Why does starburst taste so juicy?

Starburst candies taste juicy primarily due to their high sugar content and the inclusion of fruit flavors that mimic the taste of real fruit juices. The chewy texture also contributes to the sensation of juiciness, as it releases flavor more intensely as you chew. Additionally, the use of citric acid enhances the tartness, further amplifying the perception of a fresh, juicy taste.
