Bucktons Sunflower Hearts 20k For commercial purposes, 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 into sunflower oil. These seeds are considered the seed of choice for bird feeders. If the husks are striped, the seeds are called striped sunflower seeds or “stripers.” Due to their lower oil content, the crops are called non-oilseed sunflower crops. Striped sunflower seeds are primarily used for food; as a result, they may be called confectionery sunflower seeds. In addition to linoleic acid (an essential fatty acid), sunflower seeds are also an excellent source of dietary fiber, protein, Vitamin E, B Vitamins, and minerals such as potassium, magnesium, iron, phosphorus, selenium, calcium and zinc. Additionally, they are rich in cholesterol-lowering phytosterols.
