The
Eggplant is a Relative of the Potato and Probably Originated
in India in Ancient Times
however, it didn’t appear in Europe until the fourteenth
century and in the Americas until the seventeenth century.
Thomas Jefferson first brought it to the United States from
France. The edible part of the plant is a large pear-shaped
fruit that is a berry. Most eggplants, also known by their
French name aubergine, are deep purple, although yellowish
white cultivars are sometimes available. The purple ones
are marketed year round in most areas. Choose fruits that
are firm, heavy, free of scars, and deeply colored (if purple).
Small, slender eggplants have smaller seeds are sweeter and
more tender, but the larger ones are more practical for dishes
in which the eggplant is peeled, and/or sliced. Eggplants
can be stored at room temperature or in the refrigerator
for a week.

Eggplant
Contains High Levels of an Antioxidant Compound that
May Protect the Body's Cells
against oxidative damage, according to studies by two
Agricultural Research Service scientists. They found
that chlorogenic acid, one of the most powerful antioxidants
produced in plant tissues, was the predominant phenolic
compound in nearly all the samples analyzed.

Scientists Get Under Eggplant's Skin
Agricultural Research Service scientists recently made
headway unlocking the secrets of Black Magic-a commercial
eggplant cultivar representative of U.S. market types.
Apparently, when horticulturists named it, they were
onto something. Turns out the variety has nearly three
times the amount of antioxidant phenolics found in other
eggplant cultivars that were studied.

Everyone Knows What an Eggplant Is...Right?
Most people have probably tasted an eggplant. You may
have been in an Italian restaurant where chefs use the
purplish fruit (like a tomato, it is botanically classified
as a fruit) in the popular dish eggplant parmesan.
But maybe the eggplant used wasn't purple. Maybe it wasn't
even teardrop shaped. Eggplants come in hundreds of shapes
and colors. But the fruit probably got its name because
some small-fruited, white-pigmented eggplant varieties
look like chicken eggs.
Griffin, Georgia, is home to USDA's eggplant collection,
which includes 770 different accessions collected from
around the world. While nontraditional ones may not be
available at most grocery stores, they are often found
in gourmet and ethnic food stores and local farmers' markets.
Flowers
of eggplant are similar to those of potato and tomato.
All three plants are solanaceous species.
Eggplant is much more popular outside the United States,
particularly in India (where the first eggplants supposedly
grew) and other Asian countries. In India, many people
eat small, round eggplants. Some enjoy eggplant cooked
and served with other vegetables as part of a medley. Others
enjoy the popular dish of eggplant curry. Different ethnicities
prefer different varieties, depending on how bitter they
like the fruit to taste.
