摘要

The date fruit is widely recognized as a staple food in Arab countries, due to its many health benefits and ability to provide essential nutrients. However, most Moroccan varieties, particularly those of low market value, have not been sufficiently studied with regard to their morphological, physicochemical and biochemical characteristics. The aim of this work is to improve the morphological, physicochemical and biochemical characterization of four date varieties, three with low market value (Jdar Lahmer and Khalt Khal, harvested in Zagora, and Rasse Tmar, harvested in Erfoud), and one with high market value (also harvested in Erfoud). The harvest was conducted over two seasons, in 2021 and 2022. The morphometrical results of the date varieties studied showed that the Majhoul variety generally performed better in terms of weight, size and flesh-stone ratio, compared with other varieties with low market value such as Khalt Khal and Jdar Lahmer. However, physicochemical and biochemical characterization of the varieties revealed that the dates are rich in sugars (from 48.94% to 80.93%), while containing relatively low concentrations of proteins (1.75% to 3.50%) and lipids (0.26% to 0.79%). The predominant mineral is potassium, with levels varying between 907.64 mg and 1,233.52 mg/100 g of dry matter. In general, this physical, chemical and biochemical characterization shows that varieties with low market value have comparable or even higher nutritional potential, particularly the Khalt Khal variety, than the Majhoul variety, which is widely recognized for its high market value.
