Structural properties and antioxidant activities of polysaccharides isolated from sunflower meal after oil extraction

Making full use of sunflower seeds, including oil and the polysaccharides extracted from the meals which oil has been extracted, is one way to enhance their industrial value. Such meals contain abundant polysaccharides; however, the application of polysaccharides isolated from sunflower remaining me...
