Abstract

The invention relates to a method for extracting essential oil from shaddock ped or orange peels, which is characterized in that fresh shaddock ped or orange peels are cleaned, 100 mass portions of outer skins at the utmost surface layer of the shaddock ped or the orange peels are loaded onto a built-in sieve plate of a distillation tower, water is filled in the distillation tower, the heating temperature is between 95 and 100 DEG C, the distillation time is between 50 and 60 minutes, and essential water flows from a condenser tube, is kept stand for 8 to 12 minutes, and then is separated to obtain 8 to 10 mass portions of essential oil. The method utilizes discarded shaddock ped or orange peels as raw materials, changes waste into valuables, and has the characteristics of simple and convenient process, convenient operation, and safety and reliability; and the oil yield is between 2.85 and 3.08 percent, and the produced pure natural essential oil has high medicinal value and is used to improve the quality and taste of the food, the medicine, the cosmetics, the beverage and so on.
