Impact of temperature application and concentration of commercial sanitizers on inactivation of food-plant fungal spores.

This study aimed at quantifying the impact of the concentration of four commercial sanitizers and temperature on mold spores inactivation. The sanitizers were based on the following fungicide molecules, ethanol (ARVO 21 SR), active chlorine (ARVO CLM 600), hydrogen peroxide (Nocolyse Food) and triamine (P3 Topax 960). Food plant spores were produced under a moderate water stress, 0.

Impact of the physiological state of fungal spores on their inactivation by active chlorine and hydrogen peroxide.

This study aimed at assessing the impact of the physiological state of fungal spores on inactivation by sodium hypochlorite, 0.1% and 0.2% active chlorine, and 3% hydrogen peroxide.

Impact of intraspecific variability and physiological state on Penicillium commune inactivation by 70% ethanol.

The aim of this study was to assess the impact of the physiological state and intraspecific variability on the efficacy of 70% ethanol to inactivate conidia of Penicillium commune, used as a representative species of dairy product contaminants. Four physiological states were obtained by modifying the water activity during the production of conidia (0.995 and 0.

Production and migration of patulin in Penicillium expansum molded apples during cold and ambient storage.

The ability of three Penicillium expansum isolates to produce patulin was first evaluated in YES medium after incubation at 25 °C to select a high patulin producer. Then, a spore suspension of the selected P. expansum 3.

Production and migration of ochratoxin A and citrinin in Comté cheese by an isolate of Penicillium verrucosum selected among Penicillium spp. mycotoxin producers in YES medium.

Moldy food products that are not subject to pathogenic bacterial contamination could be trimmed by consumers to remove fungal mycelium before consumption. However, prior to giving such recommendations to consumers, it is necessary to evaluate potential mycotoxin migration in these products. This study aimed at quantifying citrinin (CIT) and ochratoxin A (OTA) accumulation and migration in a French semi-hard Comté cheese after artificial inoculation with a CIT- and OTA-producing Penicillium verrucosum strain.
