The present study aims to demonstrate the influence of extraction processes on the oil obtained from the mature albumen of the nut of the coconut hybrid NJM x GVT. Three oil extraction processes were studied. These are the traditional variable temperature extraction methods, at constant temperature (105 ° C) and then the soxlhet extraction method (control method). The physicochemical characteristics of the extracted oil such as pH, density, acid number (Ia), iodine number (Ii), peroxide number (Ip), index of saponification (Ip) and the contents of two major fatty acids, lauric acid (C12) and myristic acid (C14), were determined there. The results indicated that the oil yield obtained with the soxlhet reference method (65.79%) is high than that of the two traditional methods at variable and constant temperature (respectively 38.28 to 39.9%). The oil extracted using these three techniques is acidic (pH<7) with a more pronounced acid number compared to traditional variable temperature extraction (10.41 mg KoH / g). The traditional constant temperature method has an acid number close to that of soxlhet (1.34 mg KoH / g oil) This acidity thus obeys the standards of the Codex Alimentarius (Ia ≤ 4 mg KoH / g of oil). The extraction methods had no influence on the peroxide value. Thus, traditional extraction is best at constant temperature.

L'hybride F1 NJM x GVT est un cocotier créé pour lutter contre la maladie du jaunissement mortel du cocotier. Cet hybride a été montré tolérant à la maladie du jaunissement mortel du Ghana. Cependant, planté dans les conditions agro-climatiques de la Côte d'Ivoire, il a été peu étudié au plan biochimique. L'objectif de cette étude est donc d'évaluer les caractéristiques physico-chimiques de l'eau des noix immatures de cocotier issues des descendances d2, d3, d6, d7, d11 et d15 de l’hybride F1 NJM x GVT. Ainsi, ont été déterminés, la masse de l’eau des noix et ses teneurs en matière sèche, cendres, degré Brix, sucres totaux, sucres réducteurs, protéines et composés phénoliques à l’aide de méthodes standards. Les résultats obtenus montrent que les masses de l’eau et le degré Brix ont des valeurs plus importantes pour les descendance d2, d6 et d7. Quant aux eaux des descendances d3, d11 et d15, elles présentent des taux élevés de sucres totaux et de composés phénoliques. Cette hétérogénéité des paramètres physico-chimique de l’eau, offre un large éventail de choix de transformation au plan industriel (boisson, sirop, etc.). Mots clés : eau de coco, descendances, hybride NJM x GVT, caractéristiques physico-chimiques, jaunissement mortel, Côte d’Ivoire.   The F1 NJM x GVT hybrid is a coconut palm tree created to lethal yellowing disease. This hybrid has been shown to be tolerant of lethal yellowing disease of Ghana. However, planted under the agro-climatic conditions of the Ivory Coast, it has been little biochemical studied. The present study aims to characterize nutritive composites of immature coconut water from progeny d2, d3, d6, d7, d11 and d15 of F1 NJM x GVT hybrid. Thus, the contents of dry matter, ash, Brix degree, total sugars, reducing sugars, proteins, phenolic compounds and coconut water weight, were determined by standard analysis methods. The results obtained show higher values of coconut water weight and Brix degree in the group of progeny d2, d6 and d7. As for progeny d3, d11 and d15 the have high levels of total sugars and phenolic compounds. This heterogeneity of the nutritive parameters, offers a lot off choices in coconut transformation (drink, syrup, etc.).
