The Peanut or Groundnut or Arachis oil (Arachis Hypogaea) is a species in the legume or "Bean" family (Fabaceae). The Peanut was probably first domesticated and cultivated in the valleys of Paraguay. It is an annual herbaceous plant growing 30 to 50 cm tall.
The specific name, Hypogaea
means "Under the Earth"; after pollination, the flower stalk elongates,
causing it to bend until the ovary touches the ground. Continued stalk
growth then pushes the ovary underground where the mature fruit develops
into a legume pod. Pods are 3 to 7 cm long, containing 1 to 4 seeds.
in botanical terms, "nut" specifically refers to indehiscent fruit, the Peanut is not actually a nut, but rather a legume. Peanuts grow best in
light, sandy loam soil. They require five months of warm weather.
Peanut oil has a pleasing and sometimes light nutty flavor. In addition to its great taste. Sweet, and flavorful Peanut oil is organic edible oil obtained from pressing Peanut kernels.
Its major component fatty acids are oleic acid (46,8% as olein), linoleic acid (33,4% as linolein), and palmitic acid (10,0% as palmitin). The oil also contains some stearic acid, arachidic acid, arachidonic acid, behenic acid, lignoceric acid and other fatty acids. Antioxidants such as Vitamin E are sometimes added, to improve the shelf life of the oil.
Shelf life of Peanut oil
is about six months in ordinary conditions. When preserved in an
airtight container in cool, dry, dark and moisture-free environments its
quality may remain good for up to nine months. Its shelf may be
extended for more than 12 months with the addition of antioxidants like Vitamin E.
