Abstract

The invention relates to a production process of a herbal concentrated solution, and belongs to the technical field of a herbal extract product, which aims at solving the technical problem for improving the herbal extraction efficiency, guaranteeing the health and sanitation of a herbal product and maximally maintaining herbal fragrant substances. According to the technical solution, the process comprises the following steps: crushing, multifunction extracting, separating and purifying, low-temperature concentrating and sterilely cold filling, wherein in the multifunction extracting step, the extraction of a tank group and supercritical extraction are combined, when in the tank group extraction, the fragrance is recovered, the recovered fragrant substances can be dried in a freezing manner to obtain liquid herbal essence which is used for filling the herbal extract concentrated solution, so that the fragrant substances in the herbal extract solution are maximally maintained, characteristics of color, fragrance and taste of the herbs can be sufficiently maintained, and the problem that the herbal extraction product is low in fragrance can be effectively solved.

Description

technical field [0001] The invention relates to a production process of herbal concentrate, which belongs to the technical field of production of herbal extract products. Background technique [0002] At present, the extraction processes of herbs (such as tea) mainly include water extraction and organic solvent extraction; among them, water extraction has low extraction efficiency and poor economic benefits due to the oxidation of active ingredients of herbs due to high extraction temperature and long time; There will be residues in the product of organic solvent extraction, which reduces the quality of the extract, and the equipment investment 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 loss of aroma is serious. A strong herbal aroma can be smelled during the extraction stage, resulting in the lack of fresh aroma of herbal extracts and concentrates (such as tea concent...

Problems solved by technology

[0002] At present, the extraction processes of herbs (such as tea) mainly include water extraction and organic solvent extraction; among them, water extraction has low extraction efficiency and poor economic benefits due to the oxidation of active ingredients of herbs due to high extraction temperature and long time; There will be residues in the product extracted by organic solvent, which reduces the quality of the extract, and the equipment investment is large, and the process is relatively dangerous

Moreover, there is also a lack of recovery devices for aroma on the extraction production line, the loss of aroma is serious, and a strong herbal aroma can be smelled during the extraction stage, resulting in the lack of fresh aroma of herbal extracts and concentrates (such as tea concentrates)

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
