“…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.

“…It may be noted that the thickness of the packaging film employed in this study is higher than those used in actual practice. However, the high barrier nature of the packaging film allows retention of the active plasma species without leakage and also serves as a stable dielectric material preventing a transition of the discharge to arc regime (13). Studies in our laboratory have revealed that nature and thickness of packaging material plays an important role in preventing sparks.…”

“…There are several types of surface modification techniques used in the packaging industry for adhesion improvement of coatings, among others; corona treatment, chemical treatment or priming (Robertson., 2014) and plasma treatment. Cold plasma induces several chemical and physical processes within the plasma volume and on the plasma-polymer interface, which modify surface properties (Pankaj et al, 2014).…”

Surface attachment of active antimicrobial coatings onto conventional plastic-based laminates and performance assessment of these materials on the storage life of vacuum packaged beef sub-primals

'Surface attachment of active antimicrobial coatings onto conventional plastic-based laminates and performance assessment of these materials on the storage life of vacuum packaged beef sub-primals ', Food Microbiology, 62, Abstract Two antimicrobial coatings, namely Sodium octanoate and Auranta FV (a commercial antimicrobial composed of bioflavonoids, citric, malic, lactic, and caprylic acids) were used. These two antimicrobials were surface coated onto the inner polyethylene layer of cold plasma treated polyamide films using beef gelatin as a carrier and coating polymer. This packaging material was then used to vacuum pack beef sub-primal cuts and stored at 4°C. A control was prepared using the non-coated commercial laminate and the same vacuum packaged sub-primal beef cuts. During storage, microbial and quality assessments were carried out. Sodium octanoate treated packages significantly (p<0.05) reduced microbial counts for all bacteria tested with an increase of 7 and 14 days, respectively compared to control samples. No significant effect on pH was observed with any treatment. The results suggested that these food grade antimicrobials have the potential to be used in antimicrobial active packaging applications for beef products.
