Icing: Icing Sugar

Icing sugar, also known as powdered sugar or confectioners' sugar, is a very finely ground form of sucrose (table sugar). It often contains a small amount of an anti-caking agent, such as cornstarch or tapioca starch, to prevent clumping.

Manufacturers use icing sugar primarily as a sweetener and for its fine texture, which makes it ideal for icings, glazes, and dusting on baked goods. It dissolves quickly and creates a smooth consistency in frostings and desserts.

Sugar, including icing sugar, is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). The 2025-2030 Dietary Guidelines for Americans recommend no specific amount of added sugars, advising consumers to limit intake and consume at most 10 grams of added sugars per meal. High intake of added sugars can contribute to excess calorie intake and may be associated with various health concerns. JECFA has evaluated sucrose and did not set a numeric limit (ADI not specified).
