Problems solved by technology

Since the selenium in this kind of tea has not undergone biotransformation at all, there is a great potential safety hazard, so it is not suitable for drinking
In addition, the production process of some teas is not proper, which will also lead to the loss of selenium in tea.

Embodiment 1

[0017] Embodiment 1: Select a sunny day, mix 45kg of water with 100 grams of humic acid selenium and titanium fertilizers per mu, spray the leaves of tea trees in Jiukeng with a fine mist, and after 12 days of fertilization and complete the picking of fresh leaves before and after Grain Rain, the picked fresh leaves Leaves are made into green tea according to the following process steps:

[0018] 1. Material selection

[0019] The standard for fresh leaves is that they are all composed of single buds, uniform in length, free of purple buds and insect buds, and meet the requirements of tenderness, uniformity, freshness and cleanliness.

[0020] 2. Spread to dry

[0021] Spread the fresh leaves in the bamboo plaque in time to let it lose water slightly. The spreading time is 3 to 4 hours, and it is turned 1 to 2 times in the middle to reduce the moisture content to 55 to 65%.

[0022] 3. Finished

[0023] Use the 6CST-50 type roller degreening machine to finish greening. When...

Embodiment 2

[0032] Embodiment 2: method is the same as embodiment 1, and difference is that the tea plant of selected test is Fuding Dabai, and its method and technical parameter are with embodiment 1.

Abstract

The invention discloses a production method for selenium-enriched green tea. Selenium content in green tea can be significantly increased by utilizing the production method. The production method is implemented through the following technical scheme: spraying mixture of 100g of humic acid selenium titanium fertilizer and 40-50kg of water to tea tree leaf surface per mu before tea picking, and 8-15 days after fertilization, finishing fresh leaves picking. The production method comprises the following steps of: 1) spreading and airing for 3-4 hours; 2) carrying out enzyme deactivation at temperature of 285-340 DEG C for 55-65 seconds; 3) tidying tea strip at 220-240 DEG C for 3-5 minutes; 4) reshaping at 185-195 DEG C and gently pressing for 55-65 seconds; 5) drying at 75-195 DEG C twice, 9-11 minutes each time; and 6) refining: spreading dried tea, removing stalks, and sieving and finally packaging. The prepared green tea has high selenium content and emerald green color and luster.

Description

[0001] technical field [0002] [0003] The invention relates to a method for increasing crop trace elements, in particular to a method for increasing organic selenium content in tea leaves. [0004] Background technique [0005] [0006] With the improvement of people's living standards and health awareness, people not only gradually increase the demand for tea quantity, but also continuously improve the quality requirements of tea. It is hoped that the content of some trace elements beneficial to human body in tea can be increased. For example, selenium is an essential trace element for the human body. Selenium-rich foods have many benefits for the human body, such as increasing immunity, preventing cancer, preventing cardiovascular and cerebrovascular diseases, and preventing diabetes. The Chinese Nutrition Association recommends that the per capita daily selenium intake is 50-200 micrograms, but my country is a big selenium-deficient country. Now the daily selenium i...
