🥤 : Case Study – Using Gellan Gum in Clear Beverage Stabilization
📌 The Challenge: Keeping Juice Suspended in Clear Drinks
A beverage company launched a premium line of clear fruit juices with added pulp and vitamins. While the product tasted great, it faced a major formulation issue:
- ⚠️ Fruit pulp quickly settled at the bottom
- ⚠️ Cloudiness appeared after storage
- ⚠️ Conventional thickeners ruined the clarity
They needed a stabilizing system that could:
- Keep particles suspended
- Maintain brilliant clarity
- Resist heat during pasteurization
- Work with acidic pH (~3.8–4.2)
💡 The Solution: Low Dosage Gellan Gum
The R&D team turned to low-acyl gellan gum, a smart choice for fluid gel systems in clear beverages. Why?
✔️ Forms a weak, flowing gel network that holds particles in suspension
✔️ Doesn't cloud the drink — perfect optical clarity
✔️ Works at ultra-low concentrations (0.015%–0.035%)
✔️ Stable at low pH and high processing temperatures
🧪 Formulation Snapshot
| Ingredient | Usage (%) |
|---|---|
| Fruit juice base | 90–95 |
| Water | up to 100% |
| Low-acyl gellan gum | 0.025 |
| Calcium chloride | 0.01 (if needed) |
| Sugar, acid, flavor | As per formula |
- Disperse gellan gum in hot water (above 85°C)
- Mix with fruit juice base and cool to set gel matrix
- Bottle and pasteurize if needed
Result:
✅ A crystal-clear beverage with suspended pulp — no sedimentation for over 6 months.
📊 Before vs After Gellan Gum
| Property | Before Gellan Gum | After Gellan Gum |
|---|---|---|
| Suspension stability | < 2 days | > 6 months |
| Visual clarity | Cloudy | Sparkling clear |
| Pasteurization resistance | Poor | Excellent |
| Customer feedback | Mixed | 5-star reviews ⭐⭐⭐⭐⭐ |
