What exactly is the 'coating' on these marmalades and what does it do? — “Smart Sweets” Barberry Marmalade Sugar-Free, 80 g — Di & Di

The coating is a light, dry layer applied to the surface of each marmalade piece. It is made from a blend of corn flour, amaranth flour, and dried Jerusalem artichoke. The primary purpose of this coating is to make the texture less sticky to the touch, which is a common issue with gelled, pectin-based sweets. This makes the pieces easier to handle, keeps them from clumping together in the package, and provides a pleasant, slightly powdery mouthfeel that contrasts with the soft, chewy interior.

Ingredients like amaranth and Jerusalem artichoke are often chosen for their functional properties in gluten-free baking and confectionery, contributing to the fine, non-gummy texture of the coating. This formulation is particularly practical for a snack meant to be carried in a bag or pocket, as it prevents the pieces from becoming a sticky mess.
