Cardamom curing, drying and size grading
Post-harvest curing of small cardamom is critical for retaining the green colour and volatile oil that determine export grade. ICAR-IISR and Spices Board protocols specify pre-cleaning, washing in 2% sodium carbonate, then drying at 45-50 degC in flue-cured kilns or improved bhattis for 22-30 hours, achieving 8-10% moisture.
Key parameters
- Drying Temperature: 45-50 degC for 22-30 hours
- Final Moisture: 8-10% moisture content
- Grading Criteria: size (bold/small) and colour (green/yellow/brown)
- Purpose: retain green colour and volatile-oil content for export
Implementation and adoption
Cured capsules are graded by size (AGEB, AGB1, AGB2 for 8-7-6 mm bold to small) and colour for domestic and export markets, with green-saver formulations giving best price realization.
