As a horticultural expert with a focus on postharvest physiology, I can provide you with a comprehensive understanding of the chemical that plays a crucial role in the ripening of fruits.
Ethylene is the primary plant hormone responsible for the ripening of fruits. It is a simple hydrocarbon with the chemical formula C2H4. Ethylene is naturally produced by plants as they mature, and it acts as a signal to initiate the ripening process. This hormone influences a variety of biochemical reactions within the fruit, leading to changes in color, texture, flavor, and aroma.
The ripening process is a complex one, involving the breakdown of complex molecules into simpler ones, which makes the fruit softer, sweeter, and more palatable. Ethylene triggers the production of enzymes that break down cell walls, pectins, and other structural components, which leads to the softening of the fruit. It also promotes the conversion of starches into sugars, which sweetens the fruit, and the synthesis of pigments, such as anthocyanins, which can change the color of the fruit.
In commercial settings, ethylene is often used to artificially ripen fruits that are harvested while still green and unripe. This controlled ripening allows for better handling and transportation of fruits, as well as a more consistent product for consumers. Ethylene is typically applied as a gas, and it can be generated from various sources, including ripe fruits themselves, which release ethylene as they mature.
Now, regarding the use of calcium carbide, it is indeed used in some regions as a means to artificially ripen fruits. When calcium carbide reacts with water, it generates acetylene gas (C2H2), which has similar effects to ethylene in terms of promoting fruit ripening. Acetylene acts as a plant growth regulator, mimicking the action of ethylene and accelerating the ripening process. However, it's important to note that the use of calcium carbide for this purpose is controversial due to potential health and safety concerns, as acetylene is a flammable and explosive gas.
It's also worth mentioning that while ethylene and acetylene can speed up the ripening process, they do not improve the nutritional quality of the fruit. The use of ethylene in controlled environments is generally considered safe and is widely accepted in the industry for its ability to ensure that fruits reach consumers at their peak ripeness.
In conclusion, ethylene is the key chemical that naturally ripens fruits, and its controlled application is a common practice in the industry to ensure the quality and consistency of fruits available to consumers. The use of calcium carbide to produce acetylene for ripening is an alternative method, but it comes with its own set of challenges and concerns.

Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is quite similar in its effects to the natural ripening agent, ethylene. Acetylene acts like ethylene and accelerates the ripening process.
