Spices, Extracts

Cinnamon (Cinnamomum verum, synonym C. zeylanicum) is a small evergreen tree 10-15 m tall, belonging to the family Lauraceae, native to Sri Lanka and Southern India. The bark is widely used as a spice. more...

The leaves are ovate-oblong in shape, 7-18 cm long. The flowers, which are arranged in panicles, have a greenish colour and a rather disagreeable odour. The fruit is a purple 1 cm berry containing a single seed.

Cinnamon is harvested by growing the tree for two years and then coppicing it. The next year a dozen or so shoots will form from the roots. These shoots are then stripped of their bark and left to dry. Only the thin (0.5 mm) inner bark is used; the outer woody portion is removed, leaving metre long cinnamon strips which curl into rolls ("quills") on drying; each dried quill comprises strips from numerous shoots packed together. These quills are then cut to 5-10 cm long pieces for sale.

The best cinnamon comes from Sri Lanka, but the tree is also grown commercially at Tellicherry in Java, Sumatra, the West Indies, Brazil, Vietnam, Madagascar, and Egypt. Sri Lanka cinnamon of fine quality is a very thin smooth bark, with a light-yellowish brown colour, a highly fragrant odour, and a peculiarly sweet, warm and pleasing aromatic taste.

Its flavour is due to an aromatic essential oil which it contains to the extent of from 0.5 to 1%. This oil is prepared by roughly pounding the bark, macerating it in sea-water, and then quickly distilling the whole. It is of a golden-yellow colour, with the characteristic odour of cinnamon and a very hot aromatic taste. The pungent taste and scent come from cinnamic aldehyde or cinnamaldehyde and, by the absorption of oxygen as it ages, it darkens in colour and develops resinous compounds. Chemical components of the essential oil include eugenol, cinnamaldehyde, beta-caryophyllene, linalool and methyl chavicol.
