Preservatives

Preservatives are added to food to prevent spoilage from microorganisms and extend shelf life by slowing changes in color, flavor, or texture. Common preservatives include antimicrobials and antioxidants. E numbers are codes used within the European Union to identify approved food additives and ensure their safety. Major companies involved in producing natural preservatives include Ajinomoto, Albemarle Corporation, and Cargill. Primary Information Services provides a database of information on preservatives, suppliers, related products and companies, patents, and materials safety data sheets.
