Xanthan Gum

4 Best Substitutes For Xanthan Gum You Can Use

Whether you are new at the keto diet, or you have been following a keto diet for a long time, you are bound to miss the creamy, starchy soups, sauces, smoothies and juices at some point of your journey. 

Let’s be honest we all miss and crave a little ice cream or jello sometimes!

Of course, nowadays ketogenic options of all those foods are available in stores or online, and there also are plenty of recipes online that show you how to make them yourself. The one common ingredient that store-bought foods and the recipes have is xanthan gum

Xanthan gum is a commonly used food additive in the form of a powder that acts as a thickener, stabilizer, and emulsifier when added to liquid foods. Many store-bought foods already contain xanthan gum in them, and many recipes may require you to use it to achieve the wanted results when cooking. 

However, sometimes getting a hold of xanthan gum may be a bit of a problem. While it is sold at some grocery stores, others simply don’t have it. Ordering it on the internet means that you’ll most likely have to wait a few days until it arrives- and sometimes, waiting just isn’t an option! You just want to make your dish as soon as possible! 

Whatever your reason may be, we understand that sometimes using xanthan gum in your dishes isn’t possible. This is why we have created a list of the best keto-friendly substitutes for xanthan gum you can use to make your dishes!

And here they are:

#1. Agar-agar

Agar-agar is a plant-based additive that is used as a stabilizer, binding agent and thickener. It is contained in foods such as marshmallows, jello, and is often used as a plant-based substitute for gelatin.

What is agar-agar and how it is used?

Agar-agar is a mixture of two carbohydrates-the linear polysaccharide called agarose and a heterogeneous mix of small molecules which are called agaropectin. Those compounds are extracted from the Red Seaweed algae. (*)

It’s believed that it was first discovered in Japan by an innkeeper who noticed that his seaweed soup had gelatinous masses in it after it had been sitting in the cold for a night. 

Soon after the discovery, agar became a subject of chemical analysis, and after a few years, it found its way to the fields of microbiology as a solid medium for growing various microorganisms. After that, it just kept growing in popularity, and today it’s production fluctuates annually. 

Today, agar is still used both in the microbiological field and the culinary world.

In the culinary world, agar-agar is used to form gelatinous masses and help thicken and balance liquids. It is sold white or transparent forms in packages in the shape of strips or powder which you add to the liquid and then boil to activate it.

Agar-agar is used in many Asian cuisines, such as Japanese where it is used to make the traditional amitsu, the Philippine cuisine where it is used to make jelly bars and in Vietnamese cuisine where it is used to make thạch which are jelly layers of agar. It is also used in Russia where it is added to marmalades and jams. 

In the keto kitchen, agar-agar is used as a low-carb and low-calorie option mostly in recipes where you want more gelatinous results. When you want to use it as a substitute for xanthan gum, you should use twice as much agar-agar as xanthan gum in the recipe.
