Abstract

The invention discloses a preparation method for a tea extract, belonging to the technical field of extraction of effective components of tea leaves. The preparation method comprises the following steps: firstly, carrying out low-temperature rapid freezing treatment on high-quality commercial tea leaves; then immediately crushing; then combining a high-voltage pulsed electric field (PEF for short) technology, an ultrasonic treatment technology and a low-temperature enzymolysis technology; and carrying out low-temperature extraction in a whole process. According to the preparation method for the tea extract, the loss of effective components, caused by high-temperature processing, is avoided, and the extraction rate of the effective components of the tea leaves is also improved. The process is simple and low in cost; the introduction amount of extraneous food additives, processing auxiliary agents and chemical substances is reduced; the natural nutritional ingredient and the flavor of the tea leaves are kept to the greatest extent, the low-carbon production is realized and the environment is protected.

Description

technical field

[0001] The invention relates to the extraction of effective components of tea, in particular to a preparation method of tea extract. Background technique

[0002] Tea is the largest beverage in the world except water. Tea contains a variety of biologically active substances, such as tea polyphenols, theanine and caffeine. A large number of studies have shown that tea polyphenols have biological activities and pharmacological effects such as anti-oxidation, scavenging free radicals, lowering blood pressure, lowering blood fat, anti-radiation, anti-cancer and anti-cancer. Caffeine has the functions of stimulating the cerebral cortex, enhancing the immune function of the body, strengthening the heart and diuresis, etc., while tea polysaccharide has pharmacological effects such as lowering blood fat, lowering blood pressure, lowering blood sugar and enhancing immune function. Therefore, it is safe and effective from tea. Extracting and separating tea polyphenols...
