Tiger nut and its by-products valorization: From extraction of oil and valuable compounds to development of new healthy products

At this stage of development, tiger nuts by-products are underutilized at an industrial level. For example, the literature about the oil extraction from tiger nuts by-products is scarce and most of the studies have been focused on the use of conventional (Soxhlet) extraction of oil. This review provides an overview of some of the most relevant innovative processing technologies to allow the industrial sustainability and green recovery of oil from tiger nuts and their by-products and, tries to expose potential avenues for future research in commercial exploitation of tiger nuts and its by-products as source of ingredients to be incorporated in new food matrices to improve their technological and functional aspects.
