Problems solved by technology

This is related to the hard peony seed coat and the difficulty of crushing. The difficulty of crushing will affect the degree of crushing and prolong the crushing time. The larger particle size of the crushed material will reduce the extraction efficiency. The prolonging of the crushing time may cause more unsaturated fatty acids in the It is destroyed during the crushing process, thereby reducing the quality and oil yield of peony seed oil

Embodiment 1

[0027] The invention provides a kind of preparation method of peony seed oil, comprises the following steps:

[0028] S1. Soak peony seeds after shelling and removing impurities in water at 16°C for 9 hours, take out and drain the water, store at low temperature and crush to 140 mesh to obtain peony seed powder. The method of low temperature preservation is to store at minus 47°C 4.8 hours;

[0029] S2. Dry the peony seed powder obtained in S1 at 44°C at a low temperature. When the water content reaches 8.9%, soak it in absolute ethanol that is 1 times the weight of the peony seed powder for 4.6 hours, and perform supercritical carbon dioxide extraction. In carbon dioxide extraction, the extraction pressure is 27Mpa, the extraction temperature is 42°C, the extraction time is 71 minutes, and the carbon dioxide flow rate is 16.8L / h; the supercritical carbon dioxide extraction instrument used has two separation tanks, and the pressure of the first separation tank is 8.9Mpa, the ...

Abstract

The invention discloses a preparation method of peony seed oil. The method comprises the following steps: shelling peony seeds and removing impurities, then soaking the shelled peony seeds and storingat the low temperature, and crushing to 130-150 meshes to obtain peony seed powder; drying the peony seed powder at the low temperature; when the water content reaches 8-10%, soaking in anhydrous ethanol for 4-5h, and carrying out supercritical CO2 extraction to obtain peony seed crude oil; heating the peony seed crude oil up to 50-60 DEG C, adding a sodium hydroxide solution, stirring for 15-20min, then heating up to 70-80 DEG C, adding aluminum oxide, stirring for 20-30min, carrying out heat preservation and standing for 8-10h, separating to remove water layer and precipitate to obtain deacidified oil; decoloring and deodorizing the deacidified oil to obtain the peony seed oil. The preparation method of the peony seed oil is high in oil yield, and the obtained peony seed oil is high incontent of unsaturated fatty acid.

Description

technical field [0001] The invention relates to the field of peony seed processing, in particular to a preparation method of peony seed oil. Background technique [0002] Peony seeds are the crystallization of the essence of peony plants. In addition to inheriting all the characteristics of peony itself, it has its own unique medicinal and nutritional components. Peony seeds are nuts protected by double shells and seed shells. "Gene. [0003] 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. It is rich in polyunsaturated fatty acids, and its nutritional value far exceeds that of the so-called "Oil of human health" olive oil. The content of linolenic acid is more than 200 times that of olive oil, and many indicators are also higher than other oils, and it is not easy to oxidize and deposit on human blood vessel walls, coronary a...
