Embodiment 1

[0026] (1) Seed collection: pick the purple-spotted peony follicles that have just cracked and the skin has turned yellow in mid-to-late August in Zhongchuan Peony Garden, Gansu, and put them in a cool and ventilated place indoors to dry naturally, turn them every two days, and leave them for 6 days to wait for their fruits All of them are cracked, and they are beaten with wooden sticks until all the seeds fall off, so as to obtain 113 kg of peony seeds.

[0027] (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.

[0028] (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 8r / m...

Embodiment 2

[0035] (1) Seed collection: Pick the purple-spotted peony follicles that have just cracked and the skin has turned yellow in mid-to-late August in Zhongchuan Peony Garden, Gansu, and put them in a cool and ventilated place indoors to dry naturally, turn them every three days, and leave them for 6 days to wait for their fruits All of them are cracked, and they are beaten with wooden sticks until all the seeds fall off, so as to obtain 113 kg of peony seeds.

[0036] (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.

[0037] (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 10...

Embodiment 3

[0041] (1) Seed collection: pick the purple-spotted peony follicles that have just cracked and the skin has turned yellow in late August in Zhongchuan Peony Garden, Gansu, and put them in a cool and ventilated place indoors to dry naturally, turn them every two or three days, and let them stand for 8 days to wait for the fruit Crack all the seeds and beat them with wooden sticks until all the seeds fall off to obtain 55 kg of 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, and the peony seed oil is squeezed out under pressure, and the rotation speed of the screw shaft is 8-1...

Abstract

The invention relates to a method for extracting and refining paeonia rockii seed oil. The method comprises the following steps: collecting seeds, unshelling, baking and frying, carrying out screw press, filtering, deacidifying, degumming, drying, decoloring, deodorizing in vacuum, adding an antioxidant and filling. After solid impurities and residues obtained by the screw press are broken up, ethylacetate is added, then refluxing extraction is carried out, and a solvent is recovered so as to obtain the paeonia rockii seed oil for cosmetics. A two-step method is used for extracting the paeonia rockii seed oil, wherein in the first step: primary pressed oil used for eating is obtained by physical pressing, and the produced paeonia rockii seed oil has higher oil recovery rate and no residual solvents and can be securely eaten; in the second step, the ethyl acetate is adopted for extraction, and ingredients for antioxidation, inflammation resistance, sun block, and the like in the paeonia rockii seed oil can be extracted and used for producing the cosmetics. The invention not only improves the oil recovery rate of paeonia rockii seeds, but also ensures that the effective ingredients in the paeonia rockii seeds are sufficiently utilized.

Description

technical field [0001] The invention relates to the technical field of peony deep processing, in particular to the high-efficiency extraction and utilization technology of peony seed oil, in particular to a method for extracting and refining the peony seed oil. Background technique [0002] Gansu is an important birthplace of Chinese peony. Gansu purple spot peony is the second largest variety group of Chinese peony. It is widely cultivated in various parts of Gansu for its characteristics of cold resistance and drought tolerance, tall plants, and strong knot strength. For a long time, the peonies cultivated in various places are mainly for ornamental purposes and sales of seedlings. However, the development and utilization of deep-processed products of peony has lagged behind seriously, the added value of production is very low, and no industrial chain has been formed. In particular, only a small amount of peony seeds are used for breeding. A large number of seeds fall in v...
