Cardamom

Chemical properties

This perennial bears violet-striped, white flowers and aromatic, green fruits on erect or trailing racemes. The small variety of cardamom (α-minor) cultivated in Malabar is the most valuable variety. This variety has been almost entirely replaced, in the last 50 years, by the larger variety, β-major. The plant grows more than 2 m tall and exhibits a long rhizome from which the fruitbearing stalks emerge. The fruits (husks) containing the seed are harvested prior to ripening, which is completed by exposing them to sunlight. The seeds are subsequently sorted into several commercial qualities based on color, size and origin (Malabar, Cylone, Mysore). Cardamom has a warm, spicy, aromatic odor that is somewhat pungent and faintly bitter at high concentrations.
