Chelsea Sugar's Refining Process: A Non-Bone Char Approach
For those following a vegan or vegetarian diet, or simply concerned about the ethical sourcing of their food, the use of bone char in sugar refining is a significant consideration. The good news for consumers of Chelsea Sugar is that the company has confirmed it does not use this animal-based filtering process. Instead, they use a plant-based alternative to achieve the pure white colour consumers expect.
The Shift Away from Bone Char
Historically, the Chelsea Sugar refinery did use bone char but discontinued this around the year 2000. The building that once housed the bone char filtration system is now a historical landmark. This change reflects a move towards more transparent and ethically conscious production.
The Modern Chelsea Sugar Refining Process
Chelsea Sugar uses modern, non-animal-based techniques to refine raw sugar sourced from overseas cane mills. The process includes washing, dissolving, and clarification using milk of lime and carbon dioxide. For decolourisation, activated carbon sourced from coal is used to remove colour, replacing the traditional bone char. The sugar is then sterilised using UV light, crystallised by boiling in a vacuum, dried, and packed.
Comparison: Chelsea Sugar vs. Traditional Bone Char Refining
| Feature | Chelsea Sugar Refining Process | Traditional Bone Char Refining |
|---|---|---|
| Clarification Agent | Activated carbon sourced from coal | Char produced from animal bones |
| Vegan Status | Vegan-friendly (for most products) | Not vegan-friendly |
| Sterilisation | Ultra-violet (UV) light | May not include UV sterilisation |
| Process | Entirely animal-product free | Relies on an animal-derived product |
| Origin | Modern process, used since approx. 2000 | Historical practice, largely phased out by progressive manufacturers |
Vegan and Vegetarian Considerations
Using activated carbon makes almost all Chelsea sugars and syrups suitable for vegans and vegetarians. One exception is the Honey Maple Flavoured Syrup. Checking ingredients lists for flavoured syrups is always recommended.
Kosher and Halal Certification
Many Chelsea sugar products hold Kosher and Halal certifications.

Conclusion
Chelsea Sugar does not use bone char, having discontinued the practice around 2000 in favour of coal-based activated carbon. This makes most of its products suitable for vegans and vegetarians, with the exception of its honey-containing syrup.
