Evolution of selected volatiles in chitosan-coated strawberries (Fragaria x ananassa) during refrigerated storage.
J Agric Food Chem. 2009 Feb 11; 57(3):974-80.JA

Abstract

The effect of chitosan coating on the evolution of several volatile compounds relevant to the strawberry (Fragaria x ananassa cv. Camarosa) aroma profile has been investigated. Strawberries dipped in chitosan acetate solution at 1 or 1.5% (w/w) and uncoated controls were stored at 10 degrees C for 1 week. Significant differences in aroma profile between coated and uncoated samples were observed. Most importantly, the buildup of the off-flavors acetaldehyde and ethanol was largely delayed in coated berries. With regard to the effect of chitosan on ester evolution, the levels of ethyl butanoate and ethyl hexanoate, important contributors to strawberry aroma related to fruity and sweet notes, were found to be enhanced in coated fruit. Acetate esters also increased during storage but more markedly in uncoated strawberries. These results show the potential of chitosan coatings in maintaining strawberry flavor during storage, something difficult to achieve with current conservation technologies. Moreover, differences in results for different coating concentrations are reported.
