Abstract

A process for extracting oil from plant seeds features that the supercritical CO2 fluid is used to extract the oil containing conjugated unsaturated fatty acid from the seeds of pumpkin, summer squash and pomegranate at low temp lower than 50 deg.C and 40 MPa. Its advantages are no damage to conjugated unsaturated fatty acid, high output rate and no toxic by-effect.

Description

technical field

[0001] The invention relates to a method for extracting vegetable oil, in particular to a method for extracting oil containing conjugated unsaturated fatty acids from pumpkin seeds, zucchini seeds and pomegranate seeds with supercritical carbon dioxide and the oil. Background technique

[0002] Conjugated unsaturated fatty acids have many special health functions for human physiological activities, such as anti-cancer, promoting growth, lowering blood lipids, and reducing fat accumulation. However, unsaturated fatty acid oils are easily oxidized and deteriorated, especially under heat conditions, which is more prominent for conjugated unsaturated fatty acid oils. There are many kinds of natural products rich in conjugated unsaturated fatty acid oils, for example, the endosperm of seeds of pumpkin, zucchini and pomegranate is rich in conjugated unsaturated fatty acid oils. The methods of extracting oil from plant seeds include pres...
