Worried if sucralose can handle tough food processing? Need a sweetener that lasts? Let's quickly see how sucralose performs under stress.

Sucralose is exceptionally stable. It handles high heat (pasteurization/UHT), light, pressure, and freezing, maintaining its sweetness and integrity in various harsh food production conditions.

At FINETECH, ingredient stability is key. Clients need reliable sweeteners like sucralose that don't break down during processing. Let's quickly review its toughness.

Can Sucralose Withstand Pasteurization or UHT Processing?

Subjecting your products to high heat like pasteurization or UHT? Wondering if sucralose will lose its sweetness? Let's check its heat tolerance.

Yes, sucralose is highly heat stable. It remains unchanged and retains its sweetness through common heat treatments like pasteurization (e.g., 72°C for 15 sec) and UHT (Ultra-High Temperature, e.g., 135-150°C for a few sec).

Sucralose's strong chemical structure (C-Cl bonds) resists breakdown at high food processing temperatures.

• Pasteurization (e.g., HTST for milk): No significant loss of sucralose or sweetness.
• UHT Processing¹ (for shelf-stable products): Withstands these much higher temperatures (135-150°C) without degradation.
• Baking/Cooking: Retains sweetness well under normal baking conditions (e.g., 180-200°C).

Unlike some sweeteners (e.g., aspartame), sucralose is a reliable choice for heat-treated products, ensuring consistent taste.

Does Light Exposure Degrade Sucralose in Transparent Packaging?

Using clear bottles or see-through packaging for your products? Will light spoil sucralose's sweetness? Let's see how it handles light.

No, sucralose is generally very stable to light. In clear packaging under normal retail or storage lighting, it does not significantly degrade or lose sweetness.

Sucralose's robust molecular structure² resists breakdown from typical retail lighting (fluorescent, LED) or indirect sunlight. Studies show no significant sweetness loss or harmful byproduct formation in foods stored in transparent packaging. While extreme, direct UV might eventually affect any organic compound, normal food storage conditions are fine. This allows manufacturers to use attractive clear packaging without worrying about sweetener degradation affecting taste or shelf life.

How Does High-Pressure Processing Affect Sucralose Stability?

Using High-Pressure Processing (HPP) for your products? Does this non-thermal method harm sucralose? Let's check its stability under pressure.

Sucralose remains stable and sweet under typical HPP conditions (up to 600 MPa). The intense pressure itself does not significantly degrade the sucralose molecule.

HPP is a non-thermal pasteurization³ method using intense pressure. Sucralose's strong chemical bonds are resistant to these physical forces. It doesn't break down or lose sweetness. This makes sucralose compatible with HPP, allowing manufacturers to use this technology for fresher-tasting products without sweetener concerns. Its stability is similar to other small-molecule sweeteners under HPP.

Does Sucralose Interfere with Food Colorants or Flavors?

Using specific colors or flavors with sucralose? Worried about bad interactions? Let's see if sucralose plays well with others.

No, sucralose is generally non-reactive and does not interfere with common food colorants or flavor compounds. It typically allows the true character of added colors and flavors to come through without alteration.

Sucralose is chemically inert in most food systems.

• No Maillard Reaction⁴: It doesn't brown with amino acids.
• Colorants: Compatible with both artificial and natural colors, not causing fading beyond what the colorant itself might experience.
• Flavors: Has a clean, sugar-like taste with minimal aftertaste, so it doesn't distort or mask delicate flavors. Sweetness can even enhance perception of some flavors.

It allows formulators to achieve desired sensory profiles without unexpected changes from the sweetener.

How Does Freezing Impact Sucralose in Frozen Desserts?

Making frozen treats like ice cream? Will sucralose degrade or change when frozen? Let's look at its performance in the cold.

Sucralose is very stable during freezing and frozen storage. It doesn't degrade, lose sweetness, or negatively affect texture in frozen desserts during freeze/thaw cycles.

Sucralose handles freezing well.

• Low Temperatures: Chemically stable at typical freezer temperatures (-18°C / 0°F).
• Freezing Point: Contributes to freezing point depression like other solutes, which can benefit texture in small ways, but bulking agents are usually more important for this in low-sugar items.
• Freeze/Thaw Cycles⁵: Stable through temperature fluctuations, maintaining sweetness and quality.
• Ingredient Compatibility: Works well with dairy, fats, stabilizers, flavors, and bulking agents in frozen desserts.

Its stability makes it a reliable sweetener for high-quality, sugar-free or reduced-sugar frozen products.

Frozen Application Stability:

Conclusion

Sucralose is exceptionally stable in harsh production environments—heat, light, pressure, and freezing—and compatible with other ingredients. This makes it a highly reliable, versatile sweetener.
