Technical Field

The invention relates to a vegetable raw material rich in linoleic acid grease and an extraction method, in particular to a method for extracting the linoleic acid grease by taking euscaphis konishii hayata seeds as a raw material and adopting a traditional solvent to reflux.

Background

Linoleic acid, an unsaturated fatty acid, is one of the important components of vegetable oils, an essential fatty acid in human and animal nutrition. The linoleic acid has wide application, and the sodium salt or the potassium salt of the linoleic acid is one of the components of the soap and can be used as a surfactant such as an emulsifier; the aluminum salt can be used for treating hyperlipidemia, arteriosclerosis and other diseases in medicine, and can be used for preparing paint, coating and the like. The linoleic acid is obtained from plants mostly, but the content of the linoleic acid is greatly different from that of different vegetable oils, which is greatly related to the preparation process and related parameters thereof. Researches have found that related products of linoleic acid have various preparation processes, but the existing processes are rarely explored aiming at the special chemical properties of the linoleic acid, such as easy oxidation, easy decomposition by distillation, easy polymerization at high temperature, unstable acid and alkali and the like in the traditional solvent extraction method.

Among vegetable oils rich in linoleic acid, safflower seed oil has the largest linoleic acid content, accounting for 70-83% of the total fatty acids, and walnut oil, cottonseed oil (with a linoleic acid content of 44.9-55%), sunflower seed oil, sesame oil, etc., accounting for about 40-60% of the total fatty acids, with a lower linoleic acid content in animal oils. Therefore, the subject group is always dedicated to find new plant resources rich in linoleic acid, and hopes to find new plant resources rich in plant resources, high in oil content and particularly high in linoleic acid content; meanwhile, the method is simple in process, low in cost and high in linoleic acid content.

According to Chinese and local plant record, the oil content of fructus Bruceae of Euscaphis japonica of Staphyleaceae is 25-38%, and seed oil can be used for preparing soap; the method is mainly characterized in that seeds of euscaphis konishii hayata with the seed coat and the crust removed are mainly used for extracting grease; because the seed shells are smooth and hard, the seeds are very small, and the seeds are generally broken when being broken, the seeds are very difficult to break and separate, the production labor is large, the cost is high, the production of the euscaphis japonica oil cannot be actually operated, and the euscaphis japonica oil has not yet come into the market. Meanwhile, the original records only show that the seed oil can be used for preparing soap, so that no one can study the components or the compositions of the seed oil before, no more description is provided for the application, and the intensive research and development of the new application of the comprehensive utilization of the seed oil are greatly needed.
