Abstract

The invention relates to the field of subcritical extraction and injection, and particularly relates to a subcritical injection method of grape seed anthocyanidins, wherein the subcritical injection method is suitable for food, tobacco, medicine and food healthcare and other industries, has the advantages of simple process and low equipment investment, has relatively low pressure due to the fact that the whole process is performed under normal-temperature or low-temperature conditions, does not damage functional components of grape seed samples, anthocyanins and injected samples, and comprises the following steps: pretreating; sieving after drying and crushing; extracting; placing pretreated grape seeds into a subcritical extraction tank; injecting subcritical fluid as an extraction solvent; extracting under certain extraction conditions; desolventizing at a constant temperature and obtaining extracts containing the grape seed anthocyanidins after finishing extraction; placing the extracts and materials to be injected into a subcritical injection tank; adding an injection solvent; injecting under certain injection conditions; and desolventizing the injection tank at a constant temperature after finishing injection to obtain the materials after injection treatment.

Description

technical field [0001] The invention relates to the field of subcritical extraction and injection, and specifically relates to a method suitable for industries such as food, tobacco, medicine, food and health care. The process is simple and the investment in equipment is low. A subcritical injection method of grape seed anthocyanins that can damage grape seed samples, anthocyanins, and functional components injected into the samples. Background technique [0002] Grape seeds are rich in proanthocyanidins. Proanthocyanidins are polyphenolic mixtures that widely exist in nature, mainly composed of monomers, dimers, trimers...decamers of catechins. Among them, the two- to five-mer is oligomeric proanthocyanidin (OPC), which is famous for its high efficiency, low toxicity and high bioavailability. According to reports, OPC has a strong antioxidant capacity. In the body, its ability to resist oxidation and scavenge free radicals is 50 times that of Ve and 20 times that of Vc. ...
