Embodiment 1

[0020] The preparation method of the peony seed oil comprises the following steps: peeling, screening, sorting, pressing, filtering, alkali refining and hydration, decolorizing, filtering and deodorizing the dried and selected peony seeds to obtain the refined peony seed oil. The important process parameters in its preparation steps are: the moisture content of the peony seeds sent into the peeling machine for shelling is 16%, the upper sieve is a square mesh with a side length of 0.9 cm during screening, and the lower sieve is a side length of 0.9 cm. 0.3cm square grid, the wind speed at the screen is 15 m / s; the working pressure of the filter is 6MPa when filtering crude oil; add 10% NaOH solution for alkali refining, then add water at 60°C for degumming, adding water The amount is 5% of the weight of the oil, and at the same time, it is continuously stirred at a speed of 50 rpm for 3 minutes, and precipitated for 5 hours; the amount is 5% of the weight of the oil, and the te...

[0022] The preparation method of the peony seed oil comprises the following steps: peeling, screening, sorting, pressing, filtering, alkali refining and hydration, decolorizing, filtering and deodorizing the dried and selected peony seeds to obtain the refined peony seed oil. The important process parameters in the preparation steps are: the moisture content of the peony seeds sent to the sheller for shelling is 12%, the upper screen is a square grid with a side length of 1 cm, and the lower screen is a side length of 0.4 cm. cm square grid, the wind speed at the screen is 14 m / s; the working pressure of the filter is 4MPa when filtering crude oil; add NaOH solution with a concentration of 11% for alkali refining, and then add water at 70°C for degumming, adding water The amount is 6% of the weight of the oil, and at the same time, it is continuously stirred at a speed of 60 rpm for 3 minutes, and precipitated for 5 hours; the amount is 5% of the weight of the oil, and the temp...

Embodiment 3

[0024] The preparation method of the peony seed oil comprises the following steps: peeling, screening, sorting, pressing, filtering, alkali refining and hydration, decolorizing, filtering and deodorizing the dried and selected peony seeds to obtain the refined peony seed oil. The important process parameters in its preparation steps are: the peony seeds sent into the peeling machine have a moisture content of 8%, the upper sieve is a square mesh with a side length of 0.9 cm, and the lower sieve is a side length of 0.9 cm. 0.3cm square mesh, the wind speed at the screen is 13 m / s; the working pressure of the filter is 5MPa when filtering crude crude oil; adding 10% NaOH solution for alkali refining, and then adding 60-80°C water for degumming, The amount of water added is 7% of the weight of the crude oil, and at the same time, it is continuously stirred at a speed of 50 rpm for 3 minutes, and precipitated for 5 hours; the amount of water is 5% of the weight of the oil, and the ...

Abstract

The invention provides a cold-pressing method of peony seed oil. The peony seed oil has high oil contest of over 22%, wherein the content of unsaturated fatty acid content is as high as 90%, the content of alpha-linolenic acid is as high as 42.3%, and therefore, the peony seed oil has high development value. The cold-pressing method comprises the following steps of: drying peony seeds in the sun, selecting high-quantity peony seeds, shelling, sieving, sorting, pressing, filtering, alkali refining for hydrating, decoloring, filtering and deodorizing to finally obtain the peony seed oil. The industrialized production of the peony seed oil is realized with the method; and by adopting the processing steps, the peony seed oil can be extracted effectively with high yield up to 26-27%.

Description

technical field [0001] The invention relates to a preparation method of peony seed oil, in particular to a cold pressing preparation method of peony seed oil. Background technique [0002] my country is the largest peony planting country in the world, and the annual output of peony seeds ranks first in the world. The oil content of peony seeds is as high as 22%. Peony seed oil contains a large amount of linolenic acid and linoleic acid needed by the human body. Among them, the content of unsaturated fatty acids is as high as 90%, and the content of linolenic acid is as high as 42.3%. development value. However, peony seeds have not been utilized so far, and there are few reports about the composition, processing characteristics and preparation of peony seed oil at home and abroad. [0003] Chinese invention patent CN200810246716.4 discloses a method for extracting supercritical CO 2 The method of extraction extracts and collects oil, and obtains peony seed oil. The extra...
