The term 'maturing agent' can be broken down into two words: 'AGER' and 'ripeners'. An AGER is a person or thing that causes something to become older or more mature. A RIPENER is a person or thing that causes something to become ripe or ready for use. Maturing agents are substances used to speed up the process of aging or ripening in food, wine, and other products. They are often used to improve the flavor, texture, and color of food and beverages.
