Problems solved by technology

[0004] All of the above products have insufficient oxygen absorption speed, the air permeability required for the oxygen absorption reaction of the packaging material needs to be perforated or pierced, there is powder leakage, the air permeability is unstable, and the air permeability exceeds 400ml / kpa, which needs to be repeatedly pierced several times, etc. Disadvantages, especially the oxygen absorption rate related to the air permeability of the packaging material cannot meet the freshness needs of meat and fish

Embodiment 1

[0026] Example 1: Iron powder treatment includes iron powder and a water film layer attached to the surface of the iron powder. In this embodiment, the iron powder is reduced iron powder with a particle size of 200-300 mesh, and the water The film layer includes powdered calcium chloride with a quality of 2.1% of the total mass of the iron powder to be treated, powdered activated carbon with a quality of 2.6% of the total mass of the iron powder to be treated, and water with a quality of 1.0% of the total mass of the iron powder to be treated. The thickness of the layer was 0.4 μm.

Embodiment 2

[0027] Embodiment 2: Iron powder treatment includes iron powder and a water film layer attached to the surface of the iron powder. In this embodiment, the iron powder is reduced iron powder with a particle size of 100-300 mesh, and the water The film layer includes powdery sodium chloride and calcium chloride whose quality is 1.3% of the total mass of the iron powder to be treated, powdered activated carbon with a quality of 3.9% of the total mass of the iron powder to be treated, and 0.6% of the total mass of the iron powder to be treated. Water, the thickness of the water film layer is 1.2 μm.

Embodiment 3

[0028] Embodiment 3: Iron powder treatment includes iron powder and a water film layer attached to the surface of the iron powder. In this embodiment, the iron powder is high-carbon iron powder with a particle size of 80-300 mesh, and the Water film layer comprises that quality is to handle the powdered calcium chloride of iron powder gross mass 3% and thiosulfate (big soda), the quality is to handle the powdery activated carbon of 2.2% of iron powder gross mass and the quality is to handle iron powder 1.5% of the total mass of water, the thickness of the water film layer is 0.4mm.

Abstract

The invention discloses low-temperature deoxidant. The deoxidant is characterized by comprising treated iron powder and reactive groups in the mass ratio of (1-5):1, the treated iron powder comprises iron powder and a water film layer attached to the surface of the iron powder, the water film layer comprises salt, activated carbon and water, mass of the salt in the treated iron powder accounts for 0.8-3.9% of total mass of the treated iron powder, mass of the activated carbon accounts for 2-3.9% of the total mass of the treated iron powder, and mass of the water accounts for 0.5-3% of the total mass of the treated iron powder. The deoxidant is particularly high in oxygenation reaction speed and especially high in capability of absorbing and removing residual minute oxygen, and can lower oxygen in a packing bag to 0.004%O2 within 90minutes at low temperature of 0-4 DEG C.

Description

technical field [0001] The invention relates to a low-temperature oxygen scavenger and its medicine bag packaging material and a preparation method of the medicine bag packaging material, belonging to the technical field of food preservation and product storage and packaging, and can be used as a replacement product for the current oxygen scavenger, including meat Preservation of fish. Background technique [0002] 1980.10 During the period when the applicant was the leader of the rocket engine room of the 8511 Institute, in order to implement the policy of turning the military into civilians and finding rice for cooking, the applicant proposed the subject of "Study on Deoxygenation and Sealing of Rocket Engines to Extend Storage Life". For this reason, he personally organized and led the first oxygen scavenger in my country "801" was developed. This product is formulated by using the mechanism that the corrosion reaction of iron under acidic conditions will consume oxygen. T...
