Fresh tomatoes (cv. Camonium) at the breaker-turning colour stage were stored at 12°C in air (i), air after exposure with 1-ppm 1-MCP for 24 h (ii), 3% O₂ + 5% CO₂ in nitrogen (iii), and in 3% O₂ + 5% CO₂ in nitrogen after exposure with 1-ppm 1-MCP for 24 h (iv). Initially and after 4, 6, 8 and 11 days of storage the following quality attributes were evaluated: colour of the epicarp, berry relative deformation, total soluble solids, and titratable acidity. In addition, respiration rate was measured o­nly for air treatments.

Exposure with 1-MCP resulted in a lower respiration rate, a higher titratable acidity, a slower colour development and berry firmness loss when tomatoes were stored in air. Effects of 1-MCP o­n tomatoes stored in controlled atmospheres was less noticeable with 1-MCP exposed berries presenting a slower firmness loss, an higher titratable acidity, and almost no difference in colour development.

No difference was observed between treatments for total soluble solids content. In general, exposure with 1-MCP resulted more effective in delaying ripening of tomatoes berries than controlled atmosphere with 3% O₂ and 5% CO₂
