Publisher Summary Sunflower seeds are mainly used for their oil, but as with other oilseeds, the meal left behind after oil extraction is a valuable product because of its high protein content. Sunflower seeds are attractive due to their high protein content and extensive availability. Compared to other vegetable protein sources, sunflower seeds contain low or no anti-nutritional factors and, except for lysine present at low concentration, their amino acid composition conforms to the Food and Agriculture Organization outline of human requirements. Sunflower protein consists largely of albumins and globulins and, consequently, has a high intrinsic solubility. Nowadays, the main market outlet for sunflower protein relies on animal feed. This chapter discusses sunflower proteins, principally seed proteins, including composition, structure, stability, and biochemical and molecular characterization. |
