Xiaoqing Citrus is the abbreviation of Xiaoqing Citrus Pu 'er tea, which belongs to the category of citrus Pu 'er tea together with the common "Dahong Citrus" (Chenpi Pu 'er tea). Orange peel can be divided into green orange peel (Xiaoqing orange), red orange peel and red orange peel according to the harvest time. Xiaoqing Citrus refers to the fruit of Chazhi Citrus harvested when it is physically immature. Xiaoqing orange is light green and shiny, with thick skin, full oil cavity and rich fruit fragrance. The citrus fruits of Xinhui Tea Branch Citrus in July and August were dug out, put into Yunnan cooked Pu 'er tea, and then dried or dried in the sun to obtain Xiaoqing Citrus Pu 'er tea.
Under normal circumstances, the shelf life of Xiaoqing orange is generally about 3 years. If you want to preserve Xiaoqing orange for a long time, you need to dehydrate it, so that Xiaoqing orange will taste better. With the passage of time, the longer the time, the stronger the fragrance of Xiaoqing orange will be.
Frost on the epidermis of small green orange
There may be a layer of hoarfrost on the surface of Xiaoqing citrus, which is not mildew, but the crystallization of citrus oil. Only citrus fruits with high volatile oil content can precipitate crystals of citrus oil under certain conditions, which is similar to the mechanism of frost formation in persimmon, plum and other fruits. This layer of white frost is a sugar-containing substance, which has a health-preserving effect similar to persimmon cream, and it is also white into the lungs and can moisten the lungs.
