Preparation method of health-care mulberry leaf tea

Abstract

The invention provides a preparation method of health-care mulberry leaf tea. The preparation method comprises the following steps of picking high-quality fresh mulberry leaves, cleaning the picked mulberry leaves with distilled water, performing sunning, and performing spreading; performing steam fixation treatment, and performing pan-frying treatment so as to obtain mulberry leaf tea primary semifinished products; compounding a mixture containing Chinese junipers, argy wormwood, aloe and licorice roots, performing crushing, adding an ethanol solution, performing leaching treatment, performing filtration so as to obtain extract, and performing heating and concentrating until the mass is 1 / 2 of original mass; uniformly spraying the concentrated extract onto the mulberry leaf tea primary semifinished products, and performing turning over while spraying; and rolling processed mulberry leaf tea at the temperature of 50-60 DEG C for 20-40min, performing freeze drying at the temperature being minus 20-minus 10 DEG C for 20-30min, and performing crushing so as to obtain the health-care mulberry leaf tea.

Description

technical field

[0001] The invention relates to the technical field of preparation of mulberry leaf tea, in particular to a preparation method of health-care mulberry leaf tea. Background technique

[0002] Mulberry leaf is the king of plants. It has the reputation of "Ginseng is hot and nourishing, and mulberry leaf is clear and nourishing". It is rich in 17 kinds of amino acids, crude protein and crude fat. The food hygiene organization listed it as "one of the top ten health foods for human beings in the 21st century" and became a source of green new food for human beings. Mulberry leaf tea generally uses high-quality tender mulberry leaves with superior ecological environment and no pollution as raw materials, and is refined through scientific baking and other processes. In the process, it is more important to remove the bitterness and astringency of organic acids in mulberry leaves; the characteristics of sweet taste and delicate fragrance are also important.
