example 1

[0022] Example 1: Spring production method

[0023] 1. Raw material of fresh leaves: picking soft kudzu leaves, the standard for picking young buds and leaves of tea trees is 2-3 leaves or single leaves per bud.

[0024] 2. Natural withering: Put kudzu leaves and young tea tree buds and leaves indoors, avoid direct sunlight, spread them on bamboo mats, the thickness of which is 4-6 cm, and wither at natural temperature, because kudzu leaves have a green smell It is relatively heavy, so kudzu leaves wither for a long time, 2-3 hours, and young buds and leaves of tea trees wither for 1-2 hours;

[0025] 3.) mechanical leaf homogenization: 60% (weight ratio) kudzu leaves after natural withering, and 40% (weight ratio) tea tree young shoots are put into the leaf homogenizer simultaneously, and mechanically mixed to make it become Compound tea product.

[0026] 4. Hot air withering: put the compound withered leaves into the hot air withering machine at 36-38°C and wither for 4-6 ...

example 2

[0035] Example 2: The production method of summer and autumn

[0036] 1. Raw materials of fresh leaves: Due to the high temperature in summer and autumn, the buds and leaves are easy to age and have a strong bitter taste, so the raw materials should be picked from tender kudzu leaf buds, and the standard for picking young and tender buds and leaves of tea trees is 2-3 leaves per bud.

[0037] 2. Natural withering: put kudzu leaf buds and tea tree young buds and leaves indoors, spread them on bamboo mats respectively, with a thickness of 4-5 cm, and wither at natural temperature. The kudzu leaf withering time is 2 hours. The withering time of young shoots and leaves is 1 hour;

[0038] 3. Mechanical leaf homogenization: Due to the bitter taste and poor taste of kudzu leaves in summer, the weight ratio of kudzu leaves is set at 40%, and the weight ratio of young tea buds and leaves is 60%. Mix to make it a compound tea product.

[0039] 4. Hot air withering: Due to the high te...

[0049] Example 3: The hygienic quality of kudzu leaf black tea produced by this process:

[0050] It is shown from the test report in Table 1 that none of the 9 pesticide residues were detected in the kudzu leaf black tea, the heavy metal lead content was only 0.8 mg / Kg, and the rare earth content was only 0.6 mg / Kg. In addition, after sensory evaluation, the overall quality of Geye black tea is equivalent to the first-grade Keemun black tea in terms of color, aroma and shape, and complies with the D1334 / T1086-200G standard. Therefore, it is considered that the quality and hygienic quality of the kudzu leaf black tea produced by this process can meet the standard of drinking tea.

Abstract

The invention discloses black tea with leaves of lobed kudzuvine and a processing method thereof. The black tea with the leaves of lobed kudzuvine is made by the leaves of lobed kudzuvine and tender shoots and leaves of tea trees through mixing and processing. The processing method of the black tea with the leaves of lobed kudzuvine sequentially comprises the following steps that the leaves of the lobed kudzuvine and the tender shoots and leaves of the tea trees are taken, are respectively subjected to natural withering and hot air withering and then are rolled after being evenly mixed according to the mass ratio of 6:4 or 4:6, and deblocking, amyloglucosidase fermentation, roll forming, shaping, shape fixing and microwave fragrance strengthening are performed after rolling. The nutrient substances in the leaves of the lobed kudzuvine and the tender shoots and leaves of the tea trees are mutually penetrated and organically integrated, and unique fragrance is produced after joint fermentation, so that a product is richer in nutrition and has the health maintenance and care effects and the anti-aging and human immunity enhancing roles.

Description

technical field [0001] The invention relates to the field of health-care black tea processing, in particular to a kudzu leaf black tea and a processing method thereof. Background technique [0002] Pueraria is a leguminous plant. "Compendium of Materia Medica" records: Pueraria is wild, and there are domestic species. It spreads long, and its leaves have three tips, which are as long as maple leaves. At present, most of the utilization of Pueraria plants is to wash the Pueraria root and squeeze the Pueraria powder Edible, and has certain nutritional and health care functions. But a large number of leaves are left on the vines as waste discarded. Studies have shown that kudzu leaves contain biochemical substances such as puerarin, daidzin, carotin, starch, and glucoside, which have good nutrition and health care. However, due to the special smell of kudzu leaves, the kudzu leaf tea made by ordinary frying and drying will have a bitter and astringent tea soup after brewing, an...
