Calcium Carbide, also called "stone" by fruit traders, is a friable product. It has a strong odor similar to that of the sulfur. Solid, its color is identical to that of potash. This is what is used by many traders to precipitate fruit maturation. While they are appreciated for their nutrients indispensable to our health, they are increasingly unfit for consumption. This is the observation that emerges, in the light of the conditions of their ripening. These toxic and dangerous products are on sale in the cities of mango production areas and their surroundings. An unfortunate situation continues and does not stir anyone. Not even the political and health authorities who have the duty to guarantee food hygiene.

In the mango production areas, mainly south Asia, southeast Asia and Africa, the mango distributors always ask about the use of calcium carbide to ripen the fruits. In the market, retailors, to speed up the process of ripening their goods, use calcium carbide, but they cannot tell you. "This chemical releases a lot of toxic gas and living next to the market, we can't breathe at night". It always happens that people pack pieces of calcium carbide in wet rags and place them in containers containing unripe fruit while covering them. The calcium carbide then releases heat which guarantees the forced maturity. In fact, it remains on the surface of the fruits before evaporating. What constitutes a risk to the environment. None of the distributors want to answer the questions about calcium carbide. Visibly, they know of the danger of their fruit maturation formula.

In reality, when fruits ripen, many biochemical changes occur. The most obvious are the colour, aroma and firmness of the fruit. In some countries, the use of calcium carbide (CAC2) is allowed to accelerate the maturation process. This allows producers to choose ripe fruits faster and manage them when they are green and less susceptible to bruising or damage. The calcium carbide combines with the humidity of the air to release a gas called acetylene produced during maturation. Calcium carbide contains arsenic and phosphorus that can be lethal to humans and animals. It is a product to be used with all possible precautions. Several serious health risks are stated by the specialists. There are "carcinogenic risks". The symptoms of intoxication are vomiting, diarrhea, numbness, headaches and dizziness.

Ethylene is a hydrocarbon gas. Ethylene gas in fruits is a naturally occurring process resulting from the ripening of the fruit, or may be produced when plants are injured in some way.The effect of ethylene gas upon fruit is a resulting change in texture (softening), color and other processes. So as an aging hormone, ethylene gas influences the ripening of fruits safely and naturally.
