Variation of Soluble Sugar and Minerals Contents of Kernels from Germinated Nuts of Several Coconut Cultivars (Cocos nucifera L.)

Aims: This study aimed to assess the soluble sugars and minerals in coconut kernels during the fruits’ germination.

Place and Duration of Study: Marc Delorme Research Station for coconut, National Agronomic Research Center, Abidjan, Côte d’Ivoire, between March and May, 2010.

Methodology: The germinated nuts kernels of three coconut cultivars, namely West African Tall (WAT), Malaysian Yellow Dwarf (MYD), and improved hybrid ‘PB121+’ were investigated. The soluble carbohydrates profile and the mail minerals were evidenced using chromatography methods.

Results: The overall coconut kernels studied recorded the same carbohydrate compounds, main of which are myo-inositol, sorbitol, glucose, fructose and sucrose. The result shows sucrose as the major carbohydrate in the germinated nut kernel whatever the coconut cultivar. The three coconuts also displayed the same mineral elements, especially sodium, magnesium, phosphorus, sulfur, and potassium. They are more richer in potassium and phosphorus.

Conclusion: Thanks to the great soluble sugars and minerals contents, the germinated coconut kernel could be valorized as a good food resource or used as food additive for children suffering from mineral troubles.
