Green Icing: Powdered Sugar

Powdered sugar, also known as confectioners' sugar or icing sugar, is granulated sugar that has been finely ground into a powder. It typically contains a small amount of an anti-caking agent, such as cornstarch, to prevent clumping. It is derived from sugar cane or sugar beets.

Manufacturers use powdered sugar primarily as a sweetener and for its fine texture. It is a key ingredient in icings, frostings, and glazes, providing a smooth consistency. It is also used for dusting baked goods and in some dessert recipes.

Powdered sugar is generally recognized as safe (GRAS) by the FDA. As a form of sugar, it provides calories and contributes to the "added sugars" content of foods. The 2025-2030 Dietary Guidelines for Americans advise no amount of added sugars is recommended, and at most 10 grams of added sugars per meal. JECFA has evaluated sucrose and set an acceptable daily intake.
