Sweet chestnuts are edible nuts which grow on trees of the genus Castanea in the beech
family (Fagaceae). Chestnuts are native to the Black Sea area.
They have an spiky, external husk (cupule) which spontaneously breaks open when
ripe to reveal the actual fruit. The outer husk may contain 1 - 3 fruits. The fruit consists
of the light colored nut kernel, a thin skin and a red-brown to brown pericarp. The base
of the nut has a light colored spot, also known as the "navel".
Chestnuts are of a round to oval shape. Their flavor may be described as nutty. Boiling
or roasting imparts a still stronger aroma to chestnuts. Cooking also makes it easy to
remove the skin and shell from the nut kernel.
The nut kernel predominantly consists of starch, protein, minerals and chestnut oil. For
a nut, its vitamin C content is relatively high.
The oil content of chestnuts is 1 - 2% (chestnut oil).
There is a very large number of different varieties of chestnuts, just one of which is the
"keeping" chestnut, which remains on the tree longer than normal chestnuts and must
be picked by hand.
Quality / Duration of storage
Chestnuts exhibiting mold growth on acceptance of a consignment must be rejected. If,
on unloading, they exhibit mold growth, they should not be placed in full sunshine as
this does not delay decomposition,
