Picked green and rock-hard, unripe tomatoes are loaded into trucks and taken to storage facilities where they are literally gassed. (Ethylene gas is what makes a tomato turn red.) Tomatoes naturally produce their own ethylene gas, and slowly redden as they ripen at their own pace, and that takes time.
What do they gas tomatoes with?
Most tomatoes today are picked green and transported unripe to protect them from bruising and spoilage. The green tomatoes are then ripened somewhat artificially by exposing them to ethylene gas. This is generally not done in the supermarket but at the produce distributors that supply local markets.

Ethylene promotes ripening of apples, avocados, bananas, citrus (degreening), dates, mangos, some melons, papayas, pears, persimmons, pineapples, and tomatoes.
What negative effect does gassing have on tomatoes?
The effect of ethylene gas upon fruit is a resulting change in texture (softening), color, and other processes. Thought of as an aging hormone, ethylene gas not only influences the ripening of fruit but may also cause plants to die, generally occurring when the plant is damaged in some manner.
How are supermarket tomatoes ripened?
Tomatoes, like bananas and avocados, give off ethene (or ethylene) gas, a natural plant hormone that regulates a plant’s growth and makes it ripen by converting the starch it stores into sugar.

What gas do bananas give?
ethylene
“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.

Workers may be harmed from exposure to ethylene oxide.
What happens if you eat ethylene oxide?
