Embodiment 1

[0032] (1) Selected and air-dried seeds: Pick the purple-spotted peony fruit that has just cracked and the peel has turned yellow, and put it in a cool and ventilated place indoors to dry naturally, turn it every two days, leave it for 6 days until all the fruits are cracked, and beat it with a wooden stick All the seeds fall off, and 400 kg of peony seeds are obtained.

[0033] (2) Hulling and roasting: take peony seeds, mechanically peel and remove impurities. Put the peeled peony seeds into a pan, stir-fry slowly on low heat, turn frequently, control the temperature of the peony seeds at 120°C, and fry until the peony seeds are crushed and turn yellow.

[0034] (3) Hydraulic pressing and filtering: the roasted peony seed kernels are cooled to 60°C and evenly and continuously sent to the hydraulic press for pressing, and the squeezed crude oil is filtered with an oil filter, and the residue is left to be used to obtain the first pressed peony seed hair Oil 75kg.

Embodiment 2

[0041] (1) Select and dry the seeds: Pick the purple-spotted peony follicles that have just cracked and the peel has turned yellow, and put them in a cool and ventilated place indoors to dry naturally, turn them every two days, and leave them for 6 days until the fruits are all cracked. Beat the sticks until all the seeds fall off to obtain peony seeds.

[0042] (2) Hulling and roasting: take peony seeds, mechanically peel and remove impurities. Put the peeled peony seeds into a pan, stir-fry slowly on low heat, turn frequently, control the temperature of the peony seeds at 120°C, and fry until the peony seeds are crushed and turn yellow.

[0043] (3) Screw pressing and filtering: the roasted peony kernels are cooled to 60°C and evenly and continuously sent to the screw press for pressing. The peony seed oil is squeezed out under pressure. The speed of the screw shaft is 10r / min. The crude oil is filtered by an oil filter to obtain the first-pressed peony seed crude oil, and ...

Embodiment 3

[0047] (1) Selected and dried seeds: Pick the purple-spotted peony follicles that have just cracked and the skin has turned yellow, and put them in a cool and ventilated place indoors to dry naturally, turn them every two days, and place them for 8 days until all the fruits are cracked. Beat with a stick until all the seeds fall off to obtain 1600 kg of peony seeds.

[0048] (2) Hulling and roasting: take peony seeds, mechanically peel and remove impurities. Put the peeled peony seeds into a pan, stir-fry slowly over low heat, turn frequently, control the temperature of the peony seeds at 120°C, and stir-fry until the peony seeds are crushed and turn yellow.

[0049](3) Hydraulic pressing and filtering: the roasted peony seed kernels are cooled to 60°C and evenly and continuously sent to a hydraulic press for pressing. The peony seed oil is squeezed out under pressure, and the squeezed crude oil is filtered by an oil filter , wherein the residue is set aside to obtain the fir...

Abstract

The invention provides a preparation method for a selenium-rich peony seed essential oil, and relates to the technical field of edible oil. The preparation method comprises the following steps: (1) carrying out fine selection and air drying on seeds, (2) carrying out shelling and roasting-frying, 3) carrying out hydraulic pressing and filtration, (4) carrying out deacidification, (5) carrying out degumming, (6) carrying out drying and decolorization, (7) carrying out vacuum deordorization, and (8) adding an antioxidant to obtain the peony seed essential oil, wherein the standby solid impurity residue in the step (3) is broken up, and is added with acetic ether, then the resulting material is subjected to reflux extraction, and reduced pressure solvent recovery is performed to obtain the peony seed essential oil for cosmetics. The preparation method of the present invention has the following beneficial effects that: the two-step method is adopted to extract the peony seed oil, physical pressing is adopted in the first step, and the produced peony seed oil has characteristics of high oil yield, no solvent residue and edibility; the acetic ether extraction is adopted in the second step, such that the anti-oxidation component, the anti-inflammatory component, the sunscreen component and other components in the peony seed oil can be completely extracted to be used for cosmetic production so as to effectively improve oil yield of the peony seeds and completely utilize active components in the peony seeds.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, and further relates to the production technology of peony seed oil, especially the preparation method of peony seed essential oil, especially selenium-enriched peony seed essential oil. Background technique [0002] Peony is a unique woody and precious flower in my country. It is known as "National Beauty and Heavenly Fragrance" and "King of Flowers". It has long been regarded as a symbol of wealth, auspiciousness and prosperity. Peony not only has ornamental value, but also has high medicinal value.
