Ceylon cinnamon (Cinnamomum verum) commands a significant price premium over Cassia (Cinnamomum aromaticum) and is specifically protected under Sri Lanka's GI (Geographical Indication) certification. Two critical quality parameters drive export compliance: moisture content (maximum 14% for EU/US markets) and cinnamaldehyde concentration (the primary bioactive marker distinguishing Ceylon from Cassia and determining flavour intensity). Both are currently measured by slow laboratory methods.

## What We've Established

### NIR Feasibility - Cinnamaldehyde

Cinnamaldehyde's conjugated aldehyde structure produces characteristic NIR absorption features in the C=O and C–H stretch combination regions. Published NIR studies on cinnamon authentication using these features demonstrate classification accuracy above 95% for Ceylon vs. Cassia discrimination - a commercially critical capability for the Sri Lankan export sector.

### Authentication Opportunity

The Sri Lanka Export Development Board has documented repeated cases of Ceylon cinnamon being adulterated or substituted with Cassia in international markets. A rapid NIR-based authentication tool addresses a verified market need with direct GI certification relevance.

## Technical Approach

Proposed dual-parameter model targeting moisture and cinnamaldehyde simultaneously from a single NIR scan. Reference methods: ISO 6468 for moisture, steam distillation + GC analysis for cinnamaldehyde. Requires authenticated Ceylon and Cassia samples across multiple grades (International Grade 0–4) to build both a quantification model and a classification boundary for adulteration detection.

## Where We Stand

Initial outreach to industry partners and the Ceylon Cinnamon Exporters Association was completed. Response is pending. No dataset work has commenced.

## Next Steps

- Confirm partner engagement and establish sample collection protocol
- Source authenticated reference samples from certified GI cinnamon producers
- Build authentication dataset spanning both Ceylon and Cassia at multiple grades
