Food chemicals are substances that are intentionally added to food products during processing, manufacturing, packaging, or storage to enhance their quality, safety, taste, texture, appearance, and shelf life. These chemicals play an important role in modern food production, ensuring that food remains fresh, safe, and appealing from the time it is produced until it reaches the consumer. Food chemicals may be derived from natural sources such as plants and minerals, or they may be synthetically manufactured to achieve specific functional properties.
