Abstract

The invention relates to chestnut flower composite tea drink and a preparation method thereof. The chestnut flower composite tea drink is prepared by mixing 40 to 95 percent of original extract solution of chestnut male inflorescence, green tea or black tea and dry chrysanthemum, 1 to 8 percent of white granulated sugar, 0.01 to 0.15 percent of nitric acid, 1 to 3 percent of honey, 0.03 to 0.08 percent of xanthan gum, 0.02 to 0.08 percent of sodium carboxymethylcellulose and the balance of water, preprocessing, crushing, lixiviating, centrifugally filtering, performing colloid grinding, homogenizing, sterilizing and encapsulating. The chestnut flower composite tea drink is lixiviated ultrasonically, has a certain health-care function, meets requirements of general consumers on mouthfeel, effects and the like, and has wide market prospect; the yield of active ingredients such as flavone and the like is greatly increased; and pigment, preservative and essence are not added.

Description

technical field [0001] The invention relates to a chestnut flower compound tea beverage and a preparation method thereof. Background technique [0002] my country is the main chestnut producing country in the world, and its output accounts for 70% of the world's total output. Due to the high edible quality of Chinese chestnuts, they are welcomed by the international market and are known as "Pearls of the Orient". In addition, chestnuts have strong adaptability to climate and soil, are resistant to drought and barrenness, and can grow in large numbers on barren mountains and beaches, making them a In many areas, the structure of the planting industry has been adjusted, and the economic tree species of choice for farmers to increase their income and become rich has been planted in large quantities. Therefore, the chestnut industry occupies an extremely important position in my country's forestry and fruit tree industry. [0003] Chestnut belongs to the same plant with differen...
