Abstract:
Currently, large quantities of fruit waste are generated in and industrial and artisanal way, mainly by food manufacturing companies. In the case of mango, the seed represents 17-25% of the total weight of the fruit. In Colombia, more than 200,000 tons of mango are produced per year, which would generate up to 50,000 tons of discarded seeds. Taking advantage of the opportunity to generate value-added products, from waste, the use of mango seed oil for the generation of Biodiesel is considered a viable option. Biodiesel is a notable alternative to diesel fuel derived from widely used petroleum since it can be generated by domestic natural resources such as seed oil, coconuts and even recycled cooking oil. The optimal supercritical extraction conditions worked were 40 ° C, 300 Bar, 4 ml/min of CO2 flow and 1 ml/min of cosolvent flow (Isopropanol and ethanol). In this work it was found that the average supercritical CO2 extraction yield of Keitt mango seed was 17.56% and 6.29% with isopropanol and ethanol as cosolvents, respectively. Triplicate catalyzed transesterification reactions were performed with NaOH as a catalyst with a catalyst-oil ratio of 0.1: 1, Methanol: oil ratio of 1: 7, 60 ° C reaction temperature and reaction time of 90 min, finding reaction yields of 87.94% and 68.74% for the oil extracted with cosolvent Isopropanol and ethanol respectively. Tests and analyses were carried out to determine the physical properties of the product. The density of 857.5 kg / m3, cloud point index of 27.6 °C, pour point of 17.8 ° C, saponification value of 116.41 mg KOH/g, iodine value of 45.68 mg I /g and cetane number of 36.07.
