Embodiment 1

[0026] The preparation method of peony seed oil comprises the following steps: crushing and screening well-selected peony seeds, drying, extracting, filtering, concentrating, deacidifying, decolorizing and deodorizing to obtain refined peony seed oil. The important process parameters in the steps are: crush the peony seed powder through a 40-mesh sieve, and then dry it in a vacuum drying oven for 15-20 minutes until the water mass content of the peony seed kernel is 10%-15%. Ultra-high pressure auxiliary solvent entrained ethanol method was used for extraction, the organic solvents used were n-hexane and ethanol, the ratio of solid to liquid was 1:15:6 (mass of peony seed powder: volume of n-hexane: volume of ethanol, g:mL:mL), and n-hexane Alkanes and ethanol are placed in a vacuum packaging bag, and then the peony seed powder is poured into a vacuum plate bag, mixed evenly, vacuum-sealed, the extraction pressure is set to 500MPa, the holding time is 20 minutes, and the temper...

Abstract

The invention belongs to the technical field of processing of edible oils and particularly discloses a preparation method of peony seed oil. According to the preparation method of the peony seed oil, peony seeds are taken as raw materials, and the preparation method is characterized by comprising the following steps: crushing the peony seeds into peony seed powder, performing drying treatment, placing into an ultra-high pressure container, performing ultra-high pressure assisted n-hexane entrainment ethanol extraction to obtain a peony seed oil extract solution, and then performing decompression concentration, centrifugal degumming, decolorization, suction filtration, distillation, vacuum pumping and cooling to obtain a product. The preparation method disclosed by the invention is simple in process flow and short in extraction time, the extraction rate of the extracted peony seed oil is up to 30-31.5%, the content of linolenic acid in the peony seed oil after refining is up to about 60% (the proportion relative to fatty acid), the product quality is good, and the preparation method is further suitable for extensive popularization and application.

Description

(1) Technical field [0001] The invention belongs to the technical field of edible oil processing, in particular to a preparation method of peony seed oil. (2) Background technology [0002] Peony has a wide planting area in my country, especially in Shandong, Henan, and Anhui, and Luoyang, Heze, and Tongling are the main ones. Peony seed oil contains a variety of active ingredients, among which the unsaturated fatty acid content is as high as 80%, and the linoleic acid content exceeds 42%, which is more than 40 times that of the current "edible oil star - olive oil". It has skin "care experts" and The title of "Vascular Guard" is based on these high nutritional values ​​and has the regional color of raw materials. In 2011, it was approved by the Ministry of Health as a national new resource food. [0003] Chinese invention patent CN103416490A discloses a technique for extracting peony seed oil by pressing. It uses hydration combined with acid degumming to degumming peony se...
