The Effects of Ethylene during the Ripening of Climacteric Fruits
Ethylene production is closely associated with fruit ripening in climacteric fruits, and is the plant hormone that regulates and coordinates the ripening process; colour development, aroma production and texture. Typically, climacteric fruit will generate barely detectable amounts of ethylene until ripening when there is a burst of production.
Ethylene as a ripening trigger is used commercially with many fruits including bananas, avocados and early-season kiwifruit to ensure that fruit are ripe when required. If the fruit is to be stored for a long time, then ambient ethylene must be removed from the room (usually by scrubbing this gas from the cool room).
The following tables shows some appropriate ethylene gas levels, ethylene exposure times and temperatures for ripening certain commodities. Relative humidity should always be high, generally in the range of 80-100% for all commodities.Appropriate ethylene and temperature levels for ripening and storage Commodity Ethylene Gas (ppm) Exposure Time (hr.)
