What is the Medium Acyl content Gellan Gum and its advantages?

Medium acyl gellan gum is not a simple physical mixture of high acyl and low acyl gellan gum. It is a unique variant produced through a precisely controlled deacylation process, featuring specific content and distribution of acyl groups (acetyl and glyceryl).

Its production process is highly demanding, requiring controlled partial hydrolysis and deacylation of natural high acyl gellan gum after fermentation to precisely regulate the number of acyl groups on the molecular chains. It is this specific molecular structure, intermediate between high and low acyl types, that gives it unique application properties.

Key Unique Advantages

Special and Suitable Gelation Temperature

Gelation Temperature Range: 60°C - 65°C. This temperature is significantly lower than that of high acyl gellan gum (typically > 75°C) but higher than that of low acyl gellan gum.
Core Value: This temperature characteristic addresses a major challenge in high-solids (high sugar, high salt) applications. In traditional high-temperature gelation processes (e.g., using high acyl gellan gum for high-sugar gummies), the system may prematurely solidify (pre-gel) in pipelines or equipment before cooling to the gelation point, leading to difficulties in filling, clogging, and equipment cleaning. The moderate gelation temperature of medium acyl gellan gum allows the system to be processed and filled under relatively mild conditions, significantly enhancing production convenience and safety.

Excellent Texture and Mouthfeel

Medium acyl gellan gum perfectly inherits the texture advantages of high acyl gellan gum, forming gels that are soft, elastic, tough, non-breaking, and with excellent flavor release.

Compared to high acyl gels, its texture is firmer and less sticky, offering an ideal balance between "soft and chewy" and "crisp."

Superior Process Operability

Combined with its suitable gelation temperature and excellent dispersion and solubility, medium acyl gellan gum demonstrates better predictability and stability in complex formulation systems, with minimal batch-to-batch variation and ease of process scaling.

Main Application Areas

Based on the above advantages, medium acyl gellan gum is an ideal choice for the following high-value applications:

Application Area	Problems Solved and Value Provided
Plant-Based Soft Capsules	Capsule Shell: Flexible, elastic, crack-resistant, tightly sealed, leak-proof. Process: Easy to form and seal at moderate temperatures, ensuring high production efficiency. Claim: Pure plant-based fermentation source, meeting clean label and vegan requirements.
High-Solids Confectionery/Desserts (e.g., gummies, jellies, chocolate spreads, processed cheese)	Prevents Pre-gelation: Allows safe filling and molding in high-sugar/high-fat systems at relatively lower temperatures. Optimizes Texture: Provides a soft, elastic, and non-sticky perfect texture, enhancing product quality.
Fruit Simulation Gummies/Fruit Puree Products	Texture Simulation: Mimics the soft, elastic, and juicy texture of natural fruit pulp. Thermal Stability: Thermo-reversible gels facilitate subsequent processing (e.g., coating, packaging).
Sauces and Spreadable Products	Provides Structure: Maintains a stable semi-solid or spreadable texture at room temperature without dehydration or oil separation. Smooth Mouthfeel: Enhances the fullness and smoothness of the product.

Conclusion: Why Choose Medium Acyl Gellan Gum?

Medium acyl gellan gum represents an advanced application of gellan gum technology. Through precise molecular design, it strikes an optimal balance between the excellent mouthfeel of high acyl gellan gum and the convenient processing of low acyl gellan gum. For innovative food and nutraceutical developers pursuing high-quality texture, complex formulations (especially high-solids systems), and efficient, stable production, it is a strategic raw material capable of solving specific process challenges and enhancing product competitiveness.
