Usage	Commonly used in food industry	Commonly used in cosmetics industry
Functionality	Forms gels in the presence of cations	Forms stable emulsions

Introduction

Gellan gum and sclerotium gum are both natural hydrocolloids that are commonly used in the food and cosmetic industries. They are both polysaccharides that have unique properties that make them valuable ingredients in various products. In this article, we will compare the attributes of gellan gum and sclerotium gum to help you understand their differences and similarities.

Source

Gellan gum is produced by the bacterium Sphingomonas elodea through fermentation. It is a water-soluble polysaccharide that is commercially produced through a controlled fermentation process. On the other hand, sclerotium gum is derived from the fermentation of the Sclerotium rolfsii fungus. This fungus produces a gel-like substance that is then purified and dried to create sclerotium gum.

Texture and Viscosity

Gellan gum is known for its ability to create gels with a wide range of textures, from brittle and firm to elastic and flexible. It can also produce fluid gels that have a smooth and creamy mouthfeel. Sclerotium gum, on the other hand, is primarily used as a thickening agent and stabilizer. It forms a viscous gel that is stable over a wide range of temperatures and pH levels.

Stability

Gellan gum is highly stable and can withstand a wide range of processing conditions, including high temperatures and acidic environments. It is also compatible with a variety of ingredients, making it a versatile ingredient in food and cosmetic formulations. Sclerotium gum is also stable under various conditions, but it is particularly resistant to shear forces, making it ideal for use in emulsions and creams.

Compatibility

Gellan gum is compatible with a wide range of ingredients, including sugars, salts, acids, and proteins. It can be used in combination with other hydrocolloids to create unique textures and functionalities in food and cosmetic products. Sclerotium gum is also compatible with many ingredients, but it is particularly effective at stabilizing emulsions and suspensions due to its thickening properties.

Applications

Gellan gum is commonly used in a variety of food products, including dairy alternatives, desserts, and beverages. It is also used in personal care products such as lotions, creams, and gels. Sclerotium gum is often used in skincare products, hair care products, and makeup formulations as a thickening agent and stabilizer. It is also used in some food products as a natural alternative to synthetic thickeners.

Conclusion

In conclusion, gellan gum and sclerotium gum are both valuable ingredients with unique properties that make them suitable for a wide range of applications. While gellan gum is known for its ability to create gels with varying textures, sclerotium gum is prized for its thickening and stabilizing properties. Both hydrocolloids offer stability and compatibility with a variety of ingredients, making them versatile options for formulators in the food and cosmetic industries.
