The congress topics cover the whole avocado value chain, and will include fundamental and applied science and technology. The only exception is where a speaker has been specifically selected to give a key note presentation. Please note that we do not provide these recommendations as a replacement for technical ripening experts if having ripening problems or starting a ripening program, we suggest that professionals be consulted.The academic programme is being overseen by the Local Scientific Organising Committee and Local Marketing Organising Committee and will include keynote speakers, plenary sessions, poster sessions and three breakout sessions covering a wide range of topics.The abstract process ensures all presentations are reviewed and assessed by these committees prior to presentation at the congress. While we have made great effort to provide accurate and current ripening techniques, Catalytic Generators makes no warranties regarding these recommendations or the applicability of such information to a particular ripening operation. These recommendations were amassed from a diverse number of sources for use by clients of Catalytic Generators, LLC. A great resource for any Fruit Ripener is a publication from UC Davis entitled “ Fruit Ripening & Ethylene Management.” Ripened avocados are less susceptible to chill damage they can be stored as low as 36☏ (2☌).įor more information on avocados and other fruits, please visit the web site of UC Davis Postharvest Technology Center. If chilled before ripening, the fruit will not ripen properly.

Chilling causes grayish-brown discoloration of the skin and flesh. Chilling injury will occur, and the longer avocados are held at low temperatures, the more severe the injury that will be caused. CautionĬAUTION: Do not hold mature green, unripe avocados at pulp temperature below 40☏ / 4.5☌. Once ripening has reached the desired degree of firmness, lower the pulp temperature to 40-42☏ (4.5 to 5.5☌). Ripened fruit may have the stem end button become more pliable indicating the softness process is beginning.
The fruit should be ready to ship within 3-6 days depending on the season, pulp temperature and degree of firmness. Pulp TemperatureĬheck pulp temperature at least twice per day and maintain proper pulp temperature. If automatic ventilation is not in place, be sure to vent approximately every 12 hours by opening the doors for 20 minutes even while applying ethylene. Anything above 1% may retard ripening or cause “checkerboard” ripening within the room.
Carbon dioxide (CO2)Ĭarbon dioxide (CO2) will build up during ripening. Please note that all rooms vary in terms of how air-tight they are, so if more precise PPM determination is required, air testing for ethylene PPM levels is recommended.

To achieve 100 ppm, the generator setting will depend on the size of the ripening room. Use the recommendations below as a guide, and make sure to check avocado firmness (here’s where to find avocado firmness testers: QA Supplies) to know when to stop ethylene application: Apply 100 ppm ethylene exposure time is dependent upon season of harvest, age of fruit, and maturity level at harvest.
Once the fruit pulp temperatures stabilize, place a Catalytic Generator in the room, fill it with Ethy-Gen® II Concentrate. Leave 1½ feet / 0.5 m between walls and pallets and at least 6 inches / 150 mm between pallets. If not using pressurized ripening rooms, air stack the boxes (at least 2″ / 50 mm between boxes) to have proper air circulation. Before ripening begins, the fruit pulp temperature should be raised to 65-68☏ (18-20☌). Mature green avocados should be shipped at 41-51☏ (5 to 10.5☌, pulp temperature). Please note that avocados produce more heat than bananas! Cooling may be slower than is needed when using banana rooms to ripen avocados.Įarly season avocados may take longer to ripen than middle to late season ones.
