The inhibitory effect of mustard essential oil (EO) in vapor phase against Aspergillus niger was evaluated in vitro and in vivo (in tomatoes). Mold response in tomatoes exposed for short or long periods to selected concentrations of mustard EO was also evaluated. Furthermore, a sensory evaluation was also performed among treated tomatoes and compared with nontreated ones. Minimum inhibitory concentration (MIC) for the studied EO was determined by the inverted Petri dish method. MIC for the in vitro and in vivo tests for mustard EO was of 3.08 μ L/ Lair . In vitro and in vivo results demonstrate the effectiveness of vapors of mustard EO against A. niger . The studied EO contains highly volatile organic compounds with strong inhibitory effects, even when applied for short periods, and can consequently be considered a good alternative to traditional synthetic antimicrobials without detriment of selected sensory attributes.
