Abstract:
Currently, about 10 million tons of fruit and vegetables are produced in Colombia per year, of which 58% is converted into organic waste by loss in the stages of production, storage, and industrial processing. The fruit waste is composed of husk and seed and the main way of disposal is through landfills. Thus, fruit waste is an economic and environmental problem, whose impact can reduce through the chemical and biological recovery of the waste. This project proposes the design of a cosmetic product of added value from the residues of the fruit of the peach palm, known locally as “chontaduro” and açai. Therefore, the compositional analysis and the characterization of phytochemicals in peach palm (Bactris gasipaes) and açai (Euterpe oleracea) fruit residues were carried out, in order to evaluate the potential of its compounds as a raw material in the development of the cosmetic product. All characterization processes of biomass were performed following the methodology of the NREL Biomass Composition Analysis Laboratory. Thus, specific amounts of total solids, ash, extracts, protein, lignin, cellulose, hemicellulose and pectin were determined in the residues. The extraction potential of the available bioactive compounds was evaluated with solid-liquid extractions in single stage, cross stage and inverted cross stage. A factorial design with 3 factors and two levels was carried out: type of sample, type of solvent, type of extraction, in order to evaluate the yield of the percentage of phytochemical extraction of the waste. Subsequently, the presence of phytochemicals in the extracts was analyzed using colorimetric tests, hence flavonoids, leucoanthocyanidins and tannins were identified in the açai seed, as well as saponins, alkaloids, sterols and carotenoids in peach palm seed and peel. In addition, bioactive compounds from leaching extraction were characterized by tests of total phenols and antioxidant capacity. Finally, based on the composition of the fruit residues in terms of their phytochemical value the design of a value-added cosmetic product could be proposed.
