Is cornstarch better than xanthan gum?

Cornstarch and xanthan gum are both used as thickening agents, but they have some differences in terms of their properties and how they are used. Here are a few key points to consider:

• Cornstarch is a starch that is derived from corn, while xanthan gum is a polysaccharide that is produced through fermentation.
• Cornstarch is a very effective thickening agent and is often used in sauces, gravies, and other foods to give them a smooth, creamy texture. It is especially useful for thickening acidic liquids, as it does not break down in the presence of acid.
• Xanthan gum is a more versatile thickening agent than cornstarch, as it can be used to thicken both acidic and basic liquids. It is also more stable over a wider range of temperatures and can be used to stabilize emulsions and foams.
• Cornstarch tends to break down over time and may lose its thickening ability if it is heated for too long or if it is frozen and thawed. Xanthan gum, on the other hand, is more stable and maintains its thickening properties over time.

In general, cornstarch is a good choice for thickening sauces and other foods that will be consumed soon after they are prepared.

Xanthan gum is a better choice for products that need to be stable over a longer period of time, or for products that will be frozen or subjected to other extreme conditions.
