Introduction

As a natural polysaccharide gum produced by microbial fermentation, Gellan Gum has quickly become a "multifunctional raw material star" in the food, pharmaceutical, and cosmetic industries since its commercial application in the 1980s. Thanks to its excellent gelling properties, stability, and safety, it addresses the limitations of traditional gums (such as agar and gelatin) in heat resistance and dosage efficiency—making it a preferred choice in modern industrial formulations for its "low dosage, high gel strength" and "stable over a wide pH range" characteristics.

Part 1: What is Gellan Gum?

Basic Information

• Microorganism Introduction: Gellan Gum is produced by the fermentation of the gram-negative bacterium Sphingomonas elodea (formerly Pseudomonas elodea). It is processed into a powdered finished product through extraction, purification, and drying of the fermentation broth—with no geographical or seasonal restrictions associated with plant-based extractions.

• Production Process: The core process includes "strain cultivation → liquid fermentation → centrifugal sterilization → precipitation purification → drying and crushing → finished product testing." A closed fermentation system is used throughout to avoid external contamination and ensure product purity.

• Active Components: Its core structure is a polysaccharide composed of repeating tetrasaccharide units (glucose, glucuronic acid, rhamnose). Based on the content of acyl groups (acetyl and glyceryl groups), it is divided into high-acyl Gellan Gum (forms elastic gels) and low-acyl Gellan Gum (forms brittle gels), adapting to different application scenarios.

Part 2: Key Benefits and Mechanisms of Action

The functional advantages of Gellan Gum stem from its unique molecular structure, with specific benefits and mechanisms as follows:

• High-Efficiency Gel-Forming Ability: In the presence of cations (e.g., calcium, magnesium ions), low-acyl Gellan Gum polysaccharide chains rapidly form a "double helix-three-dimensional network structure." A gel with high strength can be formed with only 0.1%-0.5% addition—1/5 to 1/10 the dosage of agar—greatly reducing formulation costs.

• Wide-Range Stability: The gel remains stable over a pH range of 2.5-10.0, and is heat-resistant (melts only above 80℃) and freeze-resistant (no water separation after thawing at -20℃). This solves the problem of traditional gums being prone to failure in acidic beverages and high-temperature sterilized foods.

• Good Compatibility: It can work synergistically with other gums (e.g., xanthan gum, guar gum), sweeteners, pigments, and preservatives—enhancing gel elasticity and improving product texture (e.g., reducing the "hardness" of jelly).

• Safety and Low Burden: Evaluated by authoritative institutions such as the FDA and EFSA (European Food Safety Authority), Gellan Gum is non-carcinogenic, non-genotoxic, and non-digestible by the human body (a low-calorie ingredient), making it suitable for low-sugar, low-fat, and clean-label food needs. Multiple studies indexed in PubMed (e.g., 2019 study in Journal of Food Science) confirm its long-term safety in food applications.

Part 3: Wide-Ranging Application Industries

The versatility of Gellan Gum covers multiple industries, with specific application scenarios as follows:

• Food and Beverage Industry: The core application field, including—jelly/pudding (low dosage forms a chewy texture and reduces water separation), plant-based beverages (e.g., almond milk, oat milk, stabilizes proteins to prevent stratification), yogurt/probiotic drinks (enhances thickness and avoids whey separation), baked goods (as a modifier to improve dough water retention and bread shelf life), and canned foods (fixes pulp/ingredients to improve texture).

• Pharmaceutical Formulation Field: As a pharmaceutical excipient, it is used in capsule shells (replacing part of gelatin for vegan needs), oral suspensions (as a suspending agent to ensure uniform dispersion of drug particles), sustained-release formulations (regulates drug release rate to extend efficacy), and orally disintegrating tablets (improves tablet moldability and disintegration speed).

• Cosmetics and Personal Care: Added to mask serums (thickens and locks in moisture to extend skin hydration time), lotions/creams (stabilizes oil-phase ingredients to prevent stratification), and shampoos (adjusts viscosity and improves foam stability). It is mild and non-irritating, making it suitable for sensitive skin products.

• Other Fields: Pet food (e.g., cat treats, pet jelly, improves palatability and moldability) and microbial culture media (as a coagulant to replace agar and support uniform microbial growth).

Part 4: How to Choose High-Quality Gellan Gum?

The selection of high-quality Gellan Gum requires attention to "performance matching" and "compliance safety," with core criteria as follows:

• Clarify Acyl Group Type: Choose high-acyl (elastic gel, suitable for soft candies, spreads) or low-acyl (brittle gel, suitable for jelly, tablets) based on needs to avoid product failure due to mismatched types.

• Process and Purity: Ask the supplier whether a "pure strain fermentation + multi-stage purification" process is used to avoid off-odor or gel performance fluctuations caused by fermentation impurities (e.g., protein residues, pigments). Confirm purity ≥95% and no unknown additives through COA.
