Confection, such as chewing gum, is often coated with a hard shell of sugar or polyol (sugar free). This hard coating protects the chewing gum and provides a pleasant, often colourful, appearance and a nice crunch. This type of candy is named 'hard panned candy'. The coating is created by spraying layers of a concentrated solution and drying it. This process is very time consuming (up to 8 hours) as multiple layers (40-150) are needed to make a strong shell.
Sucrose esters are known for their effect on sugar crystallisation. Addition of sucrose esters to the spraying solution have multiple benefits:
These benefits can also be used in sugar free polyol panning.
