Gellan Gum Formula for Chewing Gum

Quick Overview

Chewing gum is a complex confectionery system containing:

* gum base
* sweeteners
* flavors
* plasticizers
* moisture-control ingredients

The main formulation goals are:

✓ pleasant chewing texture
✓ controlled softness
✓ stable moisture content
✓ long-lasting flavor release

Gellan gum can be considered as a functional hydrocolloid in some chewing gum systems to help modify texture and moisture behavior.

Basic Reference Formula

For 100 kg finished chewing gum:

| Ingredient | Amount |
| ------------------------- | ----------: |
| Gum base | 20–35 kg |
| Sugar or sweetener | 40–70 kg |
| Syrup / humectant | 5–20 kg |
| Flavor | 0.5–2 kg |
| High Acyl Gellan Gum (HA) | 100–300 g |
| Other ingredients | as required |

Recommended Starting Dosage

Gellan Gum:

0.10–0.30%

Equivalent to:

100–300 g gellan gum per 100 kg product

Why Use Gellan Gum in Chewing Gum?

Chewing gum texture depends on the balance between:

* elasticity
* softness
* moisture
* chew resistance

A hydrocolloid system may help improve:

* texture consistency
* moisture retention
* product stability

The objective is not to create a gel.

The objective is controlled chewing performance.

HA or LA Gellan Gum Selection

High Acyl Gellan Gum (HA)

May be considered when softer texture is required.

Potential benefits:

✓ flexible texture
✓ smoother chewing experience
✓ improved moisture control

---

Low Acyl Gellan Gum (LA)

Creates stronger gel structures.

It is generally less suitable when a soft chewing texture is required.

Selection depends on the desired product characteristics.

---

Suggested Processing Method

Step 1 — Dry Blending

Premix gellan gum with powdered ingredients.

This improves:

* dispersion
* processing consistency

---

Step 2 — Gum Base Mixing

Combine:

* gum base
* sweeteners
* syrup ingredients

under controlled temperature.

---

Step 3 — Add Hydrocolloid System

Add gellan gum gradually during mixing.

Ensure uniform distribution.

---

Step 4 — Cooling and Forming

Cool the mixture.

Shape and package according to product requirements.

---

Recommended Trial Design

A small dosage test is recommended.

| Trial | Gellan Gum |
| ----- | ---------: |
| A | 0.10% |
| B | 0.15% |
| C | 0.20% |
| D | 0.30% |

Evaluate:

* chewing texture
* softness
* moisture stability
* shelf-life performance

Common Problems & Solutions

Problem 1: Gum Becomes Too Hard

Possible causes:

* excessive hydrocolloid level
* low moisture content
* unsuitable gum base ratio

Solution:

Reduce dosage gradually.

---

Problem 2: Texture Changes During Storage

Check:

* humidity conditions
* packaging
* sweetener system
* moisture migration

Hydrocolloid selection is only one part of the formulation.

---

Practical Starting Formula

For a first chewing gum trial:

100 kg chewing gum

*

100–300 g gellan gum

is a reasonable starting range.

The final formula should be optimized according to:

* gum base type
* sweetener system
* moisture level
* desired chewing texture
* storage conditions

This formula is intended for product development trials only. Commercial production should always be validated with actual ingredients and processing conditions.
