Pre-Conditioning & Ripening Manual
Keys to Success for Ripening Avocados
![]() ![]() |
Ethylene Conditioning:
- The room should be heated, allowing the pulp temperature to rise and stabilize between 60°F - 68°F
- Use an Ethylene Generator or bottled ethylene to maintain ethylene at 10 - 100 ppm throughout the entire conditioning cycle (for bottled ethylene follow label requirements)
- Vent the room at least two (2) times per day for 20 minutes or use continuous exhaust fans to minimize the Carbon Dioxide level
DO NOT EXCEED 1 percent CARBON DIOXIDE LEVELS
- Maintain a 60°F - 68°F pulp temperature during the conditioning cycle
*Temperatures above 77°F will stop ripening*
