Corona discharge air plasma (CDAP) is a nonthermal decontamination technology which is generating antimicrobial agents such as photons, electrons, positively and negatively charged ions, atoms, and free radicals. We investigated the effect of a corona discharge under atmospheric pressure on the sterilization of postharvest fungal pathogens on onion. The main antimicrobial reactive substance generated by CDAP was O3. The active species such as nitric oxide (NO) and nitric dioxide (NO2) were nearly detected in this experiment. CDAP treatment revealed different isolation frequencies depending on postharvest pathogens from diseased onions, showing less isolation frequency of Fusarium spp. and Alternaria sp. than that of Botrytis spp. when compared with untreatment onions during 10-month cold storage. CDAP treatment at 2∼2.6 ppm of O3 slightly stimulated the mycelial growth of Alternaria sp., while the treatment at 20∼24 ppm of O3 gradually inhibited mycelial growth by treatment time. However, Botrytis sp. showed different patterns of mycelial growth with CDAP treatment. Less than 4 hours’ treatment of CDAP slightly inhibited the mycelial growth of Botrytis sp., while 8 hours’ treatment of CDAP slightly stimulated the mycelial growth of Botrytis sp. not depending on the concentration of O3. The inhibitory effect of CDAP on the conidial germination of Alternaria sp. and Botrytis sp. was examined with treatment time and intensity of CDAP. The conidial germination of Alternaria sp. treated with CDAP at the concentration of 13.7∼14.4 ppm of O3 was strongly inhibited by time, showing y = 2.66x2 − 85.139x + 4.88 and R2 = 0.98. When the conidia of Alternaria sp. were exposed for 2 hours with varying plasma O3 concentration, the conidial germination was strongly inhibited as the concentration of O3 increases, showing y = −0.09x2 + 6.905x − 0.764 and R2 = 0.95. The conidia of Botrytis sp. also showed similar patterns to CDAP. The inhibitory effect of CDAP on the germination of postharvest pathogens depends on treatment time and O3 concentration.

Edible chitosan coating on the surface of ready-to-eat (RTE) bovine meatballs was evaluated for its effect on their shelf life and the control of Listeria monocytogenes at 5 °C. L. monocytogenes was inoculated onto the surface of RTE bovine meatballs with and without edible chitosan coating. The samples were stored at 5 °C. Total aerobic viable count (TVC) and the bacterial counts of L. monocytogenes, lactic acid bacteria and Enterobacteriaceae were determined on days 0,1,7,14,21 and 28. The sensory characteristics were also evaluated at the same time spots by semi trained panelists. The results of the microbiological analysis depicted that the use of edible chitosan membranes reduced all of the microbial populations that were enumerated, and retarded their growth leading to the conclusion that they can prolong the shelf life of these products by 14 days. Moreover, the population of the inoculated L. monocytogenes was about 2 log CFU/g lower in the meatballs coated with chitosan, indicating an inhibitory effect of chitosan in the growth of L. monocytogenes. The sensory analysis showed that the samples coated with chitosan were satisfactorily accepted by the panelists even at day 28, in contrast to the samples without chitosan (control samples) which were unacceptable at day 14. These results indicate that edible chitosan coatings represent a potential agent in controlling L. monocytogenes on the surface of RTE meatballs as well as other RTE meat products, prolonging their shelf life without affecting their sensory characteristics.
