Embodiment 1

[0027] The preservative raw materials are composed of iron powder, salt, water, activated carbon, pH regulator, water absorbing agent and dispersant, wherein iron powder, salt, water and activated carbon are the main components of oxygen absorption, and the water absorbing agent is used for To absorb moisture, the PH value regulator is used to adjust the pH value of the preservative to ensure the smooth progress of the oxidation reaction of iron powder, and the rate of oxygen and moisture absorption can be controlled by adjusting the ratio of each component. The composition of the salt can be one or more of alkali metal halide salts such as NaCl, KCl, NaBr, and KBr; the pH regulator is calcium hydroxide, calcium oxide, sodium bicarbonate, sodium carbonate, etc. One or more components; the water-absorbing agent can be sodium bromide, sodium iodide, calcium chloride, calcium bromide, magnesium chloride, magnesium bromide, ferric chloride, ferrous chloride, zinc chloride, iodine ...

Embodiment 2

[0030] In the present embodiment, pH regulator is not included, and wherein the mass percentages of various substances of fresh-keeping agent raw materials are as follows:

[0031]

[0032] The product performance of this embodiment is as shown in the table:

[0033]

Embodiment 3

[0035] The mass percentages of various substances of the preservative raw materials are as follows:

[0036]

[0037] Wherein, the water-absorbing agent is a mixture of magnesium chloride and calcium bromide, and the mass ratio of magnesium chloride and calcium bromide is 1:3. The product performance of this embodiment is shown in the table:

[0038]

[0039] The inner layer 10 is a single-layer film, and the material of the inner layer 10 is PE (Polyethylene, polyethylene) air-permeable, moisture-permeable, and heat-sealable film, and the inner layer 10 is not perforated, that is, the inner layer 10 is set without holes.

[0040] The outer layer 20 is a composite film, and the outer layer 20 is distributed with a number of air holes 30, the diameter of the air holes is 1um to 100um. In this embodiment, the outer layer 20 can be a double-layer film, a three-layer film or Four-layer film, when the outer layer 20 is a double-layer film, the outer layer 20 can be a composi...

Abstract

A food antistaling agent with a double absorbing function includes a packaging bag and antistaling agent raw materials placed in the packaging bag, and the antistaling agent consists of iron powder, salt, water, activated carbon, a pH adjusting agent, a water-absorbing agent, and dispersants; a food antistaling agent with a double absorbing function includes a packaging bag and antistaling agent raw materials placed in the packaging bag, and the antistaling agent consists of iron powder, NaCl, water, activated carbon, sodium bromide. and diatomaceous earth; and a food antistaling agent with a double absorbing function includes a packaging bag and antistaling agent raw materials placed in the packaging bag, and the antistaling agent consists of iron powder, sodium bromide, calcium hydroxide, water, activated carbon, a water-absorbing agent, and silicon dioxide. The food antistaling agent with a double absorbing function can remove oxygen and protect against moisture at the same time and ensure that food is placed in a dry and oxygen-free environment, has significant antistaling effect, high practicality and good antistaling effect.

Description

technical field [0001] The invention relates to a food fresh-keeping agent, in particular to a food fresh-keeping agent with double suction functions. Background technique [0002] At present, various food preservatives are widely used in the field of food preservation. Compared with various antioxidants and anti-mold preservatives that are directly added to food, deoxidizers are more effective in food preservation because they do not directly contact with food. It is safe and easy to operate, and has been widely used in the preservation of various foods. The fresh-keeping principle of the deoxidizer is deoxidation and fresh-keeping. It has a good fresh-keeping effect on foods that are susceptible to oxygen deterioration, but it is not only easy to oxidize and deteriorate, but also sensitive to humidity (such as rice, tea, ham sausage, betel nut, etc.) ), simple deoxygenation preservation cannot completely solve the problem. Therefore, many fresh-keeping methods for this k...
