To apply the natural ingredients of plants in the field of food preservation, the essential oil of Cinnamomum camphor peel was isolated by salt-out pretreatment and microwave-assisted hydrodistillation. Using the single-factor mixed response surface approach, the extraction yield was optimized. A total of 14.98 mL/kg DW (dry weight: DW) was the greatest essential oil yield recorded. By using GC-MS analysis, a total of 29 compounds were found in the essential oil, with methyl eugenol (12.66%) and safrole (10.36%) being the two predominant compounds. However, the essential oil had a clear inhibitory effect on Pseudocercospora psidii at a concentration of 10 mg/mL. In conclusion, Cinnamomum camphora pericarp essential oil is anticipated to be a green natural pesticide that significantly inhibits pathogenic bacteria in crops.
