind of deoxidation antistaling agent.
Food is subject to oxygen harm in storage, fortune process.When packing, puts into food deoxidation antistaling agent, can remove free oxygen and the molten oxygen of depositing in the sealing system, food is under anaerobic or the hypoxia, can effectively suppress the quality deterioration that causes because of oxidation, keep the original color of food, prevent the growth of insect pest, mould, keep nutritional labeling, prolong preservation term.
Traditional oxygen scavenger kind is more, has following several: form with iron powder, form, form with ammonium chloride and copper powder with active carbon and zinc, aluminium, with dithionite be that matrix is formed and with enzymolysis glucose serve as main form etc.These oxygen scavengers show the defective aspect following three in varying degrees in application: (1), deoxygenation are renderd a service low.The deoxygenation of at present commercially available several oxygen scavenger products is renderd a service between 45～55mlO
2Between/the g, the oxygen in being equivalent to remove between 1 lift-off needs oxygen scavenger 3.8～4.7 grams.(2), accessory substance is arranged in the deoxygenation course of reaction, can produce certain harmful effect to food.As the most frequently used iron is oxygen scavenger, with the reaction of oxygen in produce hydrogen, and hydrogen is very active gas, influences the preservation of food.(3), use inconvenience.Some oxygen scavenger must add water in use or at water environment the oxygen uptake reaction could take place, and the amount of water difference, and oxygen absorbed is also different, has caused very big difficulty to practical application.As the cast iron powder oxygen scavenger that uses in the present grain depot, need elder generation is through the vapours activation and remain on saturation state, and its deoxygenation is renderd a service but very low.This not only uses inconvenience, and the waste resource, the increase expense.
The objective of the invention is to overcome the defective of above-mentioned oxygen scavenger, and a kind of novel deoxidation antistaling agent is provided, this deoxidation antistaling agent has efficiently, safety, advantage easily.
Deoxidation antistaling agent is characterized in that: by nano silicon-based oxide (NM.SiO
2-X), cast iron powder, washing soda, active carbon and salt mixes, by weight, the proportioning of each material is as follows:
15～25 parts of nano silicon-based oxides
40～50 parts of cast iron powders
15～25 parts of washing sodas
4～8 parts of active carbons
7～13 parts of salt.
Each material is powdery, and fineness is being as the criterion by 80 eye mesh screens.
With the contrast of prior art, the present invention has introduced the up-to-date scientific and technological achievement in the present world---nano material first in oxygen scavenger: nano silicon-based oxide (NM.SiO
2-X).This material is unformed white powder, is a kind of nontoxic, tasteless Inorganic Non-metallic Materials.Its particle size is minimum, and only about 10nm, specific area is very big, about 64m
2/ g, the surface exists undersaturated residual bond and numerous hydroxyl; Depart from stable silica structure because of oxygen debt in the molecule, so molecular formula SiO
2-XIn " X " arranged.These unique physical and chemical properties make it have the feature of strong absorption and strong catalysis.In this product, at first, this material needs oxygen uptake on the one hand so that structure tends towards stability, and the oxidation reaction to iron has powerful catalytic action on the other hand, thereby the deoxygenation that has promoted this product is greatly renderd a service.After measured, the deoxygenation of this product is renderd a service and is 81.7mlO
2/ g is 1.5～1.8 times of traditional oxygen scavenger.Secondly, this material surface has unsaturated residual bond and hydroxyl, and is extremely strong to the affinity of hydrogen.This product is surveyed in to the application test of food fresh keeping and is shown that also no hydrogen detects.In addition, the proprietary prescription of this product need not to add water, can reach deaerating effect fast and effectively.
By as seen above-mentioned, this product has been different from traditional oxygen scavenger, not only has deoxygenation performance efficiently, thereby and because common iron has been avoided in the introducing of nano material is the harmful effect of the hydrogen that produces of oxygen scavenger to food quality, strengthened preservation to food, and easy to use.
Describe in detail below in conjunction with embodiment.
Embodiment one
By above-mentioned requirements, take by weighing following material:
Nano silicon-based oxide 2g
Cast iron powder 4g
Washing soda 2.5g
Active carbon 0.8g
Salt 0.7g
Altogether 10g mixed 5 minutes, packed by every bag 2g with the paper gas permeable material, place in the gas barrier bag film of 1 liter of internal volume to seal, and the detection of bleeding through 24 hours, the deoxygenation amount is 123.8ml, is equal to 62mlO
2/ g.
Embodiment two
Press the method among the embodiment one, choose orthogonal table L
16(4
5) carry out orthogonal test, triplicate, analyze best proportioning by statistics and be:
16 parts of nano silicon-based oxides
41 parts of cast iron powders
23.5 parts of washing sodas
7 parts of active carbons
12.5 parts of salt
The deoxygenation amount is 163.4ml, is equal to 81.7mlO
2/ g
Application test: get 6 of the fried instant noodles of new production, every 65g packs with bag film respectively, and wherein three bags are contrast, puts into the heavy parcel deoxidation antistaling agent of 2g in three bags in addition.Detect after 8 months and find, the peroxide value that control group is three bags be respectively 0.4027%, 0.4135% and 0.4122% (all above the GB regulation≤0.25% standard), and tangible rancidity appears, and three bags peroxide value using deoxidation antistaling agent has only 0.0879%, 0.0 811% and 0.0864%, no rancidity, fresh-keeping effect is remarkable.
