Studies on the Physico-chemical Properties and Pharmacology of Heated Edible Oils

Abstract

The present study was carried out to evaluate the physico-cheniical properties like iodine value, acid value and compare FT-IR spectra of unheated and heated edible oils, the effects of consumption of heated edible oils diet oil blood lipid profile, biochemical parameters and hematological profile of rabbits. On the other hand, the present study aimed to observe the histological change in rabbit liver, kidney, heart, lung, brain and spleen tissues after feeding heated edible oils. The experimental data showed that the lowest iodine value and the highest acid value were observed in 20 hours heated palm oil (18.02±0.05), (7.01±0.03) and soybean oil (83.06±0.08),(5.68±0.05) respectively. The spectra of unheated and 2, 10, 20 hours heated palm and soybean oils showed very similar FT-JR spectra in this study. The body weight of experimental rabbit 20 hours heated palm oil diet group P3 (821.57±3.29 gm) and similar soybean oil diet group S3 (730.50±2.20 gm) were higher than that of control group. Total white blood cell (WBC) of 2 hours heated palm oil diet group P1 (9.5x10 3±0.16x103 blood cell/121), red blood cell (RBC) of P3 group (6.58±0.03 in! .tl), platelet count (PC) of 10 hours heated palm oil diet group P2 (593±2.44 thousand/jt!) were higher than that of fresh normal rabbits. Creatinine of S3 group (1.1±0.08 mg/dl), serum glutamic pyruvic transminase (SOPT) of P3 group (8 1±2.16 UIL), serum glutamic oxaloacetic transminase (SGOT) of P3 group (147±0.82 LJ/L) and uric acid of P2 group (1.9±0.08 mg/d!) were higher than that of control group. The total cholesterol (TC) of P3 group (158±2.16 mg!dl), high density lipoprotein (1-IDL) of P3 group (57±1.63 mg!dl), low density lipoprotein (LDL) of P3 group (8 1±1.41 mg/dl) and triglyceride (TG) of P3 group (176±0.82 mg/dl) were found higher than that of untreated rabbits. Histopathological study of liver, kidney, heart, lung, brain and spleen of the heated edible oil treated rabbits showed abnormalities as compared to control group organs. Consumption of heated edibles oil may occur infection, stress, allergy, hepatic damage, anemia, vascular disease, renal system damage, liver cirrhosis, pulmonary infarction, coronary artery disease of the consumers. Liver, heart, kidney, lung, brain, spleen and muscles may be damaged by chronic consumption of heated edible oils.
