Embodiment 1～3

[0049] Embodiment 1~3 different cultivation conditions obtain selenium-enriched fresh tea leaves

Embodiment 1

[0051] Production of selenium-enriched tea 1. In a tea production base in Jiangsu Province. Mix the Suzhou Selenium Technology nano-selenium plant nutrient with vermiculite to obtain a selenium-enriched nutrient, and apply it to the tea garden from July to August after the spring tea is harvested and pruned. The total amount of selenium applied to the tea garden is 10g / mu; ( 2) Mix the nano-selenium plant nutrient with tea tree fertilizer, and apply it to the tea garden in mid-November after autumn. The total amount of selenium applied to the tea garden is 40g / mu; (3) the nano-selenium plant nutrient is mixed with vermiculite to obtain a selenium-enriched nutrient, which is applied to the tea garden in late February, one month before the harvest of spring tea in the coming year, and applied to the tea garden The total selenium content is 20g / mu.

Abstract

The invention discloses a method for preparing a selenium-rich tea extract, which comprises the following steps 1) acquiring selenium-rich green tea leaves with stable selenium content, wherein the selenium content of the selenium-rich green tea leaves is 500-5000 mum gg; 2) taking the selenium-rich green tea leaves as an extracted raw material, deactivating enzyme and extracting to obtain the selenium-rich tea extract. The selenium-rich tea extract can fully reserve the original local flavor of the green tea, high selenium content is provided, and the requirements for daily selenium supplement of people can be satisfied.

Description

technical field [0001] The invention relates to the technical field of selenium-enriched tea extraction, in particular to a preparation method of selenium-enriched tea extract. Background technique [0002] Selenium, element symbol Se, is an essential trace element for the human body and is the active center of glutathione peroxidase (GSH-Px). It has biological properties such as anti-cancer, anti-aging (anti-oxidation), improving human immunity, and antagonizing heavy metals. The Chinese Nutrition Society recommends a per capita daily selenium intake of 50-200 micrograms. But now the daily selenium intake of adults in our country is only 26-32 micrograms, and selenium malnutrition is common in our country. In my country, 72% of counties (cities) have low selenium or lack selenium. Keshan disease and Kaschin-Beck disease occur in Heilongjiang, Inner Mongolia, Gansu, Qinghai, Sichuan and other areas seriously deficient in selenium. Some areas with high incidence of cancer a...
