Tea product production technology

Abstract

The invention relates to a tea product production technology, and belongs to the technical field of tea extract product production. The tea product production technology aims at achieving the technical purposes of improving tea leaf extraction efficiency, guaranteeing health of tea products and retaining aroma substances of tea leaves to the maximum degree. According to the technical scheme, the technology includes the following steps of crushing, multifunctional extraction, separation and purification and low-temperature concentration. A tea leaf extraction concentrated solution obtained after low-temperature concentration can be made into instant tea powder through freeze-drying and can also be made into a tea concentrated solution through cold aseptic filling; pot group extraction and supercritical extraction are combined in the step of multifunctional extraction, aroma recovery is performed in pot group extraction, and recovered aroma substances can be directly added into the tea leaf extraction concentrated solution in a backfilling mode and can also be made into liquid tea essence in a freeze-drying mode to be added into the tea leaf extraction concentrated solution, so that the flavor substances in the tea leaf extraction solution are retained to the maximum degree, the color, aroma, taste and other characteristics of tea are fully maintained, and the problem that tea leaf extract products are insufficient in aroma is effectively solved.

Description

technical field [0001] The invention relates to a production process of tea products, which belongs to the technical field of production of tea extract products. Background technique [0002] At present, the tea extraction process mainly includes water extraction and organic solvent extraction; among them, water extraction has low extraction efficiency and poor economic benefit due to the high extraction temperature and long time, and the oxidation of the active ingredients of tea leaves causes odor change; organic solvent extraction There will be residues in the product, which reduces the quality of the extract, and the investment in equipment is large, and the process is relatively dangerous. Moreover, there is also a lack of aroma recovery devices on the extraction production line, and the aroma loss is serious. A strong tea aroma can be smelled during the extraction stage, resulting in a lack of fresh aroma in tea extracts, concentrates, and powder products. In addition...

Problems solved by technology

[0002] At present, the tea extraction process mainly includes water extraction and organic solvent extraction; among them, water extraction has low extraction efficiency and poor economic benefit due to the high extraction temperature and long time, and the oxidation of the active ingredients of tea leaves causes odor change; organic solvent extraction There will be residues in the product, which reduces the quality of the extract, and the investment in equipment is large, and the process is relatively dangerous

Moreover, there is also a lack of aroma recovery devices on the extraction production line, and the aroma loss is serious. A strong tea aroma can be smelled during the extraction stage, resulting in a lack of fresh aroma in tea extracts, concentrates, and powder products.

In addition, the extract is simply filtered to remove the residue, and does not fully remove harmful substances such as pesticide residues, resulting in the final extract product is not conducive to health
