Citrus ripening tips

Many types of Citrus Fruits, including lemons, grapefruit, oranges, and tangerines, can be degreened by exposure to 1-10 ppm ethylene for 1-3 days. The temperature in which degreening should occur is in the range of 68 to 86°F (20 to 30°C). CATALYTIC GENERATORS offers several generators that can be used to manufacture ethylene in the 1 – 10 ppm range. The right machine for the job depends upon the degreening room size and how air-tight it is:- For rooms up to 25,000 ft3 we recommend the Citrus Generator- For rooms larger than 25,000 ft3 we recommend the Easy-Ripe Generator- For large degreening operations with several expansive rooms requiring multiple generators, we recommend the CRS – Centralized Ripening System Temperature, ethylene level and exposure time that should be used for each type of citrus and cultivar varies, so for further recommendations we suggest you to contact your local extension agent, university expert, or other experienced citrus postharvest specialist. A great resource for postharvest information is The University of California at Davis or The University of Florida. More information
