Abstract
The present invention relates to a kind of fresh-keeping deoxidizer, form by soybean cake and other auxiliary material after cast iron powder and the pulverizing.Both can pack use separately, also can be used by the vacuum piston pump of driven by motor or the storage that has a hand piston pump, also can be used with refrigerator cold-storage is indoor, its deoxidation effect can reach 95%.Raw material of the present invention is common raw material, and processing is simple, and is easy to use, is not only applicable to the warehouse room, also is applicable to various less occasions, needs the use of the different purposes of fresh-keeping or deoxygenation.
Description
The invention belongs to a kind of oxygen scavenger, be particularly related to be used for food and/or dress material and valuables fresh-keeping with the storage chemical composition.
Fresh-keeping and the storage of food, dress material and valuables has the whole bag of tricks such as machinery, physics and chemistry.For example Chinese patent application numbers 91208856.7,87208038 and 87209035 all discloses the vacuum storage container, but qualification because of its air component and vacuum pump principle of work, vacuum effectiveness generally can only reach about 70% in the storage as people are known.On the other hand, fresh-keeping and the oxygen scavenger made from chemical composition, for example respectively disclosed with sodium-chlor, citric acid, vitamins C and water and with potassium permanganate, unslaked lime, vermiculite and water and the preservation agent prepared with potassium permanganate, unslaked lime, vermiculite and water in application number 86102550,87100004, the only suitable bulk storage plant that above-mentioned product has, the technical sophistication that has is so be not suitable for daily use.A kind of antistaling tablet is disclosed in Chinese patent application numbers 89104663.1, the main composition of forming by pyrosulfite, stearate, silica particles and tackiness agent, the said composition chemical ingredients is too much, selling at exorbitant prices, also incompatibility daily be simple and easy to the raw material requirement of producing.
The objective of the invention is provides the fresh-keeping deoxidizer that a kind of raw material is simple, effect is obvious and easy to process for the fresh-keeping of food and/or dress material and valuables and storage.
Further purpose of the present invention is to provide a kind of fresh-keeping deoxidizer that can improve original various vacuum freshness retaining storage deoxidation effects.
The objective of the invention is to realize by the composition of following component.
A kind of fresh-keeping deoxidizer is made up of soybean cake and other auxiliary material after cast iron powder and the pulverizing, wherein:
(1) cast iron powder content is 50-75%(weight) (50-200 order)
(2) the soybean cake content after the pulverizing is 20-50%(weight) (50-100 order)
(3) talcum powder content is 0-30%(weight)
(4) salt content is a 0-5%(weight)
Wherein, the optimum content of cast iron powder is a 50%(weight), the soyflour optimum content after the pulverizing is a 50%(weight).
Can be placed directly in the container after as the fresh-keeping deoxidizer of above-mentioned compound composition and to use, also can insert by the vacuum piston pump of driven by motor or have in the fresh-retaining preserving device of hand piston pump with poromeric material (container of weaving into less than the plant bar of component particle size as plastics bag, paper and gap) parcel.
In the cast iron powder, the positive ion Fe of iron
2+Content accounts for 95% of cast iron powder total amount, and C is 3.5% in addition, other element is 1.5%, because Fe
2+Ion very easily generates Fe with airborne oxygen generation redox reaction
2O
3, its reaction formula is as (I):
4Fe
2++6O
2→2Fe
2O
3（Ⅰ）
In addition, also rich in vitamin E acetic ester (Vitamin E Actate) in the soybean cake of used broken stone in this composition, its structural formula are as (2):
Because there are a plurality of unsaturated double-bonds in this structure, thus be easy to oxidation by airborne oxygen institute, thus have stronger reductibility, so soybean cake can use as oxidation inhibitor.
