Embodiment 1

[0014] Step 1: Optimizing the pomegranate seeds, washing them with water to remove impurities and soil, drying the washed pomegranate seeds and putting them into the drying equipment, ensuring that the drying temperature in the drying room is between 56°C and the drying time is After 6 hours, when the water content is less than 7%, put it into a crushing equipment to crush and sieve to obtain 29-mesh pomegranate seed fragments, which are set aside;

[0015] Put 370kg of pomegranate seed fragments into the extraction kettle and start the extraction. The extraction temperature is 52°C, the extraction pressure is 26Mpa, and the extraction time is 130min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the pomegranate seed fragments. Set the pressure in the extractor to 18Mpa and the temperatu...

Embodiment 2

[0019] Step 1: Optimizing the pomegranate seeds, washing them with water to remove impurities and soil, draining the washed pomegranate seeds and putting them into the drying equipment to ensure that the drying temperature in the drying room is between 46°C and the drying time is After 5 hours, when the water content is less than 7%, put it into a crushing equipment to crush and sieve to obtain 33-mesh pomegranate seed fragments, which are set aside;

[0020] Put 330kg of pomegranate seed fragments into the extraction kettle and start the extraction. The extraction temperature is 44°C, the extraction pressure is 27Mpa, and the extraction time is 144min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the pomegranate seed fragments. Set the pressure in the extractor to 13Mpa and the tempera...

Abstract

The invention discloses a supercritical extraction method of pomegranate seed oil. The method comprises the steps of washing, drying, grinding, supercritical extraction, and molecular distillation, and has the advantages that the operation temperature is low, the heating time is short, the grease oxidation and rancidity caused by high temperature can be avoided, moreover, the separation degree and product yield are high, the acid value of grease is reduced by the molecular distillation; high efficient extraction and separation can be achieved, the essential oil does not contain any impurity, the purity of the extraction product is high, the operation and technology are simple, the extraction time is short, the cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an extraction method of pomegranate seed oil, in particular to a supercritical extraction method of pomegranate seed oil. Background technique [0002] Pomegranate seed oil is the only polyunsaturated conjugated fatty acid of plant origin, its main component is punicic acid, and its content can reach 70-80%. Because the structure of punicic acid is closest to conjugated linoleic acid (CLA), it is called "super conjugated linoleic acid", and its functionality exceeds that of conjugated linoleic acid in the general sense. Pomegranate has extremely high edible and medicinal value. According to research, pomegranate fruit contains 10%-15% sugar, vitamins contain more than 10mg per hectogram edible part, and fat and protein content are 0.5% and soluble fruit acid 0.5%. %, in addition to phosphorus, potassium, calcium, magnesium, zinc and other elements necessary for the human body. Pomegranate seeds account for about 12% of the to...
