The invention aims to provide a method for improving euryops pectinatus oil aroma quality and application thereof. The method includes: subjecting euryops pectinatus to low temperature superfine comminution, then adding a certain amount of acid, an oxidant and enzyme and mixing the substances evenly in an aqueous solution, conducting incubation fermentation for a certain period of time under a synergistic effect, and carrying out steam distillation to extract volatile oil. The method improves the extraction rate and aroma quality of euryops pectinatus oil, the euryops pectinatus oil has composite, natural and rich aroma, besides chrysanthemum characteristic aroma, also has flower fragrance, fruit sweet aroma, slightly cool sense feel and other natural smell, the irritation is reduced, andthe aroma quality is improved.

The extraction process of plant mildew-proof preservative includes crushing lilac flower, soaking in water, distilling to obtain distillate, the first extraction of the distillate with solvent, the second extraction of the supernatant with sodium bicarbonate, the third extraction of the second supernatant with sodium bicarbonate, and volatilizing the solvent in the lower layer to obtain the plant mildew-proof preservative. The plant mildew-proof preservative has obvious and lasting inhibition on blue mold and Aspergillus niger with serious infection to cut of fruit and vegetable, has active effective period as long as 15 months, and may be used in preserve various kinds of fruits and vegetable.
