Problems solved by technology

However, the method of high-temperature drying also has its own shortcomings. Too high temperature and some oxidation caused by contact with air will destroy the active ingredients in the tea to a certain extent, affecting the color, nutrition and taste of green tea powder
At present, there are also examples of using vacuum freeze-drying technology, but pre-freezing takes a long time to cool down to achieve the pre-freezing effect, which consumes time and energy in production

Abstract

The invention provides a green tea powder capsule and a preparation method thereof, and in particular, tea leaves after steaming are subjected to vacuum freeze drying and then are loaded into a capsule. The preparation method comprises the steps: pre-freezing the tea leaves after steaming in a liquid nitrogen quick-freezing device, then loading the pre-frozen tea leaves into a vacuum freeze drying box, heating up to 30+ / -5 DEG C at the step temperature of 0.5 DEG C per minute, drying, then crushing the freeze-dried tea leaves at low temperature into a powder, loading the powder into the capsule prepared from plant starch, and thus obtaining the green tea powder capsule.

Description

technical field [0001] The invention relates to a capsule, in particular to a vegetable starch capsule filled with green tea powder. Background technique [0002] Green tea powder is a kind of ultra-fine powdered green tea. It is emerald green in color and delicate. It maintains the original natural green color and nutritional and pharmacological components of green tea to the greatest extent. It can be widely used in beverages, food processing, cosmetics, medical and health products, etc. . Green tea powder contains many nutrients, including tea polyphenols, chlorophyll, amino acids, vitamins, tannic acid, folic acid, mineral elements, etc., making green tea powder have good antioxidant and sedative effects, which can reduce fatigue and prevent The efficacy of high blood pressure, diabetes, cancer and other diseases can also eliminate dark spots, wrinkles, freckles, chapped skin and other skin problems, and it can also promote slimming and body shaping. [0003] In recent...
