Problems solved by technology

However, tea is a product that is produced seasonally and consumed throughout the year, especially citrus tea is mainly produced in the rainy and high-humidity spring, if it is not kept fresh, citrus tea will soon lose its proper quality and flavor and health effects
At present, most of the fresh-keeping methods applied to citrus tea are single-factor fresh-keeping measures such as dehumidification, oxygen removal, and antibacterial, and the effect is not ideal. In particular, the specific technical parameters of each fresh-keeping technology are difficult to control and lack practical operability.

Embodiment 1

[0021] (1) Utilize 60Co-γ rays to carry out radiation sterilization treatment on tea leaves, and the treatment time is 3h;

[0022] (2) The de-enzyming machine is de-enzymed, the de-enzyming temperature is 90°C, and the de-enzyming method is fast and fast at high temperature, less transparent and more stuffy, so that after de-enzyming and dehydration, the water content of the dehydrated tea leaves is 50%;

[0023] (3) For second greening, the dehydrated tea leaves are put into a microwave greening machine for second greening, the temperature of microwave greening is 85° C., the time is 20 min, and the frequency is 2000 MHz; the water content of the tea leaves after the second greening is 15%.

[0024] (4) Put the dehydrated tea leaves that have been finished for the second time into a vacuum box at a temperature of -30 to -20°C, and at the same time inject a mixed gas for 24 hours, wherein the volume ratio of argon, carbon dioxide, and nitrogen is 1:2:8;

[0025] (5) Ventilate...

Embodiment 2

[0029] The only difference between this example and Example 1 is that in the step (1) 60Co-γ rays are used to sterilize the tea leaves for 4 hours.

Embodiment 3

[0031] The only difference between this example and Example 1 is that in the step (1) 60Co-γ rays are used to sterilize the tea leaves for 5 hours.

Abstract

The invention provides a fresh-keeping method of orange Pu'er tea. The fresh-keeping method comprises the following steps: performing radiation sterilization treatment on tea leaves by utilizing 60Co-gamma rays; then performing secondary water removal, putting dehydrated tea leaves in a microwave water removing machine for water removal again and simultaneously introducing mixed gas to keep for 24-30 hours. The fresh-keeping method provided by the invention has the benefits that the moisture content of the tea leaves is stable, the freshness of the tea leaves is kept, and the moisture of the tea leaves is locked; therefore, in the making process of the tea leaves, the tea leaves still have good color and luster in the case of long-term preservation.

Description

technical field [0001] The invention relates to a tea storage technology, in particular to a fresh-keeping method for citrus tea. Background technique [0002] With the improvement of people's quality of life, the enhancement of health care awareness and the increase of demand for high-quality products, the output and output value of high-quality citrus tea are increasing year by year. However, tea is a product that is produced seasonally and consumed throughout the year, especially citrus tea is mainly produced in the rainy and high-humidity spring, if it is not kept fresh, citrus tea will soon lose its proper quality and flavor and health effects. At present, most of the fresh-keeping methods applied to citrus tea are single-factor fresh-keeping measures such as dehumidification, oxygen removal, and antibacterial, and the effect is not ideal. In particular, the specific technical parameters of each fresh-keeping technology are difficult to control and lack practical opera...
