Characteristic Profiles of an Original Drink Sap from Male and Female Deglet Nour Palm (Phoenix dactylifera L.) during Collection Period

This work aimed to evaluate the nutritional quality of a typical natural drink from male and female Deglet Nour (DN) date palm (Phoenix dactylifera L.) during the collection period. Dry matter, protein, amino acids, and sugar profiles were determined using AFNOR norm, Kjeldahl method, HPLC, and HPAE...

description This work aimed to evaluate the nutritional quality of a typical natural drink from male and female Deglet Nour (DN) date palm (Phoenix dactylifera L.) during the collection period. Dry matter, protein, amino acids, and sugar profiles were determined using AFNOR norm, Kjeldahl method, HPLC, and HPAEC-PAD, respectively. The male sap dry matter content was higher than that of the female. It decreased significantly through the tapping period. During the harvest, the male sap protein content decreased but increased significantly in the female sap. Finally, sugar fraction, for both male and female DN sap, was dominated by sucrose, glucose, fructose, and a small amount of myo-inositol. During the collection time, sugar content is affected by the sex especially for myo-inositol content that increased significantly in the female date sap, unlike that of the male one. This may be related to the fact that the male palm is more resistant to physiological stress, inducing myo-inositol formation during tapping.
