Abstract

The invention relates to the technical field of storage of Dexon acid dried tea, in particular to a storage and preparation method of Dexon acid dried tea in a high-temperature and humid environment. The storage method comprises the following steps: directly loading the Don acid dried tea into a porcelain jar, sealing the mouth of the porcelain jar, and storing, or loading the Don acid dried tea into a plastic bag, sealing the mouth of the plastic bag, loading the plastic bag into a box, sealing the mouth of the box, storing, and putting under a sun-curing shed at a place with the altitude of about 900m under the requirements of temperature and humidity of 26-34 DEG C and humidity of 61-78%, the temperature is 26-34 DEG C, the humidity is 61-78%, and the time is 4-6 hours at the temperature of 30-34 DEG C per day, or the tea leaves are placed in a display hall at the altitude of about 900 meters, the temperature and humidity requirements are as follows: the temperature is 26-34 DEG C, the humidity is 61-78%, and the time is 4-6 hours at the temperature of 30-34 DEG C per day. In the storage process of the Don acid tea, the temperature is increased, the proper humidity is kept, and conditions for enabling lactobacillus to play a greater role are created, so that contents of the Don acid tea are converted in an accelerated manner and are changed to be mellow, sweet and moist after taste, and the requirements of consumers on the taste quality of the Don acid tea are met in advance.

Description

Technical Field

[0001] The invention relates to the technical field of preparation of Deang acid tea dry tea, and in particular to a storage preparation method of Deang acid tea dry tea in a high-temperature and suitable-humidity environment. Background Art

[0002] When storing De'ang sour tea dry tea, the doors and windows of the storage warehouse should be closed, and the temperature inside the warehouse should be controlled below 25℃. When the temperature of the warehouse is higher than 25℃, cooling measures should be taken. When the temperature inside the tea pile is higher than the temperature inside the warehouse, the piles can be turned over to dissipate the temperature inside the piles and lower the temperature inside the piles to the temperature inside the warehouse. The relative humidity should be controlled below 70%. When the relative humidity is higher than 70%, dehumidification measures should be taken.

[0003] When the existing Deang sour tea dry tea is stored, it is impossible to maintain appropriate temperature and humidity, thus creating conditions for Lactobacillus to play a greater role, reducing the conversion efficiency of the contents of Deang sour tea, and changing it to a mellow, sweet and smooth taste; the taste quality of Deang sour tea cannot quickly meet the requirements of consumers, and the economic and social benefits are low.

[0004] Therefore, in view of the above-mentioned limitation of the low-temperature storage environment, a storage and preparation method of Deang acid tea dry tea in a high-temperature and suitable humidity environment can be designed. Summary of the invention

[0005] In order to overcome the limitations of low temperature storage environment.

[0006] The technical solution of the present invention is: a storage and preparation method for Deang sour tea dry tea under a high temperature and suitable humidity environment, and the storage method is as follows: Deang sour tea dry tea is directly put into a porcelain jar and the mouth of the porcelain jar is sealed for storage, and is placed under a drying shed at an altitude of about 900 meters. The temperature and humidity requirements are: temperature 26°C-34°C and humidity 61-78%, and the time at 30°C-34°C is 4-6 hours per day.

[0007] A method for storing and preparing Deang sour tea dry tea in a high-temperature and suitable humidity environment. The storage method is as follows: the Deang sour tea dry tea is packed in a plastic bag and the bag mouth is sealed, then packed into a box and the box mouth is sealed for storage, and placed under a drying shed at an altitude of about 900 meters. The temperature and humidity requirements are: temperature 26°C-34°C and humidity 61-78%, and the time at 30°C-34°C is 4-6 hours per day.

[0008] A method for storing and preparing Deang sour tea dry tea in a high-temperature and suitable humidity environment. The storage method is as follows: the Deang sour tea dry tea is directly put into a porcelain jar and the mouth of the porcelain jar is sealed for storage, and the jar is placed in an exhibition hall at an altitude of about 900 meters. The temperature and humidity requirements are: temperature 26°C-34°C and humidity 61-78%, and the time at 30°C-34°C is 4-6 hours per day.

[0009] A method for storing and preparing Deang sour tea dry tea in a high-temperature and suitable humidity environment. The storage method is as follows: the Deang sour tea dry tea is packed in a plastic bag and the bag mouth is sealed, then packed into a box and the box mouth is sealed for storage, and placed in an exhibition hall at an altitude of about 900 meters. The temperature and humidity requirements are: temperature 26°C-34°C and humidity 61-78%, and the time at 30°C-34°C is 4-6 hours per day.

[0010] Beneficial effects of the present invention:

[0011] The use of Deang sour tea dry tea storage equipment and preparation method under high temperature and suitable humidity environment breaks the traditional storage and processing method of tea. It uses the principle that the optimal growth temperature of lactic acid bacteria and its key microorganism Lactobacillus formed in Deang sour tea products during anaerobic fermentation processing is 30-34°C. During the storage process of Deang sour tea, the temperature is increased and the humidity is maintained at appropriate levels to create conditions for Lactobacillus to play a greater role, thereby accelerating the transformation of Deang sour tea contents and changing them towards a mellow, sweet and moist taste, so that the product can meet consumers' requirements for the taste quality of Deang sour tea in advance, with obvious economic and social benefits.
