Abstract
Date palm seed is a rich source of minerals, fiber, carbohydrates, and contains high levels of antioxidant compounds, making it a cost-effective and beneficial ingredient for formulating food products in the country. The current research was conducted to investigate the mineral contents in the seeds of 15 cultivated date palm cultivars in Khuzestan province including native cultivars (‘Fersi’, ‘Satmaran’, ‘Zahidi’, ‘Deiri’, ‘Belyani’, ‘Bereim’, ‘Barhee’, ‘Sowaidani’, ‘Asharsi’, ‘Hallawi’, ‘Owaidi’, and ‘Piarom’), and imported cultivars (‘Medjool’, ‘Deglet Noor’, and ‘Thoory’), at the Date Palm and Tropical Fruits Research Center of Iran. These cultivars were analyzed using a completely random design with three replications. The results showed, there are significant differences in the mineral contents, including Fe, Mn, Cu, Zn, Na, K, and Ca in the seeds of different date cultivars. K had the highest content in date palm seeds compared to other elements, followed by Ca, Na, Zn, Fe, Mn, and Cu. The highest levels of Fe and Mn elements were observed in the seed of the ‘Deiri’ cultivar, while the highest levels of Cu and K were found in the seeds of the ‘Medjool’ cultivar. The ‘Deglet Noor’ cultivar had the highest contents of Na and Ca in its seeds. Also, the highest concentration of zinc element was detected in the seed of the ‘Barhee’ cultivar. In different date seeds, the highest positive and significant correlation was observed between Ca% and Na%. Based on the cluster analysis results, regarding seed mineral contents, the examined date palm cultivars were classified into four main groups. Overall, the seeds of examined date palm cultivars, contained significant but highly variable amounts of minerals, and the use of seeds from the ‘Deiri’ and ‘Barhee’ (native cultivars) and ‘Medjool’ (imported cultivar) is recommended as important components in the production of functional food products in the country.
