The objective of this work was to evaluate the location effect on physicochemical, techno-functional, mineral and amino acid profile of two Moringa tissues (leaflets and petioles). Methods: Two Moringa tissues grown in three different locations were characterized physicochemically (fat, fiber, moisture, protein, carbohydrates), techno-functionally (water-holding capacity, swelling capacity, oil-holding capacity and organic molecule absorption capacity), mineral (by fluorecancer x-rays) and aminoacid (by HPLC). Results: Results indicated that leaflets showed higher dry matter content (89.40 ± 0.86 %), ash (11.66 ± 0.59 %), protein (34.61 ± 3.75 %), fat (15.01 ± 1.51 %), water-holding capacity (5.03 mL/g), and swelling capacity (7.28 cm3/g) compared to petioles which presented higher fiber content (36. 21 ± 3.75 %), oil-holding capacity (2.67 g oil/g), and organic molecule absorption capacity (2.91 mL oil/g). In addition, leaflets showed a higher mineral content in comparison to petioles, in both tissues, the major elements were Ca, K, Mg and S. On the other hand, leaflets showed a higher content and diversity of essential and nonessential amino acids. Conclusion: In conclusion, quality and physicochemical, techno-functional, elemental and amino-acid profile are affected by tissue and location.engAmino acidsChemical elementsHPLCLeafletsPetiolesX-Ray fluorescenceresearch article10.1016/j.jtemin.2025.100258105012950769
