Abstract

The invention discloses an extraction method of peony seed oil. The extraction method concretely comprises the following steps of 1) soaking peony seeds into a concentrated table salt aqueous solution; 2) transferring the peony seeds into a vacuum vessel for puffing drying treatment; 3) crushing the dried peony seeds, and performing enzymolysis; 4) performing heating and thermal insulation on an enzymolysis material, performing centrifugal separation, collecting a supernatant, and then performing ultrafiltration membrane extraction to obtain peony seed crude oil; 5) mixing the peony seed crudeoil with monoethanolamine salt, and adding a lipase solution to obtain the peony seed crude oil after deacidification; and 6) performing heating reflux extraction on the peony seed crude oil to obtain the peony seed oil. The extraction method of the peony seed oil can lower the loss of nutritional components after oil extraction, increases the nutritive value of the peony seed oil, can shorten the production process, can lower the cost and is high in extraction rate by synchronously performing extraction, deacidifying and degreasing of the peony seed oil and has very good popularization and application prospect.

Description

technical field [0001] The invention belongs to the technical field of peony deep processing, and in particular relates to a method for extracting peony seed oil. Background technique [0002] Peony seed oil, also known as peony oil, is a woody nut vegetable oil extracted from peony seeds. It is unique to China. It is rich in nutrients and unique, and has medical and health care functions. It is called "the best oil in the world" by relevant experts , "It is a treasure in vegetable oil, and it is also a unique health care edible oil in China. Peony seed oil is the most suitable oil for human nutrition among the oils found so far. It has the highest total nutritional value and the most reasonable composition structure of all edible oils. [0003] At present, pressing method and organic solvent extraction method are mostly used to prepare peony seed oil. These methods are not only costly, but also easily cause protein denaturation and reduce nutritional value. Therefore, it ...
