The effect of modified atmosphere packaging on the quality and volatile production in 'Clara Frijs' pears.

Unripe Clara Frijs pear fruits were harvested in September in Denmark and packed in Cryovac MR film prior to subsequent storage at 20 deg C for 10 days. Control fruits were packed in unsealed bags while modified atmosphere (MA) samples were packed in sealed bags with either 0 or 8 pinholes. Equilibrium atmospheres were reached after 2 days of storage with average contents of 3.1% O2 and 10.7% CO2 in the 0-hole bag and 7.2% O2 and 12.2% CO2 in the 8-hole bag. Fruits in the 0-hole bag retained colour and firmness during storage, while fruits in the 8-hole bag only retained their colour. Fruits in the 0-hole bag showed increased production of ethyl acetate and ethanol. The total volatile concentration (without ethyl acetate and ethanol) showed overall aroma production to be lower for MA-packed fruits compared with controls. The flavour and eating quality of the MA-packed fruits did not improve compared with the control during storage, and the applied MR bag is concluded not to be the optimum bag fo

r MA-packaging of Clara Frijs fruits.
