Description

A kind of green fruit green tea instant beverage and preparation method thereof

technical field

The invention belongs to the field of food processing, and in particular relates to an instant beverage of green fruit and green tea and a preparation method thereof.

Background technique

Qingguo is also called Jianguo, because it tastes astringent at the beginning, after a long chewing, it is sweet and delicious, with an endless aftertaste. It contains protein, fat, carbohydrates, dietary fiber, carotene, retinol equivalent, vitamin B1, vitamin B2, niacin, vitamin C, calcium, iron, phosphorus, magnesium, zinc, selenium and other ingredients. The green fruit tastes sweet and sour, flat in nature, has the functions of clearing away heat and detoxification, relieving throat and resolving phlegm, promoting body fluid and quenching thirst, appetizing and lowering qi, relieving restlessness and sobering up alcohol, suitable for treating sore throat, cough and vomiting blood, bacillary dysentery, epilepsy, summer heat and polydipsia, enteritis Diarrhea and other diseases. Green fruit oil also has the function of preventing and treating heart disease, gastric ulcer and protecting gallbladder. According to another study, it was found that green fruits, eaten by pregnant women and breastfeeding, can significantly promote the development of the baby's brain and make the baby smarter. Modern medical research has found that intake of calcium-rich substances can reduce the risk of colon cancer and rectal cancer. The calcium content of green fruit is quite high, and the ratio of calcium to phosphorus is much greater than 2. If eaten regularly, there is enough calcium in the human body to combine with fatty acids and bile acids to form insoluble compounds that are excreted from the body, reducing the carcinogenic effect on the intestinal tract.

At present, people have known the edible and medical value of green fruit, but seldom use green fruit as daily beverage raw material, more seldom see the report that green fruit cooperates with green tea to prepare green fruit green tea instant beverage.
