Embodiment 1

[0031] A preparation method of selenium-enriched black tea, comprising the following steps:

[0032] Step 1. Selection of tea plantation site: select weakly acidic soil parent rock soil, and plant tea at an altitude of 1800-3000 meters;

[0033] Step 2, pre-cultivation technology: after planting, add selenium-enriched tea enzymes to treat the tea leaves in the early-stage topdressing after planting, and apply selenium-enriched foliar fertilizer;

[0034] Step 3, tea picking: picking for the first time, picking tea at 5-6 in the morning, all picking by hand, picking tea leaves of uniform size;

[0035] Step 4, fresh leaf sorting: pick out the impurities in the fresh leaves, and classify the fresh leaves;

[0036] Step 5. Fixing: Use high temperature to destroy the enzymes of fresh leaves, evaporate the water in fresh leaves, and use a drum fixing machine to fix the greens. The temperature of the cylinder is controlled at 250 ° C, and the fixing time is 5 minutes;

Abstract

The invention discloses a preparation method of selenium-enriched black tea. The preparation method comprises the following steps of selecting tea planting land; carrying out early-stage cultivation technology, specifically, adding selenium-enriched tea enzyme to treat tea in early-stage topdressing after planting, and applying selenium-enriched foliar fertilizer; picking tea leaves for twice, carrying out tea picking at 5-8 o'clock in the morning, carrying out manual picking on all the tea leaves to obtain the tea leaves with the uniform size; fresh leaf spreading; carrying out deactivation of enzymes; selenium-enriched nutrient solution spraying; kneading; fermenting; drying and the like. The selenium-rich black tea prepared by the preparation method of the selenium-rich black tea is rich in selenium content and good in quality, and meanwhile, the prepared black tea has the health-care effects of clearing away heat and toxic materials, invigorating the stomach, promoting digestion, clearing intestines, disinfecting and the like.

Description

technical field [0001] The invention relates to the technical field of tea production technology, in particular to a production method of selenium-enriched black tea.
