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...
