Variability of fat content and fatty acid composition in oil of dwarf coconut palm at its maturation time
Keywords:
coconut, dwarf coconut, Cocos nucifera L, pulp, fat, fatty acids
Abstract
Coconut palm has been considered “the tree of life” since several products have been feasible to beobtained, especially from its fruits. In the present study, the fat content and the fatty acid compositionwere determined in the pulp of dwarf coconut (six cultivars, aged from 6 to 12 months), cultivated in CampoExperimental do Betume, EMBRAPA, Neopolis City, Sergipe State, Brazil. Fat content was evaluated bySoxhlet technique , and fatty acid profile was determined by means of gas-chromatographic technique. Allof the samples presented low amounts of fat, increasing the fat level in proportion to the age until 11months (25.4 g/100 g). Red dwarf coconut pulps from Cameroon and Malaysia revealed high content oflauric acid (from 38.1 to 49.6 g/100 g of oil), providing its use for soap manufacturing and detergentindustries.Key WordsReferences
