Problems solved by technology

[0003] However, the existing deoxidizers have a single function, the main function is to absorb oxygen, which will not have a great impact on the freshness of general flexible packaging, but it will have a greater impact on bottled or canned packaging. After the oxygen is absorbed, the bottle or can will be sucked under the action of the external atmospheric pressure, which not only affects the appearance of the product, but also easily damages the food in the package, making the food deteriorate, which greatly limits the scope of use of the deoxidizer

Embodiment 1

[0024] This embodiment provides a modified atmosphere deoxidizing preservative, which includes the following components by mass percentage:

[0025]

[0026]

[0027] The components of the dispersant are one or more combinations of diatomite, zeolite and ore soil. The dispersant has a dispersing effect on the modified atmosphere deoxidation preservative and improves the fluidity of ingredients.

[0028] The sodium ascorbate is used to absorb the oxygen in the container, chemically reacts with oxygen, and removes oxygen. It is the main absorber of oxygen. When sodium ascorbate reacts with oxygen, an organic acid is generated. React to generate organic carbonate, water and carbon dioxide, so as to release an equal amount of carbon dioxide while absorbing oxygen. The activated carbon is used as a reaction accelerator to accelerate the oxidation reaction;

[0029] The ascorbic acid directly reacts with the sodium bicarbonate, and the generated water increases the humidity o...

Embodiment 2

[0039] This embodiment provides a modified atmosphere deoxidizing preservative, which includes the following components by mass percentage:

[0040]

[0041] Wherein, the components of the carbon dioxide release regulator are composed of calcium hydroxide and calcium oxide, the components of the dispersant are one or more combinations of diatomite, zeolite, ore, and the calcium hydroxide , Calcium oxide group accounts for the mass percent of modified atmosphere type deoxidizing preservative:

[0042] Calcium hydroxide 0.1% ~ 0.45%;

[0043] Calcium oxide 0.1% to 0.45%.

Embodiment 3

[0045] This embodiment provides a modified atmosphere deoxidizing preservative, which includes the following components by mass percentage:

[0046]

[0047] Wherein, the components of the carbon dioxide release regulator are composed of calcium hydroxide and calcium oxide, the components of the dispersant are one or more combinations of diatomite, zeolite, ore, and the calcium hydroxide , Calcium oxide group accounts for the mass percent of modified atmosphere type deoxidizing preservative:

[0048] Calcium hydroxide 0.1% ~ 0.4%;

[0049] Calcium oxide 0.1% to 0.4%.

[0050] The beneficial effect of the modified atmosphere deoxidation preservative of the present invention is that the deoxidizer can release carbon dioxide while absorbing oxygen, and adjust the amount of carbon dioxide through the carbon dioxide release regulator to maintain the balance of the total volume of oxygen and carbon dioxide in the container bottle, ensuring The air pressure inside and outside th...

Abstract

The invention discloses a gas regulation type deoxidation preservative which comprises fructose, ascorbic acid, sodium ascorbate, sodium bicarbonate, sodium carbonate, activated carbon, a carbon dioxide release regulator, a dispersant and water. The gas regulation type deoxidation preservative can absorb oxygen while releasing carbon dioxide, regulates the amount of carbon dioxide through the carbon dioxide release regulator, maintains the balance of the total volume of oxygen and carbon dioxide in a container bottle, ensures the consistency of pressures inside and outside the container, is high in practicability, meets the production and living needs, is wide in use, and has stronger promotion significance.

Description

technical field [0001] The invention relates to a fresh-keeping agent, in particular to a modified-atmosphere deoxidizing fresh-keeping agent. Background technique [0002] In recent years, with the development of the food industry and the improvement of packaging materials, deoxidizers have received more and more attention in China, and their applications have become more and more extensive. As a new material for food preservation, the deoxidizer is packed in the same container with the food. The deoxidizer absorbs the oxygen in the container, making the container in an oxygen-free state, and the food can be preserved. [0003] However, the existing deoxidizers have a single function, the main function is to absorb oxygen, which will not have a great impact on the freshness of general flexible packaging, but it will have a greater impact on bottled or canned packaging. After the oxygen is absorbed, the bottle or can will be sucked under the action of the external atmospher...
