Ethylene
Ethylene is commonly used to ripen fruits. It is a natural plant hormone that triggers the ripening process. Ethylene gas can be applied to fruits in controlled environments to speed up the ripening process and improve shelf life.

When calcium carbide comes into contact with water it creates acetylene gas that hastens the ripening of several fruits such as bananas and apples.
Ethylene gas is commonly used to ripen bananas. It is a natural plant hormone that triggers the ripening process by stimulating the production of enzymes responsible for fruit softening and color changes. Ethylene can be applied in controlled concentrations to accelerate the ripening of fruits like bananas.
To accelerate the ripening process of a mango, place it in a paper bag with a banana or apple. The ethylene gas produced by these fruits will speed up the ripening of the mango.
To slow down the ripening of fruit, store them in the refrigerator as the cold temperature can inhibit ripening enzymes. You can also separate fruits that emit ethylene gas, as it can speed up ripening. Additionally, wrapping fruits in paper or cloth can help absorb excess moisture and slow down ripening.
Ethylene gas, a natural by-product of bananas and other fruits, is what accelerates the ripening process of fruit. The riper a fruit is the more gas is emitted. Once green bananas arrive at their destination, they are placed in rooms and exposed to commercial ethylene for this purpose. A method to accelerate the ripening of other fruits, such as tomatoes, is to place them in a container with a fully ripened banana. The ethylene gas that the banana gives off will help ripen the tomato.
Ethylene is a plant hormone that naturally regulates the ripening process in fruits. It triggers the activation of enzymes that break down cell walls and starches, leading to the softening and sweetening of the fruit. By mimicking this hormone, ethylene gas can be used to artificially ripen fruits after they have been harvested.
Use of ethylene for ripening of the fruit is a commonpractice in different countries but due to high costand scarcity in terms of its availability, manydeveloping countries like use low-cost calcium carbide to ripen fruitEthylene has been found not harmful or toxic to humans in the concentrations found in ripening rooms.It affects the growth, development, ripening, and senescence (aging) of all plants.
Fruits ripen faster when wrapped because wrapping traps ethylene gas, a natural ripening hormone produced by the fruit. This increased concentration of ethylene accelerates the ripening process. Additionally, wrapping can help retain moisture and warmth, creating an ideal environment for ripening. In contrast, unwrapped fruits are exposed to air, which allows ethylene to disperse and slows down the ripening process.
Naseberries ripen faster when wrapped in newspaper due to the ethylene gas they emit during the ripening process. The newspaper traps this gas around the fruit, creating a higher concentration that accelerates ripening. Additionally, the dark and slightly insulated environment provided by the newspaper helps maintain warmth, further promoting the ripening process. This method is commonly used to enhance the ripening of various fruits.
