| titleOfInvention | Method for extracting limonene from fruit skin of citrus |
| abstract | The invention provides a method for extracting from fruit skin of citrus, which comprises the following steps: adding fruit skin of citrus into a reflux extraction kettle, adding water in an amount which is 5 to 15 times the mass of the fruit skin and an organic solvent in an amount which is 2 to 10 times the mass of fruit skin, heating and stirring till the materials are mixed uniformly; performing ultrasonic wave assisted solvent extraction at 30 to 80 DEG C for 10 to 30 minutes continuously; adding active carbon for decolorization, stirring for about 30 minutes and cooling to 15 to 25 DEG C; filtering and separating decolorized product to obtain filtrate and filter residue, and subjecting the filtrate to phase splitting to obtain an organic phase A' and a water phase B; extracting the water phase B by using the organic solvent in an amount which is 0.2 to 0.5 percent based on the mass of the added fruit skin to obtain an organic phase A' and a water phase B'; and mixing the organic phase A and the organic phase A', performing normal pressure distillation separation at 40 to 100 DEG C to obtain limonene and the solvent, and collecting the limonene. The method has the advantages of high limonene extraction rate, simple process, suitability for industrial production and the like. |
