READ MORECalcium carbide (CaC₂) is an important industrial chemical widely used in acetylene production, metallurgy, chemical manufacturing, and other industries. Calcium carbide has also historically been associated with fruit ripening. When calcium carbide comes into contact with moisture, it reacts to produce acetylene gas: CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂ Acetylene has effects similar to ethylene, a natural plant hormone that regulates the ripening process of many fruits. For this reason, calcium carbide has traditionally been used in some markets to accelerate the ripening of fruits such as bananas and mangoes. However, the use of calcium carbide for food ripening is restricted or prohibited in a number of countries and regions. Industrial-grade calcium carbide may also contain impurities that make it unsuitable for food-related applications. Therefore, businesses should always check local food-safety regulations and use only legally approved ripening methods for commercial fruit production and distribution.
