Description
Technical field
The invention belongs to food preservative technology field, specifically a kind of nut pack dedicated double deoxidizer and its
Preparation method.
Background technique
With greatly developing for domestic agricultural, China's nut industry has also obtained quick development, and has become heavily fortified point
Fruit consumes fastest-rising country.But since (especially unsaturated fat) content fatty in nut products is high, lead to product
It is easy to happen oxidation deterioration in processing, transport, storage, to reduce the quality of product.
Deoxidier is common fresh-keeping agent in the nut process of circulation, its working principle is that oxygen uptake ingredient is gone back by oxidation
Oxygen inside former method consumption nut packaging bag, to achieve the effect that pack interior anaerobic.For a long time, iron powder is deoxidation
Main reducing agent in agent oxygen uptake principle, is easily oxidized by oxygen in cationic solution as Fe2O3And Fe (HO)3.But such is de-
Oxygen agent is absorbing in packaging bag after oxygen, due to packing internal and external pressure difference, causes nut packaging shrivelled, and be easy to happen damage
It is bad.Therefore, solve problems also become nut circulation, storage in major issue.Na2S2O3It is exposed to wet air
In, it can be reacted rapidly with oxygen and generate SO2, to achieve the purpose that consume oxygen；Then pass through NaHCO3It is generated in absorbing reaction
SO2And generate CO2, packaging bag inside and outside air pressure balance can be maintained.But SO in order to prevent2Portion influences product product within a package
Matter, such deoxygenation need faster deoxidation rate, add suitable NaOH in the double deoxidizer in the present invention to improve
Ion concentration is to accelerate reaction rate and extra CO can be absorbed2；In addition, absorbing the oil on deoxidier surface by montmorillonite
Rouge, to promote oxidation also reaction to go on smoothly.Based on above-mentioned reaction purpose principle, the present invention uses Na2S2O3、NaHCO3、
NaOH, montmorillonite etc. prepare nut specific complex deoxidier.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of nuts to pack dedicated double deoxidizer, by different function
Raw material simultaneously it is hybrid packed, reduce deoxidier preparation process in O2The loss of absorbent is then applied to the packaging of nut
In bag, anaerobic in packaging bag is achieved the purpose that by principle of oxidation and reduction and reduces nut lipid oxidation.In addition, passing through
CO2Releasing agent adjusts the air pressure balance in packaging bag, prevents from packing deformation caused by due to oxygen reduces.
In order to achieve the above object, the technical solution adopted by the present invention is that: it is dedicated compound to provide a kind of nut packaging
Deoxidier and preparation method thereof, including oxygen absorber, carbon dioxide releasing agent and carrier.The O2Absorbent include 15% ~
35% Na2S2O3, the CO2Releasing agent includes 15% ~ 35% NaHCO3, the carrier include 1% ~ 3% active carbon, 5% ~
10% NaOH, 5% ~ 15% water and 5% ~ 60% montmorillonite.
In a preferred embodiment of the present invention, it includes 30% Na that nut, which packs dedicated double deoxidizer,2S2O3, 30%
NaHCO3, 2% active carbon, 8% NaOH, 10% water and 20% montmorillonite.
As shown in Figure 1, the present invention also provides a kind of nuts to pack dedicated double deoxidizer preparation method, feature exists
In to different component use while mixed method, comprising the following steps:
1) carrier mixes: NaOH being added in water, after NaOH all dissolution, active carbon, montmorillonite is added, is uniformly mixed.
2) hybrid packed: by O2Absorbent, CO2Releasing agent and the carrier mixed are hybrid packed simultaneously, and are placed in and are equipped with
In the packaging bag of nut.
The beneficial effects of the present invention are:
