Gellan gum is a natural food thickener that is commonly used in the food industry. It is a polysaccharide produced by fermentation of the bacterium Sphingomonas elodea. Gellan gum is known for its unique gelling properties, as it can create firm and elastic gels at low concentrations.

This food thickener is used in a variety of food products, including dairy products, beverages, and confectionery items. It is often used as a replacement for other thickeners, such as carrageenan and agar, due to its superior gelling properties.

Gellan gum is also known for its stability under various conditions, such as high temperatures and acidic or alkaline environments. This makes it an ideal ingredient for food products that require stability over a wide range of processing and storage conditions.

Overall, gellan gum is a versatile and effective food thickener that can help improve the texture and stability of various food products.
