Prune
A prune is any
of various plum cultivars, mostly Prunus domestica or European Plum, sold as
fresh or dried fruit. The dried fruit is also referred to
as a dried plum. In general, fresh prunes are freestone cultivars (the pit is easy to remove),
whereas most other plums grown for fresh consumption are clingstone (the pit is
more difficult to remove).
Production
More than 1,000
cultivars of plums are grown for drying. The main
cultivar grown in the U.S. is the Improved French prune. Other varieties
include Sutter, Tulare Giant, Moyer, Imperial, Italian, and Greengage. Fresh prunes reach the market earlier
than fresh plums and are usually smaller in size.
Branding
Due to popular
perception (in the U.S.) of prunes being used only for relief of constipation,
and being the subject of related joking, many of today's distributors have
stopped using the word "prune" on packaging labels. Their preference
is to state "dried plums".[1]
Uses
Prunes are used
in cooking both sweet and savory dishes. Stewed prunes, a compote, are a dessert. Prunes are a frequent
ingredient in North African
tagines. Perhaps the best-known gastronomic
prunes are those of Agen (pruneaux d'Agen). Prunes are used
frequently in Tzimmes, a traditional Jewish dish in which the principal ingredient is
diced or sliced carrots; in the Nordic prune kisel,
eaten with rice pudding in the
Christmas dinner; and in the traditional Norwegian dessert fruit soup. Prunes have also been included in
other holiday dishes, such as stuffing, cake,
and to make sugar plums. Prune
filled Danish pastries are popular primarily in New York and other parts of the
U.S. East Coast. Prune ice cream is popular in the Dominican Republic. Prunes
are also used to make juice.
Health effects
Benefits
Prunes and
their juice contain mild laxatives including phenolic
compounds (mainly as neochlorogenic acids
and chlorogenic acids)
and sorbitol.[2] Prunes also contain dietary fiber (about 7%, or 0.07 g
per gram of prune). Prunes and prune juice are thus common home remedies for constipation. Prunes also have a high antioxidant
content.[3]
Disadvantages
Dried prunes
have been found to contain high doses of a chemical called acrylamide which is a known neurotoxin and a
carcinogen.[4] Acrylamide does not occur naturally in
foods but is formed during the cooking process at temperatures > 100 °C.
Although the common drying mechanism of prunes does not involve high
temperatures, formation of high amount of acrylamide has been reported in dried
prunes as well as pears.
However,
although acrylamide has known toxic effects on the nervous system and on
fertility, a June 2002 report by the Food and Agriculture Organization of the
United Nations and the World Health Organization concluded the intake level
required to observe neuropathy (0.5 mg/kg body weight/day) was 500 times
higher than the average dietary intake of acrylamide (1 μg/kg body weight/day).
For effects on fertility, the level is 2,000 times higher than the average
intake.[5] From this, they concluded acrylamide
levels in food were safe in terms of neuropathy, but raised concerns over human
carcinogenicity based on known carcinogenicity in laboratory animals.[5]
