Embodiment 1

[0018] Embodiment 1: Step 1, selection: select fresh, crisp and tender celery, remove the rhizome and only keep the leaves, rinse with clean water, and cut into 3cm long sections;

[0019] Step 2, blanching: adjust the pH of the hot water to 7 with 0.02% Na2CO3 solution, and heat it to 85°C to blanch the selected celery for 3 minutes;

[0020] Step 3, crushing: crush the blanched celery in step 2, and use a strainer to filter to obtain celery juice, set aside;

[0021] Step 4. Centrifugation: Use a high-speed centrifuge to centrifuge the celery juice. The speed of the centrifuge is 4000r / min, and the centrifugation time is 10 minutes. During the centrifugation process, add salt, sodium alginate, honey and citric acid, celery juice, salt, lemon The weight-number ratio of acid, sodium alginate and honey is: 30:1:1:1:1;

[0022] Step 5. Processing: put celery juice into a sphere made of propolis, put old tea and propolis balls into a tea bag to form new green tea, and the weight...

Abstract

The invention discloses a green tea processing process in the technical field of tea processing. The green tea processing process comprises steps as follows: S1, sorting: fresh and brittle celery is selected, rhizomes are removed, and only celery leaves are retained, washed clean with clean water and cut into segments which are 3-5 cm long; S2: blanching: pH of hot water is adjusted to range from 7 to 8 with a 0.02%-0.05% Na2CO3 solution and heated to 85-95 DEG C to blanch the selected celery for 3-5 min; S3: crushing: the blanched celery in S2 is crushed and filtered with a filter net, and celery juice is obtained and left to stand; S4, centrifugal treatment: the celery juice is subjected to centrifugal treatment with a high-speed centrifuge, salt and citric acid are added in the centrifugal process, and the weight ratio of the celery juice, the salt and citric acid is 30:1:1; S5: processing: the celery juice is packaged in a ball made of propolis, aged tea and propolis balls are added to a tea bag, and novel green tea is formed. With the adoption of the scheme, the tea water obtained after the aged tea is brewed is light green.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a green tea processing technology. Background technique [0002] Green tea is one of the six major tea families in China. It is a tea drink made without fermentation. It retains the natural substances of fresh leaves and contains tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. Also more. These natural nutrients in green tea have special effects on anti-aging, anti-cancer, anti-cancer, sterilization, and anti-inflammatory. [0003] When the new green tea is first brewed, the tea water is light green, and it will turn slightly yellow as the time in the cup prolongs. After the green tea is placed for a long time, the new tea is easily oxidized and becomes old tea. The color of the tea brewed with such tea can range from light yellow to dark yellow, thus losing the green color of the tea, while the nutrients in the tea are still ...
