Abstract

The physicochemical properties of oil extracted from sweet orange seed fruit discards in Ogbia were investigated. The oil was extracted from the powdered seed samples in a soxhlet apparatus using hexane and petroleum ether as solvents. A higher percentage yield (31.40 %) was recorded in the Hexane extract as compared to a 12.80 % yield for the petroleum ether extract. Citrus sinesis seed oil had a moisture/volatile matter content of 31.76 %, a peroxide value of 10.20mg/kg, free fatty acid (4.85 %). The acid value of the oil was 9.65±0.84 mg KOH/g and was in line with the acceptable limits of ≤10 mg KOH/g for edible oils. The iodine value was 102.2±3.66 mg ioding/100g and the oil had a saponification value of 196.65±4.87 mg KOH/g. This finding had shown that the waste seeds of C. sinesis could serves as a viable feedstock for the extraction of oil with possible industrial applications
