Sunflower seed
Sunflower Seed
Sunflower seed (/ˈsʌnˌflaʊər siːd/) is the fruit of the Sunflower (Helianthus annuus). The term "sunflower seed" is actually a misnomer when applied to the seed in its pericarp (hull). Botanically speaking, it is more properly referred to as an achene.
Etymology
The term "sunflower seed" is derived from the plant's common name, "sunflower," which in turn comes from the flower's appearance, which is reminiscent of the sun. The word "seed" comes from the Old English "sæd," which has a general meaning of "seed, offspring, progeny."
Description
Sunflower seeds are usually classified by the pattern on their husks. If the husk is solid black, the seeds are called black oil sunflower seeds. The crops may be referred to as oilseed sunflower crops. These seeds are usually pressed to extract their oil. Striped sunflower seeds are primarily used for food; as a result, they may be called confectionery sunflower seeds.
Nutritional Value
Sunflower seeds are rich in Vitamin E, B vitamins, and dietary fiber. They also contain relatively high levels of protein and are thus an important source of plant-based protein. They are also a good source of minerals such as magnesium and selenium.
