Strawberry fruits (cv. E vie2) 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 O 2 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. Practical Applications The modified atmosphere packaging ( MAP ) combined with high temperature could result in changes in quality and affect the main volatile compounds of strawberries along the storage. In this work, we evaluated two wrapping films (a polypropylene and a biobased film from starch corn) to store strawberries under different MAP conditions (active and passive) at high temperatures. Treatments able to maintain the most important qualitative traits and the aroma composition of fruits near to the harvest (0 day) could be considered when the cold conditions are not guaranteed in a distribution chain.
