📌 Introduction

One of the most frequently asked questions from food and beverage manufacturers is:

“When should High Acyl Gellan Gum be added during production, and how should it be hydrated properly?”

Because High Acyl Gellan Gum is typically used at very low levels (0.01%–0.10%), incorrect incorporation can result in lump formation, incomplete hydration, poor suspension, sedimentation, or texture defects.

This practical guide explains exactly how to disperse, hydrate, and incorporate High Acyl Gellan Gum (E418) across dairy products, plant-based beverages, desserts, sauces, meat products, and pet food applications.

🔬 What is High Acyl Gellan Gum?

High Acyl Gellan Gum is a naturally fermented polysaccharide produced by Sphingomonas elodea. Unlike Low Acyl Gellan Gum, High Acyl Gellan Gum forms soft, elastic and flexible gels while providing excellent suspension and stabilization properties.

Main Functions:

  • ✔ Suspension of particles and pulp
  • ✔ Protein stabilization
  • ✔ Texture enhancement
  • ✔ Water retention
  • ✔ Syneresis control
  • ✔ Freeze-thaw stability
  • ✔ Soft elastic gel formation

⚠ Why High Acyl Gellan Gum Should Never Be Added Directly

Since the dosage is extremely small, direct addition often causes localized hydration, creating lumps commonly known as "fish eyes."

Common Problems Caused by Direct Addition:

  • ❌ Lumping
  • ❌ Incomplete hydration
  • ❌ Poor suspension performance
  • ❌ Uneven texture
  • ❌ Reduced shelf-life stability

For best performance, High Acyl Gellan Gum should first be dispersed and hydrated before entering the main formulation.

🔥 Recommended Hydration Method

Step 1 – Dry Premixing

Premix High Acyl Gellan Gum with another dry ingredient such as sugar, maltodextrin, milk powder or protein powder.

Recommended Ratio:

1 Part High Acyl Gellan Gum
10–20 Parts Sugar or Dry Ingredient

This greatly improves dispersion and minimizes lump formation.

Step 2 – Dispersion in Water

Under continuous agitation, slowly add the premix into water.

Step 3 – Hydration

Parameter Recommended Condition
Water Temperature 85–90°C
Mixing Time 15–30 Minutes
Agitation Moderate to High
Water Quality Potable Water

Complete hydration normally occurs only after heating to 85–90°C.

💧 How Much Water Should Be Used?

A concentrated stock solution is usually prepared before adding to the final formulation.

High Acyl Gellan Gum Water Concentration
1 kg 50–100 kg 1–2%
100 g 5–10 kg 1–2%
10 g 500–1000 g 1–2%

The hydrated stock solution can then be transferred into the production batch.

❓ Frequently Asked Questions (FAQ)

Can High Acyl Gellan Gum Hydrate in Cold Water?

No. While it may disperse in cold water, complete hydration typically requires heating to 85–90°C.

Can High Acyl Gellan Gum Be Added After UHT?

Generally not recommended. Hydration should occur before homogenization and UHT treatment.

Can High Acyl Gellan Gum Stabilize Proteins?

Yes. It is widely used with milk proteins, soy proteins, pea proteins and oat proteins.
