Sunflower seeds
Sunflower seeds are found in plant fruits and are rich in vegetable fats, vitamins, proteins and minerals.
They have almost the same amount of proteins as steak and are an excellent source of dietary fiber, vitamin E, vitamin B and minerals such as potassium, magnesium, iron, phosphorus, selenium, calcium and zinc.
Seeds are usually classified according to form of their shells. There are black (also known as oilseed rape), striped (which are primarily used for food) and whitish which, currently, have no commercial usage.
Sunflower seeds are, at the same time, food and raw materials for food industry, primarily for production of oil and in bakery industry.
In the future, sunflower oil could become a renewable bio-source for hydrogen.
