Abstract

The present invention discloses a deterioration preventing blueberry milk tea and a preparation method thereof. The preparation method comprises the following steps: 1) soaking tea leaves, corn stigma, pueraria lobata flowers, gardenia jasminoides, blueberries, rosa laevigata root and lotus leaves in water to obtain a soaking solution; 2) extracting the soaking solution with an extracting agent, and removing the extracting agent to obtain tea powder; 3) mixing the tea powder, white sesame powder, milk powder, radix puerariae powder, red bean powder, white granulated sugar, vanillin and sodium carboxymethyl cellulose to prepare the blueberry milk tea powder; and 4) boiling the milk tea powder in water to obtain the deterioration preventing blueberry milk tea. The deterioration preventing blueberry milk tea powder contains a high concentration of tea polyphenols and thus the milk tea powder can be preserved for a long-term without deterioration.

Description

technical field [0001] The present invention relates to milk tea powder, in particular, to a milk tea powder. Background technique [0002] Milk tea is a beverage mixed with milk and tea. The main components of milk are water, fat, phospholipids, protein, lactose, and inorganic salts, which are rich in nutritional value; while tea can reduce the risk of cardiovascular disease and cancer, mainly because green tea It is rich in flavonoids, especially tea polyphenols. A large number of clinical experiments have proved that tea polyphenols have cell regulation and antioxidant functions. Tea polyphenols are a general term for a class of highly active flavonoids, which are found in high content in tea. Of course, tea not only has cell regulation and antioxidant functions, but also has the effect of losing weight; for example, Unilever found in two clinical experiments on the efficacy of high content of tea polyphenols in tea, without changing diet and physical activity. , Mildl...
