Poppy
(Papaver somniferum L.)
Poppy is an ancient cultigen; it is mentioned in the Ilias, an epic
ascribed to the legendary Greek poet Homeros. The Ilias is, together
with the contemporary Odysseia, by far the oldest European poetry
and was probably fixed from oral tradition in the 8.th century,
but it tells of events that might have happened five hundred years
ago. It gives a unique insight in the thought and life of the ending
Bronze Age, for it describes or at least mentions much of everyday
life.
The ancients valued poppy for the oil obtained from its seeds; yet
the narcotic and analgetic power of opium was well known to Greek
medicine. Opium as a drug is a comparatively young development in
Europe.
Today, poppy oil is an unusual speciality and is produced only in
small quantities; most common is a cold-pressed quality suited for
salads (see sesame about vegetable oils in general). Poppy farmers
in Western Europe are faced by numerous legal restrictions designed
to prevent the production of opium. Yet, in Western European climate,
poppy plants do not develop much alkaloids, and any opium produced
there would be of comparably minor quality.
In Europe, poppy seeds are mostly used for confectionary, similar
to the use of sesame and nigella in the Near East. Stuffings based
on poppy are sometimes found in croissants and the Austrian desserts
known as strudel. Most of these recipes originated in Bohemia (today's
Czech Republic), whence they came to Austria in the times of the
Austro-Hungarian Empire. Another great example for this sweet and
high-calorie cooking tradition are Germknödel, steamed yeast
dumplings stuffed with a very concentrated kind of plum jam (Powidl)
and served with powdered sugar, ground poppy seeds and molten butter.
Yet in Asia poppy is not unknown for cooking, either. Ground poppy
seeds are a common thickening agent in the moghul cooking style
of Northern India; a special creme-white variety was bred for light
sauces. Poppy's nutty taste is loved by the Japanese and used for
the subtly flavoured dishes typical for Japan. The Japanese spice
mixture shichimi togarashi contains poppy seeds.
Used plant part
Ripe seeds. The drug opium is prepared from the unripe capsules.
Plant family
Papaveraceae (poppy family).
Sensoric quality
Nutty and pleasant.
Main constituents
Poppy seeds contain 40 to 50% of fatty oil, which is obtained by
cold pressing in yields of only 12 to 18%. It is rich in unsaturated
fatty acids (iodine index is 133 to 144): 60% linoleic acid, 30%
oleic acid, 3% linolenic acid (triply unsaturated; essential for
human nutrition) and less than 10% saturated fats. Among the volatile
components of poppy seeds, aliphatic hydrocarbons and aldehydes
have been reported. 2-Pentylfuran is a key aroma compound.
Opium is the dried latex from unripe seed capsules; each capsule
yields about 20 to 50 mg. Besides wax, resin, proteins and sugars,
it contains approximately 20% of alkaloids, of which morphine (morphin,
typically, 12%) is the most important. Opium for smoking (chandu)
is roasted over fire and fermented, which reduces the alkaloid content
to about one quarter and leads to the development of a typical flavour.
Opium contains two family of alkaloids. Phenanthrene-type alkaloids
include morphine (7 to 23%), codeine (max. 3%), thebaine (max. 3%,
typically much lower) and the synthetic heroin. Benzylisochinoline-type
alkaloids are more common in the plant kingdom; in opium, they are
represented by narcotine (=noscapine, up to 12%), papaverine (max.
1.5%) and narceine (0.2%). Most of these have their special field
of application in modern medicine. Official opium production is
2000 tons per year, mostly by India and Turkey.
The alkaloid content of poppy seeds is low (50 ppm) and cannot have
any pharmaceutical effect. It is, however, high enough that morphine
can be detected in the urine after heavy poppy seed consume, which
might make for an unpleasant surprise in drug tests.
Origin
Poppy probably stems from West Asia, but it is cultivated in Europe
since the neolithic era; it is probably one of the earliest plants
cultivated by men in that region. Turkey is one of the main producers
and exporters of Blue, White and Yellow Poppy Seeds.
