Embodiment 1

[0021] The preparation method of peony seed oil comprises the following steps: shelling, screening, sorting, roasting, pressing, filtering, alkali refining and hydration, decolorizing, filtering and deodorizing the dried and selected peony seeds to obtain refined peony seeds seed oil. The important process parameters in the preparation steps are: the moisture content of the peony seeds sent to the peeling machine for shelling is 16%, 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 sieve is 14 m / s; the roasting temperature is 90°C, and the frying time is 50 minutes; the working pressure of the filter is 6 MPa when filtering crude crude oil; add NaOH solution with a concentration of 10% Alkali refining, then adding water at 60°C for degumming, the amount of water added is 5% of the weight of the crude oil, while stirring continuously at a speed of 50 rpm for 3 minutes, and sedime...

Embodiment 2

[0023] The preparation method of peony seed oil, step is with embodiment 1. The important process parameters in its preparation steps are as follows: the peony seeds that are sent into the peeling machine have a moisture content of 15%. 0.3cm square grid, the wind speed at the screen is 13 m / s; the roasting temperature is 100°C, and the frying time is 60 minutes; the working pressure of the filter is 4MPa when filtering crude crude oil; add NaOH with a concentration of 11% Solution alkali refining, then add 70°C water for degumming, the amount of water added is 6% of the weight of the crude oil, while stirring continuously at a speed of 60 rpm for 3 minutes, and sedimentation for 5 hours; using activated clay for decolorization, the dosage is 5% of the oil weight, the temperature is controlled at 100°C, and the active clay is put into it while continuously stirring at a speed of 50 rpm for 30 minutes; the decolorized crude oil is pumped into the slag discharge filter for 40 mi...

Embodiment 3

[0025] The preparation method of peony seed oil, step is with embodiment 1. The important process parameters in the preparation steps are: the moisture content of the peony seeds sent to the sheller for shelling is 8%, 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 15 m / s;

[0026] The frying temperature is 90°C, and the frying time is 40 minutes; the working pressure of the filter is 5MPa when filtering crude oil; add 10% NaOH solution for alkali refining, then add 80°C water for degumming, the amount of water added is 7% of the weight of crude oil, while continuously stirring at a speed of 50 rpm for 3 minutes, and sedimentation for 5 hours; using active white

[0027] Soil decolorization, the dosage is 5% of the oil weight, the temperature is controlled at 100°C, and the activated clay is put into it while stirring continuously at a speed of 50 rpm for 30 minutes...

Abstract

The invention provides a preparation method of peony seed oil. The oil content in the peony seed oil is above 22%, wherein the content of unsaturated fatty acid can be as high as 90%, and the content of alpha-linolenic acid can be as high as 42.3%, so that the peony seed oil has great development value. The preparation method comprises the following steps: husking, screening, sorting, roasting, stir-frying, pressing, filtering, alkali-refining, hydrating, decoloring, filtering and deodorizing dried and picked peony seeds for getting the peony seed oil, thereby realizing the industrial production of the peony seed oil; and the peony seed oil can be effectively extracted by adopting the steps, and the oil yield of the peony seed oil can be as high as 26-27%.

Description

technical field [0001] The invention relates to oil preparation from oil-containing materials, in particular to a method for preparing 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 of extracting supercritical CO2 extraction to extract and collect oil to obtain peony seed oil. The extraction rate of the peony see...
