Treatment method for concrete and absolute type natural extractive suitable for electronic cigarette

The invention provides a treatment method for concrete and absolute type natural extractive suitable for an electronic cigarette. According to the method, the frequently-used concrete, absolute type edible spice and absolute type spice for the cigarette are diluted through propylene glycol or glycerol (the mass ratio is 1:1-20:1), the molecular distillation is performed, and therefore light components are obtained and are products after treating the concrete and absolute type natural extractive suitable for the electronic cigarette. The treatment process is simple, treated natural extractive is dilution of the propylene glycol or glycerol and can be directly used for producing electronic cigarette liquid. Through treatment, high-boiling-point substances and a waxy component in the spice can be removed, the defect that high-boiling-point spice easily generates a charring smell is overcome, the extractive can be completely dissolved in the electronic cigarette liquid so that the electronic cigarette liquid can be clear and bright, the fragrance permeability is better, and the method can enlarge the selection range of the spice for the electronic cigarette.
