Influence of Modified Atmosphere Packaging Storage on Postharvest Quality and Aroma Compounds of Strawberry Fruits in a Short Distribution Chain

Strawberry fruits (cv. Evie2) were stored at 18 ± 1C for 2 days with a biobased and a polypropylene film in a passive and an active modified atmosphere packaging (MAP), and the packages were compared with a control (perfored) film. The effect of MAP on weight loss, color, flesh fruit firmness, soluble solids content, titratable acidity and aroma volatiles was monitored. Passive and active atmosphere with the biobased film resulted in low O2 values. Fruits wrapped with the polypropylene film in the passive atmosphere were firmer than fruits stored in the other MAP condition and they exhibited the highest value of luminosity. Strawberries stored under active MAP condition with the biobased film showed the highest ester concentration (880.87 μg/kg) and ethyl was the dominant fraction. Considering the main qualitative traits and the aroma compounds measured, the perfored film was the only film that can be suggested to be used at 18 ± 1C.
