Abstract:		"Volatile organic compounds, quality and sensory attributes of sweet cherry cv 'Ferrovia', cold packaged in Air or in different modified atmospheres (Low-O(2)?ª+=?ª+1% O(2)/0.03% CO(2); High-CO(2)?ª+=?ª+16% O(2)/20% CO(2); Mix?ª+=?ª+1% O(2)/20% CO(2)), were monitored until 21?ª+days of conservation. Results showed that sweet cherry cv 'Ferrovia' is sensitive to CO(2) accumulation (over 20%) in low oxygen (about 1%) modified atmosphere, as showed by the increase in respiration rate, biosynthesis of fermentative volatile metabolites, and sensory perception of off-odours. However, High-CO(2) treatment seemed to preserve quality and sensory traits, presumably due to the high initial concentration of O(2) (16%) that could limit the synthesis of ethyl esters and gamma-butyrolactone, keeping the accumulation of off-flavours below their sensory perception threshold. Finally, PLSR analysis allowed to select 1-pentanol as putative marker of sensory alteration and hexanal and 2-hexenal as possible predictors of freshness for 'Ferrovia' sweet cherries"
