Oxidation parameters including peroxide value, malonaldehyde concentration and hexanal content were periodically followed during the storage to investigate the effects of metal ions and ascorbyl palmitate on oxidation of sunflower oil.
toxisperma (1 and 20%) with a peroxide value of less than 10 registered in this study is the characteristic of the majority of many edible vegetable oils [15, 19, 20, 21, 25].
Refractive index, density, specific gravity, surface tension, acid value, free fatty acid value, saponification value, iodine value, colour and peroxide value were carried out.
For the chemical characterization of different varieties of cottonseed oil, official methods were used to check oil content, iodine value, saponification value, peroxide value, free fatty acids and oxidative stability as reported in AOCS method [8].
Acid value, peroxide value, and thiobarbituric acid value: The acid values and peroxide values of chicken fat were determined using the AOAC method [13] and expressed as mg KOH/g and meq/kg, respectively.
Typical applications include the continuous measurement of protein, fat, lactose and total solids in milk products; chemical oxygen demand (COD) in waste water flow of dairies or cheese factories; and measuring free fatty acids, total polar material, peroxide value, moisture, dirt and other values during edible oil and fat processing.

Summary: The effects of rosemary extract (RE) and tert-Butylhydroquinone (TBHQ) on the storage stability of radish seed oil were studied according to the change of the acid value, peroxide value, tocopherol and sulforaphene in radish seed oil.
Once sufficient peroxide radicals are formed, the peroxide value grows exponentially prior to reaching a maximum as the rate of peroxide degradation outpaces that of peroxide formation, leading to an eventual decline in peroxide concentration [10].
