Sunflower Seed

A sunflower seed is a seed from the sunflower plant, of which there are three commonly used types: linoleic, the most common, high oleic, and sunflower oil seeds, each with its own distinct balance of monounsaturated, saturated and polyunsaturated fats. Commercially, sunflower seeds are usually classified by the pattern on their husks, with solid black husks marking black oil sunflower seeds, which are usually pressed to extract oil, while striped sunflower seeds are primarily eaten as a snack food and known as confectionery sunflower seeds. Botanically the seed in its hull is a type of dry fruit called a cypsela rather than a true seed.
