Abstract:
-The study employed Soxhlet extraction to determine the best conditions that would give optimum oil yield and oleic acid content of the Philippine avocado fruit variety no. 240. Two solvents, namely n-Hexane and Ethanol were considered in the extraction of the fruit flesh at varying extraction time and amount of the said solvents. Effects of varying time and amount solvent conditions were taken into account during extraction. Moreover, the fatty acid profiles of the oils extracted were analyzed using Gas Chromatography (GC). Physical and chemical properties were also tested for further elaboration of distinction of the Philippine avocado oil from the other varieties. The results showed that at a constant temperature of 1000C and 30 grams of freeze- dried pulp sample, using 350 ml of ethanol for an 8-hour extractiontime, an average of 69.78% of crude oil was obtained and an average of 40.71% for oleic acid content. On the other hand, n-Hexane showed off an average oil yield of 36.17% and 43.46% oleic acid composition for a 2-hour extraction, using 250 ml of solvent.
