Dusting Sugar

Dusting sugar is a very finely ground form of granulated sugar, often mixed with a small amount of an anti-caking agent like cornstarch. This fine texture allows it to be easily sprinkled and prevents clumping. It is made by mechanically grinding sucrose crystals into a powder.

Manufacturers use dusting sugar primarily for decorating baked goods, such as cookies, cakes, and pastries, to provide a visually appealing, delicate white finish. Its fine texture also helps it dissolve quickly, making it suitable for glazes and icings where a smooth consistency is desired.

As a form of sugar, dusting sugar is generally recognized as safe (GRAS) by the FDA. The 2025-2030 Dietary Guidelines for Americans recommend no amount of added sugars, and at most 10 grams of added sugars per meal. Excessive intake of added sugars can contribute to health concerns like dental cavities and increased calorie intake. JECFA has evaluated sucrose and did not set a numeric limit (ADI not specified), considering it a food ingredient rather than an additive requiring an ADI.
