Coriander processing
Practical Action
The typical aroma and flavour of coriander seed is not fully developed until it is completely dry.
Usually the whole plants are spread out in the sun to dry. They are left to wither for two days
until the moisture content is about 18%. They are then threshed to remove the seeds which are
further dried to a final moisture content of 9%. The second drying stage should be in the shade
to prevent over-heating of the seeds. The drying time depends on the climate.
In some countries artificial dryers are used to dry the seed. It is important to ensure that the
temperature of drying ovens does not exceed 100°C as this reduces the levels of volatile oils.
The clean seed should be stored in bags or closed containers.
Essential oil extraction
The ground seeds can be used for the extraction of essential oils. The seed is ground
immediately prior to distillation to increase the yield of oil and reduce the distillation time. The
essential oil content varies from 0.1-1.5% and contains a range of different essential oils. For
more information on how to distil essential oils, see the Practical Action Technical Brief.
