What ISO 3632 is used for
ISO 3632 provides a standard framework for testing dried saffron. It allows a buyer and seller to refer to measured characteristics rather than relying only on colour, aroma or a commercial grade name.
A laboratory report applies to the tested sample. Buyers should match the report to the offered lot and agree sampling, validity and acceptance terms before shipment.
Crocin, picrocrocin and safranal
Crocin is associated with saffron's colouring strength. Picrocrocin is associated with its characteristic bitter taste, while safranal is associated with aroma. These measurements are interpreted together with other checks in the applicable test report.
A higher commercial grade is not a substitute for measured results. Two visually similar lots can still require laboratory comparison.
Physical inspection still matters
Laboratory values should be considered alongside the physical condition of the shipment.
- Uniformity and proportion of red stigma to yellow style
- Evidence of foreign matter or broken material
- Packing integrity and protection from moisture and light
- Lot identification that connects samples, documents and cartons

Frequently asked questions
Does ISO 3632 identify the saffron grade?
ISO 3632 provides test methods and quality classification. Commercial names such as Super Negin or Sargol also describe physical presentation, so buyers should specify both the grade and required test results.
What does crocin measure?
Crocin is associated with saffron colouring strength and is one of the key values commonly reviewed on an ISO 3632 laboratory report.
Can a buyer request laboratory analysis?
Yes. Goodarzi Trading lists ISO 3632 laboratory analysis on request for saffron consignments.
