Abstract
Abstract Low O 2 (2.0%, 1.0%, or 0.5%) or elevated CO 2 (10%, 15%, or 20%) concentrations and their combinations reduced respiration and ethylene production rates of ‘Selva’ strawberries ( Fragaria × ananassa Duch.) stored at 2C. After transfer from the various controlled atmospheres (CA) to air, respiration and ethylene production rates increased, but were still significantly lower than those of the fruits kept continuously in air. Atmospheres of 1.0% O 2 + 15% CO 2 and 0.5% O 2 + 20% CO 2 led to the accumulation of ethanol, which was still present at concentrations >100 μl·liter −1 (ppm) in strawberry juice after their transfer to air for several days. Keeping strawberries in CA had residual effects on maintaining their flesh firmness and color, but had no significant effects on skin or juice color, titratable acidity, pH, soluble solids content, and ascorbic acid content. In general, as O 2 concentration was decreased or as CO 2 concentration was increased, the residual effects were more pronounced. The combinations of reduced O 2 and elevated CO 2 had more pronounced residual effects than either reduced O 2 or elevated CO 2 alone. Exposures to CA for 4 days had greater residual effects than exposure to CA for 1 to 3 days.
