Problems solved by technology

[0002] Tea has increasingly become a health-care drink in our daily life, but both green tea and black tea contain central stimulants such as caffeine and theophylline during drinking, which affect sleep and have toxic side effects on vital organs such as the heart and brain. The alkaloids in tea can also neutralize the acidic substances in the stomach and affect the function of the stomach, making it inconvenient to drink in large quantities for a long time

Embodiment approach 1

[0014] 1. Tea leaves (green tea or black tea) 50 o Ultrasonic water extraction in C;

[0015] First use 10 kilograms of tea leaves, 100 kilograms of water and tea leaves at 50 o Ultrasonic water extraction in C, filtering to obtain the first water extract, combining the same two extracts to obtain the water extract, adjusting the pH value to 3-4 with acetic acid to obtain the sample solution.

[0016] 2. Use a nonlinear method to load the sample;

[0017] The loading column is the first 10LPIPO-00 high-pressure column and the second 10L732 strong acid cation exchange resin high-pressure column connected in series, and the above-mentioned loading solution is uploaded to the first PIPO-00 column as far as possible until obvious deep The yellow liquid was eluted with 60 kg (column volume) of water until the end of the first column overflowed.

[0018] 3. Separate elution treatment;

[0019] The first PIPO-00 column was eluted with 50L of 95% ethanol, the ethanol was recovered...

Abstract

The invention relates to a technological method for preparing instant tea without alkaloid components including caffeine and theophylline etc. The technological method belongs to the field of extraction, separation and purification of a tea (a green tea and a black tea). The tea is separated and purified through a macroreticular resin PIPO-00, an advanced asymmetric chromatographical idea is adopted, double-column sampling and chromatography at high pressure are carried out, the components with excitatory effects including the caffeine and the theophylline etc. in the tea are removed, and an instant tea product with functional health care components including either tea polyphenol or theaflavin etc. in the tea is obtained. The components including the caffeine and the theophylline are removed, and the functional health care components including the either tea polyphenol in the green tea or the theaflavin in the black tea etc. are preserved, the product can be instantly dissolved and convenient to use, dosage of the product is improved and range of crowds is enlarged, so that the instant tea is a health care product for patients of all ages and both sexes.

Description

technical field [0001] The patent of the invention relates to a process for preparing instant tea that does not contain alkaloids such as caffeine and theophylline, and belongs to the field of extraction, separation and purification of tea leaves (green tea and black tea). The macroporous adsorption resin PIPO-00 is used for separation and purification, and the advanced asymmetric chromatography concept, double column loading, high-pressure chromatography, eliminates the excitatory components such as caffeine and theophylline in tea, and obtains the retained tea. Instant tea products with functional health ingredients such as tea polyphenols or theaflavins. Background technique [0002] Tea has increasingly become a health-care drink in our daily life, but both green tea and black tea contain central stimulants such as caffeine and theophylline during drinking, which affect sleep and have toxic side effects on vital organs such as the heart and brain. The alkaloids in tea c...
