Abstract

A method for extracting peony oil from peony seeds comprises the following steps: after peony seed stock is rinsed and cleaned, water is drained off, and the drained peony seed stock is placed into a drying cabinet for drying; peony seeds are placed into a shucking machine for shucking, and peony seed kernels are screened out; the peony seed kernels are placed into a frying-pan for roasting; peony oil is extracted from the peony seeds; the drying temperature in the drying step is 60 DEG C, after drying, the water content of the peony seeds is 15 wt percent, the roasting time in the roasting step lasts is 40 to 70 min, the roasting temperature is 70 to 110 DEG C, the method for extracting peony oil from peony seeds further comprises the steps of grinding to be thick liquid, water adding, alkali refining, centrifugal separation, raw oil mixing and the like. The method has the advantages that the process is simple, the operation is convenient, the promotion is easy, resolvent residue is avoided, the manufacturing cost is reduced, and original nutritional quality of the peony oil can be further kept.

Description

technical field [0001] The invention belongs to the technical fields of oil and chemical industry, and relates to a method for extracting edible vegetable oil, in particular to a method for extracting peony oil from peony seeds. Background technique [0002] The peony is full of treasures, the flowers are big and colorful, and the root can be used as medicine (called paeonol). The peony seed oil extracted from the peony seeds is a unique woody nut oil in China. It is unique because of its rich nutrition and has medical and health care functions. Known as "the best oil in the world" by relevant experts, it is a treasure among vegetable oils. Peony seed oil contains as much as 42% linolenic acid, which is 8 to 40 times that of olive oil, walnut oil, and tea oil. Multiple functions play a decisive role in intelligence and retinal development; the content of linoleic acid in peony seed oil exceeds 28%, which has the functions of lowering blood fat, softening blood vessels, lowe...
