Origin and history

Coriander grows wild over a wide area of Western Asia and Southern Europe, prompting the comment: "It is hard to define exactly where this plant is wild and where it only recently established itself." Recent works suggested that coriander accessions found in the wild in Israel and Portugal might represent the ancestor of the cultivated coriander. Article number 138. They have low germination rates and a small vegetative appearance. The accession found in Israel has an extremely hard fruit coat. Fifteen desiccated

Uses

The fresh leaves and the dried seeds are the parts most commonly used in cooking, but all parts of the plant are edible and the roots are an important element of Thai cooking. Coriander is used in cuisines throughout the world.

Leaves

The leaves are variously referred to as coriander leaves, fresh coriander, Chinese parsley, or (in the US and commercially in Canada) cilantro. The fresh leaves are an ingredient in many foods, such as

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 around 0.4-1.8%, so are highly valued as a raw material for the preparation of essential oil.

s and terpenes, including linalool as the major constituent accounting for the aroma and flavor of coriander. Different people may perceive the taste of coriander leaves differently. Those who enjoy it say it has a refreshing, lemony or lime-like flavor, while those who dislike it have a strong aversion to its pungent taste and smell, characterizing it as soapy or rotten. Studies also show variations in preference among different ethnic groups: 21% of East Asians, 17% of Caucasians, and 14% of people of African descent expressed a dislike for coriander, but among the groups where coriander is popular in their cuisine, only 7% of South Asians, 4% of Hispanics, and 3% of Middle Eastern subjects expressed a dislike. About 80% of identical twins shared the same preference for the herb, but fraternal twins agreed only about half the time, strongly suggesting a genetic component to the preference. In a genetic survey of nearly 30,000 people, two genetic variants linked to perception of coriander have been found, the most common of which is a gene involved in sensing smells. The gene '' OR6A2'' lies within a cluster of olfactory-receptor genes, and encodes a receptor that is highly sensitive to aldehyde chemicals. Flavor chemists have found that the coriander aroma is created by a half-dozen or so substances, and most of these are aldehydes. Those who dislike the taste are sensitive to the offending unsaturated aldehydes and at the same time may be unable to detect the aromatic chemicals that others find pleasant. Association between its taste and several other genes, including a bitter-taste receptor, have also been found.

Allergy

Some people are allergic to coriander leaves or seeds, having symptoms similar to those of other food allergies.
