Abstract

The invention discloses a sweet orange essential oil decoloring and aroma conserving method, and belongs to the technical field of spice processing. The method includes the steps of adding 6-12% of activated clay decoloring agent to sweet orange essential oil to be evenly stirred, putting the mixture into a constant-temperature device, keeping the temperature within the range of 55 DEG C to 70 DEG C in a closed mode, stirring for 20-35 min, and finally conducting suction filtration. The maximum decoloring rate can reach 84.53%, oxy-terpenes aroma active substances in the essential oil can be effectively kept, and finally the decolored sweet orange essential oil clear, colorless and rich in fragrance is obtained. The influences of different decoloring agents and different processing conditions on the decoloring effect of the sweet orange essential oil are determined, the optimal decoloring conditions are determined, and the high-quality decolored sweet orange essential oil can be obtained through the method.
