title: Fatty Acids and Bioactive Lipids of Potato Cultivars: An Overview.
abstract: Potato tuber is a highly nutritious, wherein genotype and environmental differences are known to exist in the shape, size and nutritional value of potatoes. Owing to its high consumption, potato could be an ideal carrier of health-promoting phytochemicals. Potato cultivars contain many bioactive lipidic compounds such as fatty acids, glycolipids, phospholipids, sterols, tocols and carotenoids, which are highly desirable in diet because of their health-promoting effects. In the scientific literature, information on the content and profile of bioactive lipidic compounds in potato cultivars are few. The concentration and stability of bioactive lipids are affected by many factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions. In this review levels and composition of bioactive lipids in terms of lipid classes, fatty acids, phytosterols, tocopherols, and caroteinoids distribution in different potato cultivars including genetically modified potato (GMP) were highlighted and discussed. In addition, factors affecting bioactive lipids levels, stability and health benefits are reviewed. In consideration of potential nutritional value, detailed knowledge on lipids of potato cultivars is of major importance.
