Comparative Evaluation of Physiochemical and GC-MS Analysis of Sour Oranges and Sweet Oranges Peels Oil

Abstract: The studied were carried out for the comparative evaluation of physiochemical and GCMS analysis of sour and sweet oranges peel oil of Pakistan. The physiochemical analysis of sour oranges were shown that moisture (%), density, iodine value (g/100g), saponification value (mg/g), peroxide value (mg eq/kg), free fatty acid value (%) 0.34 ±0.22, 0.92 ± 0.16, 100 ± 0.44 , 171 ± 0.32 , 35.2 ± 0.12 and 5.8 ± 0.31 respectively, while similarly the sweet oranges peels physiochemical analysis value were 0.42 ± 0.15 moisture (%), 0.94 ± 0.13 density, 103 ± 0.54 iodine value (g/100g), saponification value (mg/g), peroxide value (mg eq/kg) and free fatty acid value (%) were 183 ± 0.11 , 13.5 ± 0.17 and 2.3 ± 0.16 respectively. GC-MS analysis of sour orange and sweet orange peels oil were also calculated. The results of the present study demonstrated that the seeds of citrus species investigated are a potential source of valuable oil which might be utilized for edible and other industrial applications
