Powdered sugar, also known as confectioner’s sugar or icing sugar, is a staple ingredient in many baking recipes. It’s used to add sweetness and texture to a variety of treats, from cakes and cookies to frostings and glazes. However, have you ever stopped to think about what’s really in powdered sugar? While it may seem like a simple ingredient, powdered sugar often contains a secondary ingredient that plays a crucial role in its texture and performance: cornstarch.
What is Cornstarch, and Why is it Added to Powdered Sugar?
Cornstarch is a carbohydrate extracted from the endosperm of the corn kernel. It’s a fine, white powder that’s commonly used as a thickening agent in sauces, soups, and baked goods. In the context of powdered sugar, cornstarch serves as an anti-caking agent. This means that it helps to prevent the sugar from becoming lumpy or clumpy, ensuring that it remains smooth and easy to use.
But why is cornstarch necessary in powdered sugar? The answer lies in the nature of sugar itself. Sugar is a hygroscopic substance, meaning that it has a tendency to absorb moisture from the air. When sugar is powdered, its surface area increases, making it even more prone to absorbing moisture. This can cause the sugar to become lumpy or clumpy, which can be difficult to work with.
The Role of Cornstarch in Preventing Caking
Cornstarch helps to prevent caking in powdered sugar by absorbing excess moisture and reducing the sugar’s hygroscopic properties. When cornstarch is added to powdered sugar, it forms a thin layer around each sugar particle, preventing them from sticking together. This ensures that the sugar remains smooth and easy to use, even in humid environments.
But how much cornstarch is typically added to powdered sugar? The answer can vary depending on the manufacturer and the intended use of the sugar. However, a common ratio is to use 3-5% cornstarch by weight. This means that for every 100 grams of powdered sugar, 3-5 grams of cornstarch are added.
The Benefits of Using Cornstarch in Powdered Sugar
The addition of cornstarch to powdered sugar offers several benefits, including:
- Improved texture: Cornstarch helps to ensure that powdered sugar remains smooth and easy to use, even in humid environments.
- Increased shelf life: By reducing the sugar’s hygroscopic properties, cornstarch helps to prevent the growth of mold and bacteria, extending the shelf life of the sugar.
- Enhanced performance: Cornstarch can help to improve the performance of powdered sugar in certain recipes, such as frostings and glazes, by preventing the sugar from becoming too thin or too thick.
Potential Drawbacks of Using Cornstarch in Powdered Sugar
While the addition of cornstarch to powdered sugar offers several benefits, there are also some potential drawbacks to consider:
- Flavor: Some bakers may detect a slightly starchy or chalky flavor in powdered sugar that contains cornstarch.
- Texture: If too much cornstarch is added to powdered sugar, it can affect the texture of the final product, making it seem gritty or chalky.

What is the secret ingredient in powdered sugar?
The secret ingredient in powdered sugar is cornstarch. Cornstarch is added to powdered sugar to prevent clumping and improve its flow. It helps to absorb moisture from the air, which can cause the sugar to become lumpy or sticky. By adding cornstarch, manufacturers can ensure that their powdered sugar remains smooth and easy to use.
The amount of cornstarch added to powdered sugar can vary depending on the manufacturer and the intended use of the product. Some powdered sugars may contain as little as 1-2% cornstarch, while others may contain up to 5% or more. The exact ratio of cornstarch to sugar is not always disclosed, but it is generally considered to be a small percentage of the total ingredients.
Why is cornstarch added to powdered sugar?
Cornstarch is added to powdered sugar to improve its texture and prevent clumping. When sugar is powdered, it can become electrostatically charged, causing it to cling together and form clumps. The cornstarch helps to absorb moisture and reduce the electrostatic charge, making it easier to sift and mix the sugar. This is especially important in commercial baking and food production, where consistency and ease of use are crucial.
In addition to preventing clumping, cornstarch also helps to improve the flow of powdered sugar. This makes it easier to measure and pour, reducing the risk of spills and messes. The cornstarch also helps to prevent the sugar from becoming too dense or heavy, which can affect the texture of baked goods and other products.
What is the typical ratio of cornstarch to sugar in powdered sugar?
The typical ratio of cornstarch to sugar in powdered sugar can vary depending on the manufacturer and the intended use of the product. However, a common ratio is around 3-5% cornstarch to 95-97% sugar. This means that for every 100 grams of powdered sugar, there may be 3-5 grams of cornstarch.
It’s worth noting that some manufacturers may use a higher or lower ratio of cornstarch to sugar, depending on their specific needs and preferences. Some powdered sugars may also contain other ingredients, such as anti-caking agents or flavorings, which can affect the overall ratio of cornstarch to sugar.
