The term 'sweetening agent' refers to substances that are added to food and beverages to make them taste sweeter. Two common sweetening agents are GLYCEROL (8 letters) and SUGAR (5 letters). GLYCEROL is a colorless, odorless, viscous liquid that is used in many food products, such as candy, baked goods, and ice cream. SUGAR is a carbohydrate that is found naturally in fruits and vegetables, but it is also widely used as an additive in processed foods and drinks. Both GLYCEROL and SUGAR are used to sweeten food and beverages, making them more palatable.
