(1) Taste: Sweetness is one of the indicators of many foods. To make food and beverages palatable, a certain amount of sweetener needs to be added.
(2) Flavor regulation and enhancement: Sweetness is generally required in pastries; in beverages, flavor adjustment includes the "sugar-acid ratio." Sweeteners can give products a good flavor while preserving a fresh taste.
(3) Flavor formation: Sweetness and the flavor of many foods are complementary. The flavor of many products is produced by the combination of flavor substances and sweeteners, so many foods contain sweeteners.
