Coriander seeds should be uniform in size and shape, with a slightly wrinkled surface. The seeds should be round to slightly oblong and range in color from pale yellow to light brown.
The moisture content of coriander seeds should not exceed 12%. High moisture content can lead to spoilage and mold growth.
Coriander seeds should be free from foreign matter, such as stones, dirt, and other debris. The maximum allowable amount of foreign matter is typically 1.0%.
Coriander seeds should have a minimum of 95.0% sound kernels. This means that no more than 5.0% of the kernels can be damaged, broken, or diseased.