The cast iron powder is crushed to the 50-200 order, mixed with defatted soyflour (being broken to about 50-100 order with soybean cake powder forms), add other a small amount of auxiliary material, for example, after fully mixed, can make fresh-keeping deoxidizer of the presently claimed invention as the talcum powder of stopping composition with as the salt of sanitas.The fresh-keeping deoxidizer of gained can be used as deoxidizing antistaling agent after with the poromeric material parcel, perhaps insert by the vacuum piston pump of driven by motor or have in the storage of hand piston pump, be mated use, improve deoxidation effect.Also can place fresh-keeping reductor of the present invention refrigerator cold-storage indoor, improve preservation liquid storage time and fresh-keeping quality.
Raw material of the present invention is a utmost point common raw material, draws materials conveniently, and processing is simple, and it is also convenient to use, and is not only applicable to the warehouse room, also is applicable to the use of various less occasions, different purposes; Be used with various vacuum storage containers, can reach the deoxidation effect more than 95%, can only reach 70% deoxidation effect than simple vacuum fresh-keeping box high by 25%.
Fig. 1 is the synoptic diagram by the fresh-retaining preserving device of driven by motor vacuum piston pump of putting into fresh-keeping deoxidizer.
Fig. 2 is a synoptic diagram of putting into the fresh-retaining preserving device that has hand piston pump of fresh-keeping deoxidizer.
Wherein symbol is represented respectively among the figure

Provide specific embodiments of the invention below in conjunction with accompanying drawing.
Embodiment 1
A kind of deoxidation antistaling agent is made up of the soybean cake after cast iron powder and the pulverizing, wherein
Cast iron powder 50%(weight)
Soybean cake 50%(weight after the crushing)
Cast iron powder is crushed to 50 orders, mixes, behind the paper parcel with ventilation property, put into common vessel, can use as deoxidizing antistaling agent with defatted soyflour (about 50 orders).
The deoxidizing antistaling agent that vacuum reservoir (referring to Fig. 1) a kind of and by the vacuum pump of driven by motor is used, its component is:
Cast iron powder (100 order) 75%(weight)
Soyflour (100 order) 25%(weight)
If the deoxidation antistaling storing device volume as Fig. 1 is 150 liters, referring to (formula-1), can get 1 gram cast iron powder can be 0.41 gram except that oxygen; If the interior vacuum tightness of container this moment is 0.7 normal atmosphere, then the gaseous tension in the container is 0.3 normal atmosphere, then according to gas equation:
PV＝ (W)/(M) RT＝nRT （3）
In the formula: M-molecular weight gas (gram)
W-gas weight (gram)
The n-number of moles of gas
So n=(PV)/(RT)=1.875(mol)
Oxygen content in air about 20%.
Then the oxygen mole number be 0.375mol, be converted to weight be 12 the gram.But by above-mentioned cast iron powder deoxygenation destiny magnitude relation as can be known, to consume the cast iron powder be 29 to restrain to 12 gram oxygen.If can get, need about 10 grams of soyflour according to this prescription soyflour and cast iron powder relation.
10 gram soyflours with to be crushed to 100 purposes 30 gram cast iron powder fully mixed, are inserted behind the plastic bag packaging made from the PVC film on the position of reductor storeroom 6 of the casing 2 that stock is housed.Regulate control valve then, drive vacuum piston pump 3 with motor 4 and vacuumize, when vacuum tightness was 70% in being evacuated to case, pump quit work, seal case, and fresh-keeping deoxidizer can work long hours.
A kind of deoxidizing antistaling agent that is used with the vacuum reservoir (referring to Fig. 2) that has hand vacuum pump, its component is:
Cast iron powder 50%(200 order) (weight)
Defatted soy flour (100 order) 20%(weight)
Talcum powder 27%(weight)
If the deoxidation antistaling storing device volume as Fig. 2 is 20 liters, as the method for calculation among the embodiment 2, then by above-mentioned prescription cast iron powder 4 grams, defatted soy flour 1 gram, talcum powder 2 grams, salt 0.25 gram.
With 1 gram soyflour with to be crushed to 200 purposes 4 gram cast iron powder fully mixed, on the reductor storeroom of inserting behind the paper bag packing in the casing 2 that stock can be housed 6.Shake hand vacuum pump then, be evacuated to 70% vacuum tightness after, seal case.Fresh-keeping deoxidizer gets final product long term operation.
