Abstract:
Nowadays nearly 12 million tons of wastes are produced in Colombia [1] in which the 53% are organic residues such as fruit peels[2]. These residues represent a great opportunity of energy conversion and value-added products in agro industrial companies that export dry fruit and pulp from fruits such as banana, dragon fruit, goldenberry, mango and pineapple. First of all, a proximate compositional analysis was done in order to determine specific quantities of total solids, ash, extractives, protein, lignin, cellulose, hemicellulose and pectin. The production of biogas, the extraction of pectin and the use of mango kernel oil to formulate cosmetic products are some of the possibilities studied to benefit from agro industrial fruit waste. NREL Biomass Compositional Analysis Laboratory Procedures were used to identify main biomolecules in residues and an additional method for quantification of pectin was proposed and included as it is not considered in conventional lignocellulosic biomass compositional analysis protocols. Biological methane potential (BMP) was tested for each fruit using swine manure as inoculum following a modified VDI4630 anaerobic digestion procedure. A colorimetric method to determine the amount of peptic substances was used to quantify pectin in fruit waste and an extraction method was performed varying temperatures, times of removal and pH. Finally, limonene was used as a natural solvent to retrieve mango oil from its kernel and used to formulate a moisturizing cream containing guar gum as thickening agent.
