Stabilizer Blending

Commercial stabilizer blends are convenient but opaque—you don’t know exactly what’s in them or in what proportions. Building your own blends gives you control, understanding, and the ability to optimize for specific applications.

Why Blend Multiple Stabilizers?

Single stabilizers have limitations. Blending creates synergies:

Single Stabilizer	Limitation	Solved By Adding
LBG alone	No melt resistance	Lambda carrageenan
Guar alone	Can be gummy	LBG (smoother character)
Xanthan alone	Slimy texture	LBG (creamier)
Lambda carrageenan alone	Weak thickening	LBG or guar

Synergy Principles

LBG + Lambda Carrageenan

The foundational synergy for frozen desserts:

• Lambda carrageenan increases LBG’s effectiveness
• Combined creaminess greater than either alone
• Improved melt resistance
• Better ice recrystallization inhibition

Typical ratio: 5:1 (LBG:lambda carrageenan)

LBG + Xanthan

Creates enhanced viscosity:

• Xanthan provides immediate thickening
• LBG provides long-term stability
• Combined viscosity exceeds sum of parts

Typical ratio: 3:1 to 5:1 (LBG:xanthan)

Galactomannans Together (LBG + Guar + Tara)

Similar gums complement each other:

• LBG: Best creaminess
• Guar: Economic, cold-dispersible
• Tara: Middle ground, good synergy with carrageenan

Typical approach: LBG as primary, guar and/or tara as secondary

Building a Blend: Step by Step

Define Application

What are you stabilizing?

• Custard base (eggs present)
• Eggless base (no natural emulsification)
• Sorbet (no fat)
• Special application (low-fat, vegan, etc.)

Select Primary Stabilizer

Usually LBG or tara gum. This forms 40–60% of blend.

Add Secondary Stabilizers

Choose 1–2 secondary stabilizers that complement primary. Usually 20–40% of blend.

Include Synergist

Add lambda carrageenan for synergy. Usually 3–10% of blend.

Add Carrier

Include dextrose or maltodextrin to aid dispersion. Usually 10–20% of blend.

Test and Adjust

Make test batch. Evaluate texture. Adjust ratios as needed.

Blend Formulas by Application

Standard Gelato (Custard Base)

Component	Percentage	Function
LBG	50%	Primary stabilization, creaminess
Guar	30%	Supporting thickening
Lambda carrageenan	10%	Synergy, melt resistance
Dextrose	10%	Carrier, dispersion aid

Total dose: 0.25–0.35% of base weight

---

Eggless Base

Without egg proteins, stronger stabilization needed:

Component	Percentage	Function
LBG	40%	Primary
Guar	25%	Thickening
Lambda carrageenan	10%	Creaminess
Xanthan	5%	Emulsion stability
Dextrose	20%	Carrier

Total dose: 0.35–0.45% of base weight

---

Sorbet

No fat means stabilizers do all structural work:

Component	Percentage	Function
LBG	40%	Primary
Tara	25%	Synergy with carrageenan
Guar	20%	Economy, thickening
Lambda carrageenan	5%	Melt resistance
Dextrose	10%	Carrier

Total dose: 0.40–0.50% of base weight

---

Low-Fat Base

Reduced fat requires enhanced stabilization:

Component	Percentage	Function
LBG	40%	Primary
Guar	20%	Thickening
Lambda carrageenan	15%	Enhanced creaminess
Xanthan	5%	Body
Dextrose	20%	Carrier

Total dose: 0.40–0.50% of base weight

---

Vegan Base

All plant-derived components:

Component	Percentage	Function
LBG	45%	Primary
Tara	25%	Secondary
Guar	15%	Thickening
Lambda carrageenan	5%	Synergy
Dextrose	10%	Carrier

Total dose: 0.40–0.50% of base weight

All components are naturally vegan.

Calculating Blend Amounts

For Pre-Made Blend

If you’ve created 100g of blend:

Blend amount needed = base weight × target percentage

Example: 0.35% stabilization of 1000g base

Blend needed = 1000g × 0.0035 = 3.5g

For Individual Components

Calculate each component separately:

Example: 0.30% total stabilization, blend is 50% LBG, 30% guar, 10% lambda, 10% carrier

For 1000g base:

• LBG: 1000 × 0.003 × 0.50 = 1.5g
• Guar: 1000 × 0.003 × 0.30 = 0.9g
• Lambda: 1000 × 0.003 × 0.10 = 0.3g
• Dextrose: 1000 × 0.003 × 0.10 = 0.3g

Making Blend in Advance

For convenience, pre-mix larger quantities:

Calculate Quantities

For 100g blend at your desired ratios.

Weigh Carefully

Use precision scale (0.01g for small components).

Blend Thoroughly

Whisk together in dry bowl for 2–3 minutes. Pass through fine sieve.

Store

Keep in airtight container away from moisture. Label with date and ratios.

Use

Weigh needed amount per batch. Disperse as usual.

Shelf life: 6–12 months in dry, sealed container.

Adjusting for Specific Issues

If Product Is Too Icy

• Increase total stabilizer dose by 20%
• Increase LBG proportion
• Ensure proper hydration temperature

If Product Is Gummy

• Reduce total dose by 20%
• Reduce guar proportion specifically
• Consider replacing guar with more LBG

If Meltdown Is Too Fast

• Increase lambda carrageenan to 15% of blend
• Slightly increase total dose

If Texture Is Slimy

• Reduce xanthan if present
• Increase LBG proportion
• Reduce total dose

Commercial Blend Comparison

Commercial Blend	Approximate Composition	Dose
Cremodan 30	LBG, guar, carrageenan, mono/diglycerides	0.4–0.6%
Perfect Gelato	LBG-based with carrageenan	0.3–0.5%
Perfect Sorbet	Enhanced for no-fat applications	0.5%
Versawhip	Modified soy protein (for foams)	0.5–1.0%

Note

Commercial blends often include emulsifiers (mono/diglycerides) which home blends don’t. For eggless bases, consider adding soy or sunflower lecithin (0.1–0.2%) to your blend.

Testing Protocol

When developing a new blend:

1. Make small test batch (500g base)
2. Evaluate immediately after churn:
   • Texture
   • Creaminess
   • Body
3. Evaluate after 24 hours:
   • Scoopability
   • Ice crystal formation
4. Evaluate after 1 week:
   • Texture degradation
   • Iciness development
5. Adjust and repeat

Keep detailed notes on each test for comparison.
