Abstract

The invention relates to the technical field of drink and particularly relates to a preparation method of longan tea. The method comprises the following steps of: 1) cleaning longan, peeling, breaking and performing ultrasonic extraction to obtain a longan extract; 2) fetching mangosteen, cleaning, peeling, adding water and performing microwave extraction to obtain a mangosteen extract; 3) uniformly mixing the longan extract and the mangosteen extract, and performing magnetization treatment to obtain magnetized liquid; and 4) filtering the magnetized liquid, performing ultrahigh-temperature instant sterilization and filling to obtain the longan tea. The longan tea prepared by the method has the functions of nourishing blood, replenishing spleen and eliminating fatigue and realizes a relatively good antioxidant effect.

Description

technical field [0001] The invention relates to the technical field of beverages, in particular to a preparation method of longan tea. Background technique [0002] Longan (Latin scientific name: Dimocarpus longan Lour.) is an evergreen fruit tree and tree of Sapindaceae Longan. Provinces such as Fujian, Guangdong, Guangxi and Taiwan are the main producing areas, and provinces such as Hainan, Yunnan, Sichuan and Guizhou are all cultivated. Longan invigorates the heart and spleen, nourishes qi and blood, invigorates the spleen and stomach, and nourishes muscles. Thinking of hurting the spleen, dizziness, insomnia, palpitations, palpitations, weakness, physical weakness after illness or postpartum, and blood loss due to spleen deficiency. Modern medical practice has proved that it also has the effects of beautifying and prolonging life. [0003] At present, when longan is on the market, it is mainly fresh food. However, due to the concentrated longan harvesting period, dif...
