Method for extracting fatty acid in black sesame cake dregs through sub-critical carbon dioxide

Abstract

The invention discloses a method for extracting fatty acid in black sesame cake dregs through sub-critical carbon dioxide. The method includes the following steps that the black sesame cake dregs are smashed, the smashed black sesame cake dregs are screened through a 40-mesh screen, and 40-mesh powder is put in an extraction kettle for extraction, wherein the extraction time is 2 h, the extraction pressure ranges from 12 MPa to 18 MPa, the extraction temperature ranges from 25 DEG C to 35 DEG C, and the CO2 flow ranges from 40 L / h to 50 L / h. Fatty acid, extracted through sub-critical CO2, in the black sesame cake dregs has good quality, the black sesame cake dregs serve as extraction raw materials, waste can be fully utilized, and the effective utilization rate of sesame is further increased. Sub-critical CO2 serves as an environment-friendly and efficient extraction technology, no solvent residues exist, and no pollution is caused to the environment.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for extracting fatty acids in black sesame cake with subcritical carbon dioxide. Background technique [0002] Sesame cake is the product of sesame after oil extraction. It is rich in oil and protein and has high economic and medicinal value. my country produces a large amount of sesame cakes every year, most of which can only be consumed as animal feed, and a large amount of active substances contained in it, such as sesamin, unsaturated fatty acids, pigments, etc., have not been effectively utilized. At present, the research and application of sesame cake mainly focus on the protein of sesame cake, while the extraction of fatty acids in sesame cake and related research and application are less. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a method for extract...
