Evaluation of oil extraction of magdalenae Triportheus and lipid profile analysis of the crude oil
Abstract
Performance in the chemical extraction of oil from the fish species Arenca ( Triportheus magdalenae ) by the prior application of two types of digestion (acid and acid - alcohol ) was evaluated through an experimental design of randomized complete block ( RCBD ) . Oil extraction was done by soxhlet chemical method ; (adapted from the method 960.39 , AOAC meat ) and the analysis of the lipid profile of the crude oil was performed by gas chromatography , showing that the two types of digestion applied produce an increase in chemical yield of the oil extraction yield better performance with acidic digestion , according to Media Significant Difference ( LSD) at P <0.05 . It was determined that the T. magdalenae , presents a number of crude oil averaged 3.23% , dominated by unsaturated fatty acids ( AGI) , a 56.77 % ratio with essential fatty acids of the omega-3 ( ω -3) and omega 6 ( ω -6) , among which the eicosapentaenoic (EPA ) , docosapentaenoic ( DPA ) and to ω -3 linolenic , linoleic and arachidonic to ω -6. The results allow us to consider as a viable species studied to obtain oils, pharmaceutical and medicinal properties.
