Xanthan gum is a popular food additive used in cooking and baking, especially in gluten-free recipes. But how is xanthan gum made? And how can you use it in your recipes?
Read on to find out about the process of making xanthan gum, and why this stabiliser and thickener should be a pantry staple in every plant-based kitchen.
What Is Xanthan Gum?
Xanthan gum is made by fermenting sugar. The sugar is fermented by the bacteria xathomonas campestris - this is where xanthan gum gets its name - which forms a thick liquid. Adding alcohol to this liquid makes a solid, which is then dried and turned into a powder.
Both home cooking and industrial food production use xanthan gum in its powder form. It is also used in producing toothpaste, cosmetics, glue, paint and other goods.
Xanthan gum was first produced in the United States in the early 1960s, after being discovered by chemist Allene Rosalind Jeanes. It is an approved food additive (also known as E415) used across the UK, Europe and North America.
Xanthan gum is used as an emulsifier, stabiliser and thickener in commercial food production and home baking. Because it has little to no flavour, the powder can be used in cooking without changing how the food tastes.

Xanthan Gum Benefits
The main benefit of xanthan gum is that it can be used in vegan and gluten-free baking. However, there are also some studies that suggest xanthan gum can help to lower blood sugar and cholesterol, and relieve constipation.
It is important to note that decreased blood sugar and cholesterol were only recorded when people consumed 6-10 servings of xanthan gum per day as part of research studies, which is much more than people would use in everyday cooking.
The effect on blood sugar was due to the xanthan gum slowing digestion and therefore reducing blood sugar spikes after meals.
Consuming large amounts (more than 15g) of xanthan gum has also been linked to increased bowel movements, which may help to relieve constipation.
How To Use Xanthan Gum
Because of its thickening properties and neutral taste, xanthan gum can be used in a range of foods, especially when you're looking for a creamy texture without the dairy. It's perfect for chilled desserts like ice cream and jelly since xanthan gum doesn't need cooking to work.
