Wheat flour:

Just like cornstarch wheat flour is also made of grinding a grain in a milling process. But wheat flour is rich in fibers, proteins and starch. It is possible to swap cornstarch and wheat flour but we need more flour than cornstarch.

When using wheat flour as a thickener it is better to make a slurry beforehand. This avoids clumping of flour when added to a liquid mixture of food.

Arrowroot:

It is a starchy flour obtained from the roots of Maranta plants. To make the roots are dried yup and then ground into fine powders. The powder obtained is used as a thickener in cooking. It is rich in fiber and preferred over cornstarch because of that,

Potato starch:

Potato is a very starchy vegetable and is used because of its starch rich properties in many recipes. It is a common practice to use potato starch instead of cornstarch. It is also free of gluten so it is better to use for people with celiac disease.

It is substituted in 1:1 ratio and is used in the same amount as cornstarch is used. It also thickens more quickly than cornstarch or other grain starches.

Rice flour:

Just like wheat flour it is made by rice grain milling and is often used in Asia. It is also gluten free and rich in starch as well so it is preferred. The slurry of rice flour is also colorless and is used to thicken transparent mixtures

When using rice flour, it is added in double amounts of cornstarch. The paste can be made in both hot and cold water, or in a mixture of fat and water.

Flaxseeds:

Ground flaxseeds are absorbent in water and make a jelly-like appearance when mixed with water. Unlike cornstarch they don’t have a smooth texture and are gritty in nature. They are a good source of soluble fiber and used when going for fiber boost in recipes.

When using flaxseed as a thickener, one tablespoon of flaxseeds is added in four tablespoons of water. One tablespoon of flaxseed is equal to 2 tablespoons of cornstarch

These are some of the substitutes used when thickening a liquid mixture. One thing to keep in mind is not to use gluten based products like wheat flour when making a dish for celiac patients. Using cornstarch is preferred in recipes due to absence of gluten.
