Powdery tea moisture-proof deoxidizing and refreshing agent

Abstract

The invention discloses a powdery tea moisture-proof deoxidizing and refreshing agent. The technical scheme of the invention is as follows: the powdery tea moisture-proof deoxidizing and refreshing agent consists of acidified red bentonite, acidified dolomite palygorskite clay, acidified bauxite and reduced iron powder. A production method of the powdery tea moisture-proof deoxidizing and refreshing agent comprises the following steps: mixing and acidifying red bentonite, dolomite palygorskite clay and bauxite; tabletting and carrying out heat treatment; and crushing the processed mixture and the reduced iron powder together and packaging to obtain the powdery tea moisture-proof deoxidizing and refreshing agent. The powdery tea moisture-proof deoxidizing and refreshing agent is put in a tea packing container, moisture-proof deoxidizing and refreshing are carried out synchronously, tea is deoxidized and refreshed in a dry state, so that the free oxygen and free water in a tea package can be eliminated, the tea is maintained to be fully dried and can be prevented from mustiness and deterioration due to oxidation, the original flavor and quality of the tea can be ensured, and the shelf life of the tea is prolonged. The powdery tea moisture-proof deoxidizing and refreshing agent is suitable for being put in minitype tea packing containers for containing the tea.

Description

technical field [0001] The invention relates to a deoxidizing preservative, in particular to a powdered tea moisture-proof deoxidizing preservative. Background technique [0002] Tea is easy to absorb moisture and odor, speed up oxidation, and destroy the nutrients and original flavor of tea. It is necessary to pay attention to anti-oxidation, moisture and odor pollution during storage to ensure the quality of tea. [0003] Tea is most suitable for sealed storage under the condition that its own water content is less than 5%. The national standard stipulates that the water content of tea is ≤7.5%. When the water content is 10%, mildew smell is easy to appear; when the water content exceeds 12%, mold is easy to grow in large numbers, the mildew smell will be strengthened, and even moldy and agglomerated, making it impossible to continue drinking. [0004] At present, the moisture-proof and deoxygenated fresh-keeping methods of tea mainly include: lime dehumidification and f...

Problems solved by technology

[0006] Sodium chloride, ferrous sulfate and urea in the above-mentioned patents are all materials with strong hygroscopic ability, and are relatively easy to deliquesce in the air. The water content of the finished products of activated carbon and activated soil is allowed to be ≤10.0%, and these materials are crushed and mixed. During the process, it will absorb a large amount of water in the air, and quickly wrap zinc, iron, activated carbon, activated soil and water-absorbing resin, reducing the effect of deoxidizer. Water-absorbing resin can only play the role of rapid water absorption in aqueous solution, and It cannot effectively adsorb sodium chloride, ferrous sulfate, urea, and moisture in various dry and fresh items. Therefore, the shortcoming of the above-mentioned patent is "a deoxidizer of a two-component system" produced by this technology Directly affect the actual use effect of the deoxidizer
