Problems solved by technology

Although these leaf (bud) teas have better health care effects, it is difficult to pluck and keep fresh the fresh leaves (buds) of Pistacia chinensis, and the tea leaves (buds) of Pistacia chinensis alone are sour and astringent, the taste of medicine is heavier, and the taste is poor, so it is difficult to use them so far. large-scale promotion

Abstract

The invention discloses a processing method of pistacia chinensis bunge green tea. The pistacia chinensis bunge green tea is prepared by compounding dry pistacia chinensis bunge extract powder with green tea according to a mass ratio of 1 : (50-100). The processing method comprises the following steps: (1) proportioning the dry pistacia chinensis bunge powder and the green tea according to the mass ratio of 1 : (50-100); (2) performing mixing adsorption on the dry pistacia chinensis bunge powder and the green tea; (3) drying a mixture at 50-60 DEG C until the water content is not more than 7%; (4) packaging to obtain the pistacia chinensis bunge green tea. The processing method has the beneficial effects that the pistacia chinensis bunge leaf or bud extract is mixed with the green tea to prepare the pistacia chinensis bunge green tea; the medicinal value of pistacia chinensis bunge can be organically combined with the function of the green tea, the difficulty of separate tea making of pistacia chinensis bunge leaves is overcome, and the sour and astringent mouth feel and the medicinal fragrance of the pistacia chinensis bunge during separate tea making can be improved.

Description

technical field [0001] The invention relates to a processing method of pistachio green tea, which belongs to the technical field of drinking food processing. Background technique [0002] Pistacia chinensis is a deciduous woody plant of Anacardiaceae, and it is one of the main species of woody bioenergy with multiple uses. Pistacia chinensis is also known as medicine tree and medicine tree. It is a traditional medicinal plant. It is bitter and cold in nature. It has heat, analgesic, antibacterial and anti-inflammatory effects, and can be used to treat oral ulcers, sore throat, dysentery, diarrhea, and gonorrhea. Buds and inflorescence parts of Pistacia chinensis are used as wild edible vegetables. The leaves of Pistacia chinensis contain a large amount of polyphenols and flavonoid active substances such as gallic acid, quercetin, m-gallic acid, quercetin, 6-0-galloyl arbutin, which have heat-clearing and detoxifying, anti-oxidation, anti-mutation, and anti-inflammatory pro...
