Controlled atmosphere storage of wild strawberry fruit (Fragaria vesca L.).
Controlled atmosphere storage technology to extend the shelf life of "Reina de los Valles" wild strawberry fruit (Fragaria vesca L.) was studied. Fruits were stored at 3 degrees C for three weeks in different atmosphere compositions: 0.05% CO2/21% O2 (air), 3% CO2/18% O2, 6% CO2/15% O2, 10% CO2/11% O2, and 15% CO2/6% O2. The effect of gas composition on soluble solids content, titrable acidity, pH, off-flavor, aroma volatiles, and consumer preference was monitored. The result showed that the 10% CO2/11% O2 combination can efficiently prolong the shelf life of wild strawberries by maintaining the quality parameters within acceptable values, through inhibiting the development of Botrytis cinerea, without significantly modifying consumer acceptance.
