CITRAL, which appears to be more effective than OEO, has
already been successfully used for the inhibition of yeast growth
and lactic acid bacteria in fruit-based salads (Belletti, Lanciotti,
Patrignani, & Gardini, 2008). CITRAL can also be used to prolong
the shelf-life of “four season salads”. In this study with real foodstuffs,
essential oil produced lower effects than in another test
carried out “in vitro” in our laboratory (Muriel-Galet et al., 2012),
which can be attributed to partial sorption of the agent in the food,
with a subsequent reduction in concentration in the vapour phase.
A reduction in the antimicrobial activity of essential oils due to the
nature of the food matrix has been documented (Belletti et al.,
