Fruit



The dry fruits are known as coriander or coriandi seeds. In India they are called dhania. The word coriander in food preparation may refer solely to these seeds (as a spice), rather than to the plant itself. The seeds have a lemony citrus flavour when crushed, due to terpene

. It is described as warm, nutty, spicy, and orange-flavored.

The variety vulgare or macrocarpum has a fruit diameter of 3–5 mm while var. microcarpum fruits have a diameter of 1.5–3 mm. Large fruited types are grown mainly by tropical and subtropical countries, e.g. Morocco, India and Australia and contain a low volatile oil content (0.1-0.4%). They are used extensively for grinding and blending purposes in the spice trade. Types with smaller fruit are produced in temperate regions and usually have a volatile oil content of around 0.4-1.8%, and are therefore highly valued as a raw material for the preparation of essential oil.

It is commonly found both as whole dried seeds and in ground form. Seeds can be roasted or heated on a dry pan briefly before grinding to enhance and alter the aroma. Ground coriander seed loses flavor quickly in storage and is best ground fresh.

Health effects and medicinal uses


Coriander, like many spices, contains antioxidants, which can delay or prevent the spoilage of food seasoned with this spice. A study found both the leaves and seed to contain antioxidants, but the leaves were found to have a stronger effect.

Chemicals derived from coriander leaves were found to have antibacterial activity against Salmonella choleraesuis, and this activity was found to be caused in part by these chemicals acting as nonionic surfactants.
