Can HA and LA Gellan Gum Be Used Together?

Quick Overview

Yes, High Acyl (HA) and Low Acyl (LA) gellan gum can be used together in some applications.

Although HA and LA have different functional characteristics, combining them can help create a balance between:

✓ softness
✓ strength
✓ elasticity
✓ suspension ability
✓ texture control

A mixed HA/LA system is often considered when a single gellan gum type cannot provide all required properties.

Why Combine HA and LA Gellan Gum?

HA and LA provide different advantages.

HA Gellan Gum

Generally provides:

* soft texture
* elasticity
* smooth mouthfeel
* flexible structure

---

LA Gellan Gum

Generally provides:

* stronger gel network
* higher firmness
* better transparency
* stronger mineral response

---

By combining both, developers can adjust the final texture.

The goal is usually not to maximize gel strength, but to achieve the desired product performance.

---

Possible Benefits of HA + LA Combination

1. Balance Softness and Strength

Pure LA may create a gel that is:

* too firm
* too brittle

Adding HA may help create:

* softer texture
* improved flexibility

---

2. Improve Suspension Performance

Some beverage systems require:

* particle stability
* good mouthfeel

A mixed system may provide stronger suspension while avoiding excessive viscosity.

---

3. Adjust Texture

By changing the HA/LA ratio, developers can explore different textures:

More HA:

→ softer
→ more elastic

More LA:

→ stronger
→ firmer

Basic Reference Formula

For 100 kg System

| Ingredient | Amount |
| -------------- | --------------------------: |
| Water | Balance |
| Sugar / solids | According to product |
| HA Gellan Gum | 50–300 g |
| LA Gellan Gum | 50–300 g |
| Calcium source | Adjust according to formula |

Example Starting Ratios

Trial A — Softer Texture

HA : LA

3 : 1

Example:

* HA: 300 g
* LA: 100 g

Expected:

* softer
* more elastic

---

Trial B — Balanced Structure

HA : LA

1 : 1

Example:

* HA: 200 g
* LA: 200 g

Expected:

* balanced texture
* moderate strength

---

Trial C — Stronger Structure

HA : LA

1 : 3

Example:

* HA: 100 g
* LA: 300 g

Expected:

* stronger
* firmer gel

---

Suggested Processing Method

Step 1 — Dry Mixing

Premix:

* HA gellan gum
* LA gellan gum
* sugar

before hydration.

This improves dispersion.

---

Step 2 — Hydration

Hydrate at:

85–90°C

Ensure both components are fully hydrated.

---

Step 3 — Mineral Adjustment

If LA content is high, pay attention to:

* calcium
* magnesium
* water hardness

Mineral balance can strongly affect the final texture.

---

Step 4 — Cooling and Evaluation

Test:

* gel strength
* elasticity
* suspension
* storage stability

---

Example Applications

Plant-Based Beverage

Possible goal:

* smooth mouthfeel
* stable suspension

A higher HA ratio may be preferred.

---

Fruit Suspension Beverage

Possible goal:

* particle stability
* clear appearance

A higher LA ratio may be considered.

---

Soft Gel Dessert

Possible goal:

* elasticity
* pleasant texture

A balanced HA/LA ratio may be explored.

---

Common Problems & Solutions

Problem 1: Mixed System Becomes Too Strong

Possible causes:

* too much LA
* excessive calcium

Solutions:

* increase HA ratio
* reduce mineral level

---

Problem 2: Suspension Is Still Not Stable

Possible causes:

* insufficient total dosage
* unsuitable particle characteristics

Solutions:

* optimize total gellan gum level
* adjust particle size

---

Problem 3: Results Change Between Batches

Possible causes:

* different water minerals
* ingredient variation
* processing differences

Solutions:

Control:

* water quality
* calcium level
* heating process

---

Practical Starting Formula

For a first HA/LA combination trial:

100 kg system

*

200 g HA gellan gum

*

100 g LA gellan gum

*

Controlled calcium addition

*

Hydration at 85–90°C

is a reasonable starting point.

The final ratio should be optimized according to:

* target texture
* application type
* ingredient interactions
* processing conditions

---

Final Summary

HA and LA gellan gum can be combined when a product requires properties from both systems.

In simple terms:

More HA → softer and more elastic

More LA → stronger and firmer

A carefully designed HA/LA combination can provide more flexibility for product developers.
