Technical Field

The invention relates to a beverage, in particular to a water shield health-care beverage taking natural water shield as a main raw material.

Background

The water shield, also called as water chestnut and lake vegetable, belongs to the Nymphaeaceae, is a wild floating-leaf plant for many years, the leaves are oval and dark green, the back surface secretes mucus similar to agar, and the water shield contains various components such as rich protein, glucose, carbohydrate, fat, various vitamins and mineral substances, not only is a unique precious vegetable with unique flavor, but also has the effects of clearing heat, moistening lung, promoting urination, reducing swelling, detoxifying, invigorating stomach, checking diarrhea, reducing blood sugar and the like, and has the health-care function of medicine and food. At present, the water shield is utilized only by primary processing and prepared into simple cans which are sold to nationwide places, exported to Japan, Korea and the like. Until now, water shield has not been deeply processed to manufacture products with high added value. The main problems in the development of the water shield industry at the present stage are as follows: extensive management, low technological content, no formation of self-unique brasenia schreberi culture and the like. Therefore, the development of cheap and efficient water shield products with high added value is a key problem to be solved urgently.

At present, people pay more attention to processing water shield into water shield beverage, but most of the invention patents published at present are that water shield is subjected to enzyme deactivation, and then the water shield is subjected to long-time high-temperature treatment sterilization treatment, so that the nutritional value of the water shield is damaged.

Disclosure of Invention

Aiming at the existing problems, the invention aims to provide a natural water shield beverage which fully uses the active ingredients of water shield and can achieve the effects of effectively clearing heat, quenching thirst, sterilizing and disinfecting, and tonifying middle-jiao and Qi.
