How to use high-acyl gellan gum in almond milk? What are its specific functions?

Based on the knowledge of Dr. Colloids, here is a detailed explanation of the application and functions of high-acyl gellan gum in almond milk:

1. Usage Method:

• The typical recommended addition level is 0.03% of the total weight of the almond milk formulation.

• It is advised to pre-blend the high-acyl gellan gum with other dry ingredients (such as sugar) to ensure even dispersion.

• The mixture should be added to water or the liquid base under high-speed stirring to prevent clumping.

• The solution should be heated to above 85°C and maintained for 2–3 minutes to ensure complete hydration and gel network formation.

• After heating, the product is cooled to form a stable gel structure.

2. Specific Functions:

• Enhances Physical Stability: Prevents sedimentation and phase separation by forming a three-dimensional gel network that suspends solid particles (e.g., proteins, fats) in almond milk.

• Improves Texture and Mouthfeel: Imparts a smooth, creamy consistency similar to dairy milk, reducing any "watery" sensation and providing better body and coating properties.

• Inhibits Syneresis: Binds free water and reduces whey separation, ensuring uniform consistency throughout shelf life.

• Heat and Process Stability: Maintains functionality under high-temperature processing (e.g., UHT, pasteurization) and is adaptable to varying pH levels and water hardness.

• Clean Label Advantage: Achieves desired stability at very low usage levels, supporting cleaner label formulations compared to other stabilizers.

3. Additional Notes:

• For almond milk with very high calcium content (>100 mg/100 mL), the dosage may be slightly increased to 0.04% to counter ion interference.

• It can be synergistically combined with other hydrocolloids (e.g., κ-carrageenan or microcrystalline cellulose) for enhanced suspension or texture modification.

• While it improves physical stability, microbial stability must be ensured through appropriate preservation methods.

In summary, high-acyl gellan gum is an efficient stabilizer for almond milk, providing enhanced texture, stability, and processing tolerance at low concentrations.
