However, linoleic acid cannot be synthesized by the human body by itself and needs to be taken from the diet, and therefore, it is very important to provide a dietary product rich in linoleic acid.
In order to increase the utilization rate of the waste such as the grape seeds, the peel dregs and the like, the technical personnel in the field try to extract the grape seed oil from the waste such as the grape seeds, the peel dregs and the like so as to increase the comprehensive utilization rate of the grape seed oil. However, the prior art mainly adopts a squeezing method, a solvent extraction method, an enzymolysis method and the like to extract the grape seed oil, and although the extracted grape seed oil contains rich antioxidant components, the following defects exist: in the process of extracting the grape seed oil by the squeezing method, not only a complicated series of processing treatment but also long-time high-temperature treatment are required, so that the oil in the grape seed oil is easy to oxidize and rancid, and the content of linoleic acid is reduced; the solvent extraction method needs a large amount of organic solvent, so that the obtained grape seed oil has certain solvent residue, and the Rong Yiren is troublesome in recovery and treatment and also has the problems of environmental pollution and the like; in the extraction process of the enzymolysis method, polyphenol substances in the grape seed oil are easy to oxidize and degrade in the enzymolysis process, so that the polyphenol content serving as a main antioxidant substance in the finally obtained product is reduced.
Therefore, the invention provides the grape seed oil and the extraction method thereof in order to simplify the extraction process and improve the content of linoleic acid and polyphenol in the grape seed oil product.
