Background technology
While food production and food processing is developed, food fresh keeping is highly valued people.Prevent to reach food
It is rotten, fresh-keeping, extend the purpose of effective period of food quality and shelf life, people employ various preservation techniques, such as cold preservation, irradiation, but
Facilitate the most and economic technology is using methods such as deoxidizer preservations.It is closed by removing in chemical reaction, short time
Oxygen in container, makes growth of the food in microorganisms such as anaerobic state, effective control antibacterial, mycetes, prevents Oxidation of Fat and Oils, from
And the color of food can be effectively kept, and prevent the nutrient substance such as vitamin to be oxidized destruction, extend effective period of food quality, one
As be to be made up of host, filler, activating agent, modifying agent or Function Extension agent.
Deoxidizer can be divided into organic substrate deoxidizer and inorganic matrix deoxidizer.Organic substrate deoxidizer has enzyme, anti-bad
Hematic acid etc..Ascorbic acid is in itself reducing agent, in the case of aerobic, makees that catalyst can be oxidized or dehydrogenation is anti-bad with copper ion
Hematic acid, so as to remove environment in oxygen, commonly use this method to remove food liquid in oxygen, it be at present use deoxidizer in safety
Property higher one kind, enzyme system deoxidizer it is conventional be the glycoxidative alcohol of Fructus Vitis viniferae, consume oxygen when being and being oxidized to gluconic acid using glucose
To reach deoxidation purpose.Inorganic matrix deoxidizer has reduced iron powder, its principle be iron powder in the presence of oxygen and vapor,
It is oxidized to hydrated ferric oxide..At present conventional deoxidizer be easy to get with raw material, low cost, the application of safe iron series deoxidizers
It is most wide, iron series deoxidizers typically with iron powder as base stock, be widely used in wet bread flour, wet face, wet-milling silk, the wet point heart, half
The numerous foods such as dry fish product.But at present iron series deoxidizers also has that low-temperature deoxidation effect is poor, and high using rear regain, oxygen uptake is fast
Rate is low, causes the problems such as its is fresh-keeping, antiseptic effect is poor.
The content of the invention
The technical problem to be solved:It is poor for current iron series deoxidizers low-temperature deoxidation effect, using rear moisture regain
Rate is high, and speed of oxygen intake is low, causes the drawbacks of its is fresh-keeping, antiseptic effect is poor, there is provided one kind using montmorillonite as filler,
Platinum ion is provided by platinum acid chloride solution, montmorillonite-loaded platinum ion, and melting parcel platinum ion at high temperature is made, increases catalysis
Efficiency, is burnt in nitrogen by magnesium powder and generates magnesium nitride, and is melted in filler surface, uses hydrogen peroxide oxidation humic acid,
Sulfonation is carried out to aoxidizing humic acid by sulfur trioxide, increases the absorption to sulfur dioxide and ammonia, finally with iron powder, Lian Erya
The method that sodium sulfate is mixed with complex food deoxidizer, the present invention generates hydrogen-oxygen using magnesium nitride and water under the catalysis of platinum
Change magnesium and ammonia, ammonia, the titanium dioxide that ammonia and sodium dithionite are produced with oxygen reaction are adsorbed by the humic acid for processing
Sulfur, produces ammonium hydrogen sulfate in the environment of having water, and quickly with oxygen reaction generates ammonium sulfate, to protecting during iron powder deoxidation,
The principle of deoxidation effectiveness being improved simultaneously, efficiently solving that traditional iron series deoxidizers low-temperature deoxidation effect is poor, regain is high, and oxygen uptake is fast
Rate is low, the problem for causing its fresh-keeping, antiseptic effect poor.Preparation process of the present invention is simple, and gained complex food deoxidizer has
Preferably low-temperature deoxidation effect, can effectively reduce regain after use, improve speed of oxygen intake, with preferably fresh-keeping, anti-corrosion effect
Really.

1~2h is burnt, then room temperature is cooled to the furnace, calcined material is removed and placed in crush in pulverizer, cross 200 mesh sieves, collection is sieved
Grain;
(2)The above-mentioned granule that sieves is mixed homogeneously with the magnesium powder of its quality 10~15%, and is put in electric smelter, protected using nitrogen
Shield, design temperature is 810~850 DEG C, insulation 40~50min of melting, after naturally cooling to room temperature, molten mixture is taken out,
In being put into vacuum ball grinder, by ratio of grinding media to material 20:1, a diameter of 50mm steel balls are added, with 150r/min 40~50min of ball milling, collect
Ball milling thing, it is standby;
(3)By mass percentage, it is 10% hydrogen peroxide, 3~5% sulfur trioxide to take 45~50% mass fractions, and remaining is 300 mesh
Humic acidss, are first put into 300 mesh humic acid and mass fraction in flask for 10% hydrogen peroxide, with 150r/min stirring 50~
After 70min, sulfur trioxide is added, 4~5h of stirring reaction is subsequently filtered, in being in cleaning mixture using distilled water wash filtering residue
Property, then filtering residue is put in air-dry machine air-dried, the air-dried thing of collection;
(4)Count by weight, weigh 40~50 parts of steps(2)Standby ball milling thing, 30~35 parts of above-mentioned air-dried things, 28~33
Part iron powder, 12~13 parts of Sodium Chloride and 8~10 parts of sodium dithionites, in being sequentially placed into mill, with 200r/min 30 are milled
~40min, collects thing of milling, and is put into sealing preserve in hermetic bag, you can obtain complex food deoxidizer.
The application process of the present invention:To be put in food pack after complex food deoxidant packing obtained in the present invention,
The control deoxidizer amount of being put into accounts for the 1.2~1.3% of food quality, then food pack is placed under the conditions of -8~40 DEG C, 3~4
After it, after testing oxygen inhalation rate is 71.6~82.3%, can in effective control food the microorganism such as antibacterial, mycete growth, prevent
Oxidation of Fat and Oils, and food color can be effectively kept, prevent nutrient substance to be oxidized destruction, storage food moisture regain in 2~3 months
Rate is 5.3~7.8%, is worthy to be popularized and uses.
Compared with additive method, Advantageous Effects are the present invention:
(1)Preparation process of the present invention is simple, and gained complex food deoxidizer low-temperature deoxidation effect is good, and oxygen inhalation rate is than traditional deoxidizer
Improve 26~35%;
(2)Complex food deoxidizer of the present invention reduces 25~30% using rear regain than traditional deoxidizer, with preferable
Fresh-keeping, antiseptic effect, can be applicable to cake food, leisure food, solid carbon dioxide product, dry meat products field.
