Extraction of Oil from Avocado Fruit for Shampoo Production

Abstract

The main aim of this study is to determine the optimum extraction of oil from avocado fruit. For this, particle size of 0.5mm and 1mm, solvent type (hexane) and extraction time of 4hrs and 6hrs were considered for optimization. When the particle size range decreased from 1mm to 0.5mm the oil yield increased for solvent type and with a certain extraction time. As extraction time was increased from 4hr to 6hr the oil yield increased from 15.73% to 20.68% for particle size 1mm and 0.5mm respectively. Different physico-chemical properties of the produced oil were characterized, and its values were recorded, such as acid value, specific gravity, pH value and, free fatty acid values are 0.214%, 0.9126, 6.8, and 0.107% respectively. From 160gm sample powder avocado 69.91ml of oil was found. The produced shampoo was characterized and its physical property values are calculated such as foam ability and stability, visual inspection, detergence ability and surface tension. From the result the characteristics were good foaming capacity, moderate dirt dispersion, yellowish color, fine and smooth texture and nature of hair after wash was soft and manageable. From the techno economic feasibility analysis, the rate of return (ROI), 21% and payback period 2.8 years were found.
