Abstract

Frying food is one of the most admired methods to make instant cuisine among people because of its taste and color, as well as the crispy texture creation. Hydrogen peroxide which is the result of frying, causes various diseases, including cancer, atherosclerosis, cardiac and cerebral ischemia, aging and liver disorders. Therefore, this study aims to investigate the amount of peroxide in the oils used in bistros in western Iran. This descriptive cross-sectional study carried out in the restaurants in western Iran. In this study, 81 samples of consumable oils gathered according to the standard of 493 Iranian Institute of Standards and Industrial Research. After transferring the samples to the laboratory, there peroxide value was measured according to the standard number 4179 and data was entered in Excel and SPSSVersion 16 for further analyses.Out of 81 samples, 59% (48 samples) from consumable samples at the standard level and 41% (33 samples) of the non-consumable samples higher than the standard rate of the Institute of Standards and Industrial Research of Iran. While cooking, the consumable oil average peroxide value was 5.72, without a night and day breakdown (in general). In addition, the lowest and highest peroxide oxidation was 0 and 29 mEq/kg. According to Mann-Whitney test, there was no significant difference between the amounts of peroxide in consumable oils.some evidence shows the non-compliance with hygiene issues that are related to oil consumption. This requires more supervision and continuous sampling and testing. © 2018, Advanced Scientific Research. All rights reserved.
