technical & quality
Thornton Sugar has supplied the UK food industry since 1959, combining decades of ingredient expertise with modern technical, quality, and supply chain assurance standards.
We support our customers with:
- + Technical product guidance
- + Specification management
- + Supply chain traceability
- + Regulatory compliance support
- + Audit and documentation assistance
We do not simply supply sugar, we provide ingredient expertise and technical partnership.
Are sulphites or additives such as E220 – E228 used in your sugar?
No. The sugar supplied by Thornton Sugar Ltd is not manufactured using added sulphites (E220), sulphur dioxide, preservatives, or artificial E-number additives during the refining process.
Some product specifications may declare:
Sulphites: <10 ppm, typically resulting 4-6ppm
This does not mean sulphites have been intentionally added.
This declaration exists because trace sulphur compounds may naturally occur during:
Agricultural cultivation
Extraction and evaporation
Crystallisation processes
Laboratory analytical testing
Therefore:
No sulphites are intentionally added
No E220 or any other E is dosed into production
No preservative additives are used
This declaration reflects naturally occurring trace background levels or analytical detection capability.
Does sugar contain allergens?
Pure sugar is not classified as an allergen under UK food legislation.
However, Thornton maintains transparent technical declarations where analytical traces may require disclosure in accordance with customer or legislative requirements.
Is your sugar vegan, vegetarian, Halal or Kosher suitable?
Most products supplied by Thornton Sugar are naturally suitable for:
Vegan
Vegetarian
Halal
Kosher
Product-specific certifications and declarations are available upon request.
Why can sugar vary slightly in colour?
Sugar is a natural agricultural product, and minor variation may occur due to:
Seasonal crop differences
Natural mineral content
Crystal size variation
Processing conditions
These natural variations do not affect product safety, quality, or functionality.
Why can sugar harden or clump?
Sugar is naturally hygroscopic, meaning it absorbs moisture from the surrounding environment. To maintain product quality:
Store in dry conditions
Avoid temperature fluctuation
Keep packaging sealed
Follow FIFO stock rotation
Clumping does not indicate spoilage or food safety risk.
