Bioactive compounds from date fruit and seed as potential nutraceutical and functional food ingredients

Abstract

Date palm is an important fruit bearing tree grown widely in the arid and semi-arid regions of the world. The date fruit and its by-products, such as seeds, have both nutritional and medicinal value. However, date fruit and seeds have not been fully considered as potential functional food ingredients to develop foods with promising health benefits. Based on the available information in the literature, fruit and seed of date palm are rich in phytochemicals, such as phenolics, anthocyanin, carotenoids, tocopherols, tocotrienols, phytosterols and dietary fiber. In addition, they were reported to possess several beneficial health properties explored under in-vitro and in-vivo conditions. Further research in this area would provide valuable information for the potential utilization of date fruit and seed as functional food ingredients. This review presents a comprehensive information about the bioactive compounds and nutraceutical properties of different varieties of date fruit and seed, as well as the potential for using them as functional food ingredients.
