So, what is ethylene gas? Ethylene gas in fruits and vegetables is actually a plant hormone which regulates the plant's growth and development as well as the speed at which these occur, such as hormones do in humans or animals.

What is ethylene gas in fruit ripening?
Most fruits produce a gaseous compound called ethylene that starts the ripening process. When harvested after the rapid rise in ethylene, they quickly soften and senesce in storage. ... Other varieties have a slower rise in ethylene and slower ripening rate.
What is ethylene gas?
Ethylene gas is a major plant hormone that influences diverse processes in plant growth, development and stress responses throughout the plant life cycle. Responses to ethylene, such as fruit ripening, are significant to agriculture.
What is ethylene gas used for?
Ethylene gas (C₂H₄) is naturally occurring in produce, and is commonly used to aid in the ripening process of many common fruits (e.g., bananas, kiwifruit). However, it is also a worry for produce handlers because exposure to ethylene-sensitive produce items can result in detrimental effects for those produce items.
Is ethylene harmful to humans?
Ethylene has been found not harmful or toxic to humans in the concentrations found in ripening rooms (100-150 ppm). In fact, ethylene was used medically as a anesthetic in concentrations significantly greater than that found in a ripening room.
Which fruit has the most ethylene gas?
Build-up of the chemical compound ethylene gas will cause them to go off, so apples, melons, apricots, bananas, tomatoes, avocados, peaches, pears, nectarines, plums, figs, and other fruits and vegetables should be kept separate as these produce the most ethylene.
How should fruits that produce ethylene gas be stored?
Ethylene triggers the ripening process; and exposure to ethylene can cause vegetable deterioration. It is recommended that you store your fruits and vegetables separately in the refrigerator. See products noted as ethylene producer or ethylene sensitive in the Storage Guides below). It's easy to ripen fruit at home!
What causes ethylene gas?
Ethylene is a natural plant hormone released in the form of a gas. ... This is the principle behind placing unripe fruit inside a paper bag or other closed container, which concentrates the ethylene. Adding another high ethylene fruit, such as a ripe apple or banana, may also speed up the process.
Are bananas ripened with gas?
"Bananas make other fruit ripen because they release a gas called ethene (formerly ethylene)," added Dr Bebber. "This gas causes ripening, or softening of fruit by the breakdown of cell walls, conversion of starches to sugars and the disappearance of acids.
Which foods produce ethylene gas?
ETHYLENE PRODUCING FOODS:
- Apples.
- Apricots.
- Avocados.
- Ripening bananas.
- Cantaloupe.
- Cherimoya.
- Figs.
- Honeydew.
Where can I get ethylene gas?
Ethylene may be produced not only in ripening fruit, but from internal combustion exhaust engines, smoke, rotting vegetation, natural gas leaks, welding, and in some types of manufacturing plants.
What is the gas that ripens fruit?
Mechanisms of Fruit Ripening
One of the most widely used chemicals for speeding up the ripening process is ethylene, so much so that it is known as 'the ripening hormone'.
How do you make ethylene gas at home?
Open one plastic bag and place the two bananas in the bag. Seal the bag tightly and make sure that there is little air in the bag. You want to ensure that the bag is not free from all air as the oxygen will help the fruit to produce ethylene more effectively.
