Embodiment 1

[0019] On April 5, 2014, the applicant's research and development team picked the green and normal homogeneous leaves in the upper part of the grape branches, cleaned them with clean water; divided the leaves into three types of homogeneous leaves: old, medium and tender according to the color of the leaves; and then peeled off The petioles and thick veins are collected, and the petioles and thick veins are collected for later use, leaving only leaves with thin veins.

[0020] Then cut the leaves into small square leaves with a side length of 1 cm, place the small leaves on a spreading green tray for 2 hours, spread the thickness of 2 cm, and turn it gently every 30 minutes.

[0021] Then put the peeled petiole and thick leaf veins into the boiler, add water to cook, and use the steam generated in the boiler to complete the greening; put the small leaves on the conveyor belt of the steam greening machine, put them in at a constant speed, spread them evenly, and spread them afte...

Embodiment 2

[0026] On May 15, 2014, the applicant's research and development team picked the green and normal homogeneous leaves in the upper part of the grape branches, cleaned them with clean water; divided the leaves into three types of homogeneous leaves: old, medium and tender according to the color of the leaves; and then peeled off The petioles and thick veins are collected, and the petioles and thick veins are collected for later use, leaving only leaves with thin veins.

[0027] Then the leaves were cut into small square leaves with a side length of 2 cm, and the small leaves were placed on a spreading green tray for 2.5 hours, with a thickness of 2.5 cm, and gently turned once every 30 minutes.

[0028] Then put the peeled petiole and thick leaf veins into the boiler, add water to cook, and use the steam generated in the boiler to complete the greening; put the small leaves on the conveyor belt of the steam greening machine, put them in at a constant speed, spread them evenly, an...

Abstract

The invention discloses a processing and production method of grape-leave tea. The invention is characterized in that the processing and production method comprises the following nine major steps: picking the grape leaves, peeling the grape leaves, airing the enzymes, deactivating the enzymes, air-drying, kneading, screening and classifying, refining the aroma, dehydrating and the like. The processing and production method has the beneficial effects that the leaf stems and the thick leaf veins of the fresh and tender grape leaves which are picked in proper season are peeled, so that the refreshing and pure taste of the grape-leave tea can be preserved; enzymes in the leaf stems and the thick leaf veins are further deactivated by water vapor, so that the pure aroma of the grape-leave tea can be further ensured; the enzyme deactivation and the air-drying are performed on a conveyer belt so that the shapes of the grape leaves are kept and the strips formed by the grape leaves are uniform in shape; the kneading is performed when the grape leaves are hot, so that the grape leaves can be better shaped and the astringent taste of the grape leaves is removed; and the astringent taste can be further covered by the step of refining the aroma. The grape-leave tea produced according to the processing and production method has the advantages that the grape-leave tea is uniform in appearance, jade-green in color, refreshing and thick in aroma, dark-green and transparent in tea-soup color, tender and mellow in tea-soup taste as well as exquisite and fragrant tea-soup flavor. The processing and production method greatly improves quality of the grape-leave tea product.

Description

technical field [0001] The invention relates to the technical field of tea processing and production, in particular to a processing method of grape leaf tea. Background technique [0002] Grapes have high nutritional value, large grains, thick skin, juicy, easy to separate skin and flesh, sweet and sour taste, generally grow in clusters, and are yellow-green, red, black-blue or purple. There is a thin skin on the outside of the pulp, and a thin frost on the outside of the skin. Some varieties are seedless. Grapes can be used as raw fruit, wine or raisins.
