Problems solved by technology

With the broad development prospects of peony seed oil, more people are invested in the production of peony seed oil, but the production method of peony seed oil mainly uses supercritical CO 2 extraction techniques, although supercritical CO 2 Extraction technology is an ideal method, which has the advantages of strong extraction capacity, high extraction rate, and good product quality. However, it must be carried out under ultra-high pressure conditions above 25Mpa, and the extremely high pressure limits the expansion of the effective volume of the equipment.

Abstract

The invention relates to the technical field of peony seed oil extraction, in particular to a subcritical production method for peony seed oil extraction. The subcritical production method comprising the following steps: (1) peeling peony seeds and crushing; (2) completing primary resolving; (3) completing secondary resolving; (4) preparing peony seeds crude oil; (5) degumming through a hydration method; (6) deacidifying through a high temperature sparse soda method; (7) decolorizing with activated clay; (8) performing steam distillation for deodorization to obtain finished oil. According the subcritical production method, mass production of the peony seeds is realized, and not only are solvent consumption and production cost low, but also the quality of obtained meal is good, so that residues are fully utilized, and resources are saved. The current subcritical extraction technology is an efficient, low-consumption, environment-friendly and safe extraction technology with a wide application prospect, is widely applied to extraction and separation of pharmaceutical intermediates, fat-soluble pigments and volatile flavor and fragrance, is in a leading level in the domestic extraction industry, and represents the latest technological development direction.

Description

technical field [0001] The invention relates to the technical field of peony seed oil extraction, in particular to a production method for extracting peony seed oil by subcriticality. Background technique [0002] Peony seeds are the crystallization of the essence of peony plants. In addition to inheriting all the characteristics of peony itself, they also have their own unique medical and nutritional values. Tests by many professional institutions such as Jiangnan University, China Grain and Oil Quality Supervision and Inspection Center, an authoritative department of oil and fat, show that the unsaturated fatty acid content of peony seed oil is more than 90%, and the most commendable is that the polyunsaturated fatty acid-α-linolenic acid content exceeds 40%. %, 140 times that of olive oil, analysis experts exclaim that this is "the best oil in the world". Mr. Zhao Xiaoqing, the "father of peony oil", was the first to develop peony seed oil series products. After more tha...
