Problems solved by technology

[0004] At present, the types of main products on the market are powdery rosemary extract and oily liquid rosemary extract, but powdery rosemary extract has low solubility in edible oil, dissolves slowly, and needs high temperature to accelerate dissolution, and There are still insoluble matter, which needs to be treated by filtration process, which will reduce the utilization rate, affect the use effect of the product, and limit the scope of application
The oily liquid rosemary extract extracted by supercritical carbon dioxide has high production cost, single product and darker color
There is also a Chinese invention patent "Comprehensive removal of rosemary and method for preparing fat-soluble instant antioxidants" (application number: 201110021081.X, publication number: 102604640A) is dissolved in a low boiling point solvent, transferred to edible oil, concentrated The oil-soluble instant rosemary extract is recovered, but this method is prone to precipitation, and it needs to be left for 1 day to 1 week to remove the precipitation to obtain the product. The storage time is long and repeated treatment is required
