Product Introduction

Gellan gum, a polysaccharide, is produced by microbial fermentation of Sphingomonas elodea, offering versatile gelling, texturizing, and stabilizing properties across a range of applications [1]. It is widely utilized in the food industry as a gelling agent, thickener, and stabilizer in various products, due to its ability to create clear, firm gels at low concentrations [2]. It is also used in the production of vegan food, to provide a similar texture to gelatin, which is derived from animals [3].

Production Process

The production of gellan gum begins with the fermentation of Sphingomonas elodea in a controlled environment, where the bacteria consume nutrients and produce gellan gum as a byproduct [4]. After fermentation, the gellan gum is recovered from the fermentation broth through precipitation usually by adding alcohol [5]. The recovered gum is then dried, milled, and standardized to meet specific quality requirements, tested, and packaged for commercial use [6].

Product Efficacy and Function

Gellan gum's primary functions include gelling, texturizing, and stabilizing aqueous solutions, it is widely used to create a variety of textures in food products, from firm gels to viscous solutions [7]. Due to its high transparency and ability to suspend particles, gellan gum enhances the visual appeal and stability of beverages and other food products [8]. Furthermore, it exhibits compatibility with various ingredients and maintains stability over a wide range of pH and temperature conditions [9].

Product Application Scenarios

In the food and beverage industry, gellan gum is used in the production of desserts, confectioneries, beverages, and dairy alternatives, due to its gelling and stabilizing properties [10]. It can also be found in plant-based milk and meat alternatives because it improves their texture and mouthfeel [11]. Beyond foods, gellan gum is used in pharmaceutical formulations, cosmetics, and personal care products as a stabilizer [12].

Packaging and Storage

Gellan gum is typically packaged in multi-layer kraft paper bags or fiber drums with inner polyethylene liners, available in various sizes, such as 25 kg or according to customer specifications, to protect against moisture and contamination [13]. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances, to maintain its quality and prevent degradation [14]. When stored properly, gellan gum has a shelf life of at least 24 months from the date of manufacture [15].
