“…Recently, our group also demonstrated the inactivation of an enzyme in tomato extract using the same plasma source [14]. We have not found significant changes in the food packaging material following NTP treatments to declare hazards from this process [15,16]. Besides microbiological concerns, pesticides residues in strawberries also pose a serious health risk, for they are often consumed without washing or are minimally processed.…”

Keywords: nonthermal plasma, dielectric barrier discharge, pesticide, GC-MS/MS AbstractIn-package nonthermal plasma (NTP) technology is a novel technology for the decontamination of foods and biological materials. This study presents the first report on the potential of the technology for the degradation of pesticide residues. A cocktail of pesticides, namely Azoxystrobin, Cyprodinil, Fludioxonil and Pyriproxyfen was tested on strawberries. The concentrations of these pesticides were monitored in priori and post-plasma treatment using GC-MS/MS. An applied voltage and time dependent degradation of the pesticides was observed for treatment voltages of 60, 70 and 80 kV and treatment durations ranging from 1 to 5 min, followed by 24 h in-pack storage. The electrical characterisation revealed the operation of the discharge in a stable filamentary regime. The discharge was found to generate reactive oxygen and excited nitrogen species as observed by optical emission spectroscopy.

“…Although it is a promising technology for different fields in the food production, presently, the only commercial application of ACP technology for the food industries is limited to polymer processing used for food packaging applications (Pankaj et al, 2014;). However, a fundamental understanding of the interactions between plasma and biomacromolecules has remained under researched.…”

“…A summary of the important studies reporting the degradation of pesticides using NTP is provided in Table 3. Clearly, the process variables for optimisation of NTP effects vary with the type of set-up employed and include power applied, operating frequency, electrode contact area, discharge gap, distance from plasma source, treatment time, discharge gas type, gas pressure and gas flow rate, besides the packaging material used (Kelly & Turner, 2014;Pankaj, Bueno-Ferrer, Misra, Milosavljević, et al, 2014;Pankaj, Bueno-Ferrer, Misra, O'Neill, et al, 2014).…”
