The effects of washing with tap and ozone water, ultrasonic cleaning and boiling
on 16 pesticide (ten fungicides and six insecticides) residue levels in raw
strawberries were investigated at different processing times (1, 2 and 5 min). An
analysis of these pesticides was conducted using gas chromatography with
nitrogen-phosphorous and electron capture detection (GC-NPD/ECD). The processing
factor (PF) for each pesticide in each processing technique was determined.
Washing with ozonated water was demonstrated to be more effective (reduction from
36.1 to 75.1 %) than washing with tap water (reduction from 19.8 to 68.1 %).
Boiling decreased the residues of the most compounds, with reductions ranging
from 42.8 to 92.9 %. Ultrasonic cleaning lowered residues for all analysed
pesticides with removal of up to 91.2 %. The data indicated that ultrasonic
cleaning and boiling were the most effective treatments for the reduction of 16
pesticide residues in raw strawberries, resulting in a lower health risk
exposure. Calculated PFs for alpha-cypermethrin were used to perform an acute
risk assessment of dietary exposure. To investigate the relationship between the
levels of 16 pesticides in strawberry samples and their physicochemical
properties, a principal component analysis (PCA) was performed. Graphical
