Problems solved by technology

[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
Existing green tea antistaling agents have the following problems: the one is that the antistaling agent is prepared as the main raw material by using montmorillonite active desiccant, which absorbs moisture and easily expands, which cannot effectively keep the tea leaves fresh; Very effective, it is easy to shorten the fresh-keeping time of tea leaves or to deteriorate the quality of tea leaves; the third is that the preservatives in the prior art can only be discarded after one-time use, and cannot be reused

Abstract

The invention provides a green tea antistaling agent and a preparation method thereof. The green tea antistaling agent is prepared from the following raw materials: 30 to 70 parts of moisture resisting agent, 20 to 26 parts of sodium pyrosulfite, 22 to 30 parts of sodium ascorbate, 6 to 10 parts of activated carbon and 12 to 18 parts of iron powder. The green tea antistaling agent provided by the invention has the advantages of high adsorbing and drying speed, high adsorption capacity, no toxicity, no odor, no contact corrosion property and no environmental pollution; in addition, the green tea antistaling agent can be used for removing oxygen, resisting corrosion and removing odor, and is not harmful to a human body and is low in preparation cost; besides, original quality and quality of tea can be ensured, the shelf life of the tea is prolonged and additional value of the tea is improved.

Description

technical field [0001] The invention relates to the technical field of tea, in particular to a green tea preservative and a preparation method thereof. Background technique [0002] At present, the production of Chinese tea, especially famous green tea, is mainly concentrated in spring, and it takes a long time for tea from processing, storage, sales to consumption. As a result, a series of changes in the ingredients in the tea leaves will result in a decline in quality. Nowadays, with the improvement of people's living standards, the requirements for the quality of tea are getting higher and higher, and the quality of tea preservation effect further affects the sales price of tea and the benefits of enterprises. [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 ...
