Although ripening of tomatoes can be retarded by low temperatures, storage under refrigeration can cause chilling injury and increase of fungal contamination. Use of atmospherics rich in CO₂ and low O₂can also slow down the ripening process of tomatoes. What exposure time is necessary for the concentration of CO₂ at the center of a spherical tomato of 8 cm diameter to change to 15% by volume of air inside the tomato? The initial concentration of CO₂ in air in the tomato is 2% by volume. The storage room and the surface of tomato are maintained at 18% by volume of CO₂. The effective diffusivity of CO₂ in the tomato was found to be 2.3 x 10-8 m²/s.
