Berry

Several types of "berries" from the market.

The term berry, in common parlance and in cuisine, refers generically to any small, edible fruit with multiple seeds. Aggregate fruits such as the blackberry, the raspberry, and the boysenberry are also berries in this sense, but not the botanical.

These fruits tend to be small, sweet, juicy, and of a bright color contrasting with their background to make them more attractive to animals that eat them, thus dispersing the seeds of the plant.

As berry colors derive from natural pigments synthesized by the plant, a special field of health research has focused on the anti-disease properties of pigmented polyphenols, such as flavonoids, anthocyanins, and tannins among other phytochemicals localized mainly in berry peels (skins) and seeds. Related to the biological properties of berry pigments is antioxidant ability for which berries are notable due to their relatively high oxygen radical absorbance capacity ("ORAC") among plant foods. Together with good nutrient content, ORAC distinguishes several berries within a new category of functional foods called "superfruits", a rapidly growing multi-billion dollar industry which began in 2005.

Botany

In botany, the berry is the most common type of simple fleshy fruit; a fruit in which the entire ovary wall ripens into an edible pericarp. The flowers of these plants have a superior ovary and they have one or more carpels within a thin covering and very fleshy interiors. The seeds are embedded in the common flesh of the ovary. Examples of botanical berries include the tomato, grape, litchi, loquat, plantain, avocado, persimmon, eggplant, guava, uchuva (ground cherry), and chile pepper.

The fruit of citrus, such as the orange, kumquat and lemon, is a modified berry called a hesperidium. The fruit of cucumbers and their relatives are modified berries called "pepoes". A plant that bears berries is referred to as bacciferous.

Sour orange, Citrus aurantium

Fruits of all members of the genus Citrus are considered berries because they have many seeds, are fleshy and soft, and derive from a single ovary. The distinctive fruit is a hesperidium in that it is a specialized berry with the internal fleshy parts divided into segments (typically 10 to 16) and surrounded by a separable rind (Katz and Weaver 2003).
