Peanut
Peanut (Arachis hypogaea)
Peanut (pronounced /ˈpiː.nʌt/), also known as the groundnut, goober, or monkey nut (UK), is a legume crop grown mainly for its edible seeds. It is classified as both a grain legume and, due to its high oil content, an oil crop.
Etymology
The term "peanut" is derived from the combination of the English words "pea" and "nut", referring to the fact that it is a nut that grows in pods like peas. The scientific name, Arachis hypogaea, is a Latin name that means "underground nut".
Description
The peanut plant is a small, usually erect, bushy plant that grows up to 1.5 feet tall. The leaves are opposite and pinnate with four leaflets. The flowers are a typical peaflower in shape, 2 to 4 cm (0.8 to 1.6 in) across, yellow with reddish veining.
After pollination, the fruit develops into a legume 3 to 7 cm (1.2 to 2.8 in) long, containing 1 to 4 seeds, which forces its way underground to mature.
Uses
Peanuts are used in a variety of culinary applications. They are used whole in confectionery products and desserts, ground into peanut butter, and pressed for peanut oil. They are also used in a number of cultural dishes worldwide.
Health
Peanuts are rich in essential nutrients, including proteins, fats, and various vitamins and minerals. However, they can also be a source of allergies, with peanut allergies being one of the most common food allergies.
