Cornstarch is a powdery ingredient made from the endosperm of corn kernels. It is most commonly found in the baking aisle of grocery stores, near other baking ingredients such as baking powder, baking soda and flour.
It is also sometimes called cornflour. Cornstarch is widely used as a thickener for sauces, gravies, custards, soups, puddings and other foods. It can also be used as a coating for fried foods, such as fried chicken or fish, to help keep the food moist and crispy.
It is important to remember to use cornstarch in a small amount, as it can quickly cause a food to become overly thick and sticky. Additionally, cornstarch is not the same as cornmeal and should not be used interchangeably in recipes.

What is a substitute for cornstarch?
When a recipe calls for cornstarch as a thickener, there are several different substitutes that can be used. Some of the most common substitutes are arrowroot, tapioca, potato starch, and flour. Each of these alternatives can provide the same thickening power and are usually interchangeable at a one-to-one ratio.
Arrowroot is a starchy root vegetable similar to a potato with a mild flavor that is often used as a thickener in many recipes, including sauces and soups. It is a great option for those who are gluten-free or vegan, since it does not contain gluten or animal products.
Tapioca is also a great option for gluten-free recipes. It is derived from the cassava root and has a smooth, creamy texture that thickens during cooking. It is best for dishes with a gentle simmer, since it can become overly thick with baking or boiling.
Potato starch is made from the endosperm of potatoes, and while it may not be as widely used as other starches, it still makes a great thickener. It adds a glossy shine to recipes and can be used in place of cornstarch, although it is not as strong a thickener.
Finally, there is plain flour, which is a very functional option for thickening sauces and gravies. It provides the same thickness when added to hot liquids, but it has the disadvantage of leaving a floury taste in the final dish.
Adding a small amount of butter or fat can help reduce the flavor.
Is cornstarch a thickening agent?
Yes, cornstarch is a great thickening agent. It is composed of long chains of glucose molecules, which makes it particularly effective at thickening liquids like sauces, gravies, and stews. When mixed with a liquid, an enzyme in cornstarch converts some of the glucose molecules into a substance known as maltodextrin, which gives the mixture a thicker texture.
Additionally, when heated, the molecules in cornstarch swell and gelatinize, trapping liquid particles and giving the liquid an even thicker consistency. Cornstarch is often used in place of flour to thicken sauces because it results in a much clearer, smoother texture.
It can also be used as a substitute for gluten-free thickeners, making it suitable for those with gluten sensitivities.
What is the chemical formula of cornstarch?
The chemical formula for cornstarch is C6H10O5. Cornstarch is a type of starch that is obtained from pieces of ground dried maize (corn) kernels by a process of grinding and sifting. Cornstarch is made up of relatively long chains of glucose molecules with the general formula (C6H10O5)n.
It has a slightly sweet taste, and is used as a thickening agent in many cooking and baking recipes. It is almost entirely composed of amylopectin, which is a polysaccharide made up of several thousands of glucose molecules.
Cornstarch is used to manufacture adhesives and it is commonly used for thickening sauces and gravies, and as a biscuit or cookie dough base.
Does cornstarch stop bleeding?
The answer is ‘yes’, cornstarch can be used as a topical agent to help stop bleeding. As an absorbent material, cornstarch can be applied directly to a wound to absorb excess blood and help seal off the damaged tissue.
It can also be used in combination with other products such as hydrogen peroxide or even salt water to help wash away any debris that is in the wound and help keep it from becoming infected. Additionally, the starch content in cornstarch can help to form a barrier over the wound, keeping bacteria and other contaminants out.
While cornstarch can be a useful tool in helping to stop minor bleeding, it should always be used with caution as large amounts applied too quickly can cause additional irritation to the skin and even cause the clot to loosen, leading to further bleeding.
Can you use baking powder instead of cornstarch?
No, baking powder cannot be used instead of cornstarch. Baking powder is a combination of a few common ingredients, including baking soda, cream of tartar, and, sometimes, cornstarch. A large part of its purpose when used in baking recipes is to create small bubbles in dough and batters, allowing them to rise and create a light, fluffy texture.
While baking powder contains some cornstarch, it’s always in a significantly smaller quantity than what is typically used in a recipe. The cornstarch in baking powder does not replace traditional cornstarch which is used for thickening ingredients and sauces.
Baking powder cannot create the same thickness as traditional cornstarch. In addition, it is not important to the rising of the dough, like it is with baking powder. Instead, it is important for a dish that needs the texture of a thick sauce or the glaze clinging on top of the food.
Is cornstarch the same as corn flour in Australia?
No, cornstarch and corn flour are not the same in Australia. Cornstarch is a finely ground white starchy powder made from the endosperm of a corn kernel, whereas corn flour is made from the ground kernels of the whole kernel corn and is finer, and lighter in colour than cornstarch.
Corn flour is a common flour-like product used in Australia while cornstarch is not as widely available. Cornstarch is used in food preparation as a thickener, whereas corn flour is often used as a batter or breading for fried foods or as a thickener in dishes such as soups and stews.
What is potato starch in Australia?
Potato starch in Australia is a product made from the starch extracted from potatoes. It is a naturally gluten-free and easily digestible product, making it a popular choice among many consumers in the area.
Although potato starch is a common food additive and thickening agent used in a variety of applications, it is most commonly used in baking. In baking, potato starch functions as a binder to help keep the shape of the baked good, as well as provide structure to the dough.
It is also used as a coating for French fries and other fried foods as well as a thickener for soups, sauces and gravies. In addition, potato starch helps improve the shelf life of food products, making it a popular choice among food processors.
Can you use corn flour as a thickener?
Yes, you can use corn flour as a thickener. It is a great gluten-free alternative to traditional flour-based thickening agents, like wheat flour or all-purpose flour. Corn flour is typically made from finely ground whole-kernel corn and has a finer texture than cornmeal.
When making a sauce or gravy, it is best to use a whisk and add the corn flour slowly to avoid clumping. You should also initially dissolve the corn flour in cold water to ensure an even consistency.
Generally, one tablespoon of corn flour to two tablespoons of cold liquid should thicken one cup of liquid. It’s important to remember that corn flour will continue to thicken as it cooks, so you may want to start with a smaller amount to avoid over-thickening.
Why is my corn flour not thickening?
The most likely cause is that you were not able to mix the corn flour evenly with the liquid. If you add corn flour to a pot of boiling liquid, it can quickly form clumps if you do not mix it consistently.
Once the clumps have formed, it can be difficult to get them to dissolve properly, resulting in a thinner consistency. Additionally, you may have used too much liquid or too little corn flour, resulting in the incorrect ratio.
Finally, the type of corn flour you are using may have an effect. Some types of corn flour are specifically designed for making sauces and gravies and may not be suitable for thickening. Check the label to make sure you are using the correct type of corn flour for your recipe.
Which is a better thickener flour or cornstarch?
The answer depends on what you are trying to achieve and the recipe you are using. Flour is a great thickener for stews, sauces, and gravies as it can be cooked at a very low temperature and added directly to the liquid without pre-mixing.
On the other hand, cornstarch is often used as a thicker for custards and pie fillings. It must be added to liquid and heated to the boiling point while stirring to completely dissolve. Cornstarch is a much better option because it creates a much smoother, more velvety consistency.
Additionally, cornstarch is more powerful and a little goes a long way and it won’t create a cloudiness that flour may create. However, if you are looking for a more neutral flavor, then flour may be the best choice as cornstarch imparts a slight sweetness.
Ultimately, it depends on the recipe being used and the desired end result.
