Problems solved by technology

However, the existing food deoxidizers have a low reaction rate during use, and the deoxidation reaction speed is relatively slow; moreover, most of the existing food deoxidizers have poor water holding performance, and the deoxidizers cannot be used during use. The moisture carried is easy to cause the food to regain moisture, which affects the storage effect of the food

preparation example Construction

[0025] The present invention also provides a preparation method of the deoxidizer, the preparation steps comprising: 1) dissolving the electrolyte with water, adding calcium chloride and stirring evenly; 2) adding a superabsorbent resin to the mixed solution in step 1), After stirring evenly, let it stand for 10-20 minutes to balance the moisture transfer, add filler and silicon dioxide, mix and stir evenly, then add reducing iron powder, and mix for 10-30 minutes, and the mixed material passes through a 30-80 mesh sieve , sealed for subsequent use; 3) after the material in step 2) is cooled, pack it into bags and vacuumize to obtain the deoxidizer of the present invention.

[0026] Preferably, in the bagging and packaging step in step 3), it is preferable to use a packaging film with one-way moisture selective permeation for packaging, so as to effectively prevent the moisture in the deoxidizer content from diffusing into the food.

Embodiment 1

[0028] A deoxidizer for food, which is made of the following components by weight percentage: reduced iron powder: 40%, sodium chloride 2%, calcium chloride: 5%, silicon dioxide: 21%, polyacrylic acid Department of super absorbent resin: 5%, bentonite: 21% and water 6%. The preparation step of described deoxidizer comprises:

[0029] 1) After dissolving sodium chloride with water, add calcium chloride and stir to mix evenly;

[0030] 2) Add polyacrylic acid superabsorbent resin to the mixed liquid in step 1), stir evenly and let it stand for 10 minutes. After the water transfer is balanced, add bentonite and silicon dioxide, mix and stir evenly, add reducing iron powder, Sealed and mixed for 20 minutes, then, the mixed material passed through a 60-mesh sieve, and sealed for later use;

[0031] 3) After the material in step 2) is cooled, it is transferred to an automatic packaging machine for bagging and packaging, and the deoxidizer is obtained after vacuuming.

Embodiment 2

[0033] A deoxidizer for food, which is made of the following components by weight percentage: reduced iron powder: 50%, sodium bromide: 1%, sodium iodide: 5%, calcium chloride: 5%, di Silica: 15%, polyacrylamide superabsorbent resin: 1%, bentonite: 5%, diatomaceous earth: 10%, water: 8%. The preparation step of described deoxidizer comprises:

[0034] 1) After dissolving sodium bromide and sodium iodide with water, add calcium chloride and stir to mix evenly;

[0035] 2) Add polyacrylamide-based superabsorbent resin to the mixture in step 1), stir evenly and let it stand for 30 minutes. After the water transfer is balanced, add bentonite, diatomaceous earth and silicon dioxide, mix well and then add Reduced iron powder, sealed and mixed for 15 minutes, then, the mixed material passed through a 60-mesh sieve, and sealed for later use;

[0036] 3) After the material in step 2) is cooled, it is transferred to an automatic packaging machine for bagging and packaging, and the deo...

Abstract

The invention discloses a deoxidizing agent for foods. The deoxidizing agent comprises, by weight, 40-60% of iron powder, 1-6% of electrolytes, 5-15% o calcium chloride, 13-25% of silicon dioxide, 1-5% of macromolecule water absorbing resin, 10-23% of fillers and 5-10% of water. The invention further discloses a method for preparing the deoxidizing agent. The method includes preparation steps of 1), dissolving the electrolytes by the aid of the water, adding the calcium chloride into the electrolytes and uniformly stirring the electrolytes, the calcium chloride and the water to obtain mixed liquid; 2), adding the macromolecule water absorbing resin into the mixed liquid obtained at the step 1), uniformly stirring the macromolecule water absorbing resin and the mixed liquid to obtain first mixtures, then allowing the first mixtures to stand still for 10-20 minutes, adding the fillers and the silicon dioxide into the first mixtures, uniformly mixing and stirring the fillers, the silicon dioxide and the first mixtures to obtain second mixtures, adding the reductive iron powder into the second mixtures, mixing the second mixtures and the reductive iron powder with one another under closed conditions for 10-30 minutes, sieving mixed materials by the aid of sieves with 30-80 meshes and sealing the mixed materials for standby application; 3), cooling materials obtained at the step 2), then quantitatively bagging and packaging and vacuumizing the materials to obtain the deoxidizing agent. The deoxidizing agent for the foods and the method have the advantages that the method includes simple preparation processes, excellent deoxidizing and drying effects can be realized, and moisture regaining of existing foods due to the fact that moisture carried by contents in existing deoxidizing agents is permeated into the existing foods can be effectively prevented.

Description

technical field [0001] The invention relates to a deoxidizer for food and a preparation method thereof, belonging to the technical field of food preservation. Background technique [0002] As a kind of preservative, deoxidizer can absorb oxygen during food storage, slow down the oxidation rate of food, effectively inhibit the growth of mold and aerobic bacteria, and prolong the shelf life of food. However, the existing food deoxidizers have a low reaction rate during use, and the deoxidation reaction speed is relatively slow; moreover, most of the existing food deoxidizers have poor water holding performance, and the deoxidizers cannot be used during use. The carried moisture can easily lead to moisture resurgence in food, which affects the storage effect of food. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a deoxidizer for food with high deoxidation efficiency and not easy to return w...
