As shown in Table 1, for each harvested sample the kernels rep-resented about 13% of the total depulped fruit weight (dry whole nut). However the variability of the kernel to nut (depulped fruit)ratio tends to increase with time, the SD passing from 1.2 to 1.5,then 2.0 (Table 1). The oil content as extracted with hexane was also similar for each batch, independently of the harvest date. This lack of significant differences neither between the kernel/nut ratio, nor regarding the oil content, all based on dry weight, tends to show that harvest date does not quantitatively impact oil production,over the limited investigated maturation period of three months,which is actually the end of the production stage. Therefore, further analyses were performed to evaluate the impact of fruit ripening on Argan oil quality. For convenience, this exploratory study being performed at laboratory scale, the oil was extracted with solvent following a standard analytical procedure, and not with a screw press.
