Problems solved by technology

However, these components are unstable and are easily oxidized by oxygen or other oxides in the air and lose their activity
The utilization of tea leaves can be divided into direct soaking for drinking and extraction of active substances in tea leaves. Existing extraction methods for tea active ingredients can only extract water-soluble substances or fat-soluble substances alone, which is a serious waste of resources.

Embodiment 1

[0018] The microencapsulated tea extract is used in the processing of food or the preparation of health care products or in medicine.

[0019] The preparation method of microencapsulated tea extract comprises the following steps:

[0020] 1) Pretreatment: crush the green tea and pass through a 200-mesh sieve, add 15 times distilled water for pre-soaking for 3 hours;

[0021] 2) Water extraction: Add 0.001 times the volume of ethanol to the pretreated tea mixture, heat at 45°C for 2 hours, filter to obtain the filtrate and filter residue, concentrate the filtrate to 1 / 8 of the original volume to obtain the water extract, and remove the filter residue Dry to obtain tea leaves;

[0022] 3) Supercritical CO 2 Extraction: The tea leaves are subjected to supercritical CO 2 Extraction, CO 2 The flow rate is 35kg / h, the feeding amount of tea leaves is 80g, the extraction temperature is 35°C, and the extraction pressure is 40MPa; the separation temperature in the first stage is 45°...

Abstract

The invention discloses use of a microencapsulated tea extract in the aspects of processing of food, preparation of health care products, or medicines. A preparation method of the microencapsulated tea extract comprises the steps of pretreatment, water extraction, supercritical CO2 extraction and microemulsion microencapsulation. The method provided by the invention is simple to operate; the waterextraction is combined with the supercritical CO2 extraction, so that water-soluble components and liposoluble components in tea are extracted at the same time, the extraction efficiency is high, andtea resource is fully utilized. By adopting a microencapsulation technique, the surface tension between two phases in microemulsion is significantly reduced, the two extracted incompatible componentsare mixed into the homogeneous microemulsion, and the properties of the microemulsion are enabled to be stable, so that the economic value the microemulsion is improved.

Description

technical field [0001] The invention belongs to the field of plant component extraction, in particular to the application of microencapsulated tea extract. Background technique [0002] Tea was the good wood of South China originally, and tealeaves is as a kind of famous health drink, and it is the contribution of ancient China south people's cooking culture to China, is also the contribution of Chinese people to world's cooking culture. In the era of the Three Emperors and Five Emperors, there was a story about Shennong using tea to detoxify. The Yellow Emperor was named Ji and named Tu. Tea belongs to the Theaceae family and is an evergreen shrub or small tree plant with a plant height of 1-6 meters. Tea trees like a humid climate and are widely cultivated in the south of the Yangtze River Basin in my country. The leaves of the tea tree are made into tea leaves and used after soaking in water, which has the effects of strengthening the heart and diuresis. [0003] Tea c...
