The effect of photo-oxidized groundnut oil on the liver enzymes of albino rats was studied by measuring the biochemical indices of the rats fed with photo-oxidized groundnut oil. Physicochemical measurement of the groundnut oil exposed to sunlight for 90 hours was carried out to determine the effect of sunlight on the quality of the oil. The physicochemical parameter studied was relative density, viscosity, peroxide value and free fatty acid value. The result obtained show that the relative density, viscosity peroxide value and free fatty acid value increased with exposure. Biochemical analysis was conducted to determine the effect of photo-oxidized groundnut oil on the liver condition of the albino rats. Biochemical indices of liver function determined include Aspartate aminotransferase (AST), Alanine amino transferase (ALT) and alkaline phosphate (ALP).The result show increase in AST, ALP and reduction in AIT in rats fed with oxidized oil-based diet.
