Embodiment 1

[0026] A food desiccant comprising the following components by weight:

[0027] 30 parts of acrylonitrile grafted starch, 4 parts of calcium chloride, 2 parts of iron powder, 1 part of powdered activated carbon, 0.1 part of sodium dehydroacetate and 0.1 part of hydroxypropyl cellulose.

[0028] Among them, the particle diameters of iron powder and powdered activated carbon are both 40 mesh.

[0029] The preparation method of above-mentioned food desiccant, comprises the following steps:

[0030] (1) the acrylonitrile grafted starch is pulverized to a particle diameter of 40 orders, and then mixed with calcium chloride and iron powder;

[0031] (2) Continue to add powdered activated carbon, sodium dehydroacetate and hydroxypropyl cellulose, mix, then add water and stir, granulate and shape, dry at 0.1MPa and 100°C, cool to room temperature, and finally seal the bag. A safe and environment-friendly food desiccant is prepared.

Embodiment 2

[0033] A food desiccant comprising the following components by weight:

[0034] 20 parts of sodium polyacrylate, 6 parts of calcium chloride, 3 parts of iron powder, 1 part of powdered activated carbon, 0.2 part of sodium dehydroacetate and 0.1 part of ethyl cellulose.

[0035] The preparation method of above-mentioned food desiccant, comprises the following steps:

[0036] Among them, the particle diameters of iron powder and powdered activated carbon are both 40 mesh.

[0037] (1) Sodium polyacrylate is crushed to a particle size of 40 mesh, then mixed with calcium chloride and iron powder;

[0038] (2) Continue to add powdered activated carbon, sodium dehydroacetate and ethyl cellulose, mix, then add water and stir, granulate and shape, dry at -0.1MPa, 90°C, cool to room temperature, and finally seal the bag. A safe and environment-friendly food desiccant is prepared.

Embodiment 3

[0040] A food desiccant comprising the following components by weight:

[0041] 25 parts of sodium polyacrylate, 6 parts of calcium chloride, 3 parts of iron powder, 2 parts of powdered activated carbon, 0.3 part of sodium propionate and 0.1 part of sodium carboxymethyl cellulose.

[0042] The preparation method of above-mentioned food desiccant, comprises the following steps:

[0043] Among them, the particle diameters of iron powder and powdered activated carbon are both 40 mesh.

[0044] (1) Sodium polyacrylate is crushed to a particle size of 40 mesh, then mixed with calcium chloride and iron powder;

[0045] (2) Continue to add powdered activated carbon, sodium dehydroacetate and ethyl cellulose, mix, then add water and stir, granulate and shape, dry at -0.08MPa, 80°C, cool to room temperature, and finally seal the bag. A safe and environment-friendly food desiccant is prepared.

Abstract

The invention discloses a food desiccant and a preparation method thereof. The food desiccant comprises the following components in parts by weight: 20-40 parts of super water-absorbent resin, 1-10 parts of calcium chloride, 1-5 parts of iron powder, 1-5 parts of powdered activated carbon, 0.01-1 part of a mildew inhibitor and 0.01-1 part of an adhesive. The preparation method comprises the following steps: (1) pulverizing the super water-absorbent resin into powder of 40-60 meshes in particle size, and then performing mixing with the calcium chloride and the iron powder; and (2) continuing adding the powdered activated carbon, the mildew inhibitor and the adhesive, performing mixing, adding water, performing stirring, granulating and forming, performing drying in vacuum and performing cooling to room temperature to obtain the food desiccant. The food desiccant prepared by the preparation method can be used for performing desiccation, preservation and mold prevention on food and is nonhazardous to a human body.

Description

technical field [0001] The invention belongs to the technical field of food safety, and in particular relates to a food desiccant and a preparation method thereof. Background technique [0002] Food desiccants are dehydrating agents that absorb water vapor or moisture from food packaging, and are substances that have a hygroscopic function. It absorbs water molecules in its own structure or absorbs water molecules to change its chemical structure into another substance by physical or chemical means. It is used in food packaging, transportation and storage to prevent food from getting wet and to ensure food quality. [0003] At present, the most widely used food desiccants include silica gel desiccant, molecular sieve desiccant, lime desiccant, bentonite desiccant and so on. Silica gel desiccant has fast adsorption speed and strong adsorption capacity, but its production process usually involves the reaction of sodium silicate and sulfuric acid, and undergoes a series of pro...
