چکیده

The objective of this research was to investigate the effect heating temperature on quality parameters avocado and peanut oils subjected heating. Vegetable were heated at varying temperatures (110, 140, 170, 200 230�C for 30 min) follow alterations. Levels peroxide value, iodine thiobarbituric acid reactive substances, total polar compounds, refractive index, free acidity, fatty acids composition determined measure extent lipid oxidation. Peroxide value significantly (p [ 0.001) influenced by in case oil. Iodine decreased 0.01) both with increase due decrease unsaturation degree. Avocado oil showed smallest substances compounds during heat treatment. profile rich polyunsaturated a level 42%, followed monounsaturated about 36%. treatment has produced changes unsaturated acids, these have undergone isomerization from cis trans form. increases up deteriorated oil, but lesser one

Effect of cinnamaldehyde on oxidative stability of several fats and oils at elevated temperatures

Natural antioxidants recently have gained popularity since synthetic ones have toxic and carcinogenic effects. In the present study, effect of temperature (120, 150 and 180°C) and cinnamaldehyde on oxidative stability of several oils (olive, hazelnut and palm oils) and fats (milkfat and butter) was examined. In order to compare the results with the synthetic antioxidant, butylated hydroxy tolue...
