Sugar coating

Sugar coating is a layer of sugar applied to the surface of a food product. It is typically made from refined sugars like sucrose, often mixed with water and sometimes other ingredients like glucose syrup or corn syrup to achieve the desired texture and adhesion. The coating is usually applied by dipping, spraying, or tumbling the food item in the sugar mixture, which then solidifies.

Manufacturers add sugar coatings primarily for sweetness and to create a desirable texture, such as a crisp or glossy finish. They can also help to preserve the food by forming a barrier against moisture loss or gain. Sugar coatings are commonly found on confectionery, baked goods, dried fruits, and some savoury snacks where a sweet counterpoint is desired.

Sugar itself is not regulated as a food additive in the UK, but its presence in foods contributes to overall sugar intake. The UK's Eatwell Guide advises that free sugars should not exceed 5% of total dietary energy. High intakes of free sugars are associated with an increased risk of dental caries and weight gain, according to the NHS. The World Health Organization (WHO) also recommends limiting free sugar intake to reduce the risk of noncommunicable diseases.
