Ripening agents are substances used to accelerate the ripening process of fruits. These agents can be natural, such as ethylene gas, which is produced by many fruits as they mature. Ethylene helps to soften the fruit, enhance its flavor, and change its color, making it more appealing for consumption. In addition to ethylene, other ripening agents include chemicals like calcium carbide, which is sometimes used in commercial settings. While effective, the use of certain synthetic ripening agents can raise health concerns, leading to regulations in many countries to ensure food safety and quality.
