Physical Fruit Traits, Nutritional Composition, and Seed Oil Fatty Acids Profiling in the Main Date Palm (Phoenix dactylifera L.) Varieties Grown in Morocco

Table 2

Mean values of proteins content (PC, % DW), carbohydrates content (CC, % DW), ash content (AC, % DW), moisture content (MC, % DW), oil content (OC, % DW), and reducing capacity (RC, mg GAE/100 g fruit DW) and energy value (EV, kcal/100 g) for date fleshes and seeds from eight Moroccan varieties. All values are means ± standard deviation of three replicates. Different letters within a column indicate significant statistical differences (). DW: dry weight.
