Progress on Nutritional Function and High-value Utilization of Hulless Barley

Recently, the hulless barley has drawn wide attention due to its abundant nutritional composition and unique biological activities. Resistant starch, lunasin polypeptide, unique fatty acid and non-starch polysaccharide composition and rich phenolic substances make hulless barley have good development potential in anti-cancer, hypoglycemic, hypolipidemic and other aspects. However, the low degree of processing and utilization and the rare of high value-added products hinder the development of the hulless barley industry. The components, biological activities, processing and utilization technology and high-value products of hulless barley are summarized in this paper to provide support for promoting the research and sustainable industry development of hulless barley.
