Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a food oil peroxide value detection device. Background Technology

[0002] Peroxide value testing of food oils is an important indicator for measuring the degree of oxidation of oils and fats, and is used to determine whether oils and fats have deteriorated due to oxidation. The main testing methods include titration and colorimetry. In the testing process, some specific instruments and reagents are required, such as electronic analytical balance, rotary evaporator, electric thermostatic drying oven, thermostatic water bath shaker, high-speed refrigerated centrifuge, etc., as well as reagents such as petroleum ether, anhydrous sodium sulfate, chloroform-glacial acetic acid mixture, saturated potassium iodide solution, sodium thiosulfate standard solution, etc.

[0003] The following problems exist: The detection of peroxide value in food oils mainly adopts the titration method, which utilizes the reaction of peroxides generated during the oxidation of oils with potassium iodide to generate free iodine, which is then titrated with sodium thiosulfate solution to finally calculate the peroxide value. However, since the process of reacting peroxides with saturated potassium iodide to generate free iodine requires manual shaking, it not only places a heavy burden on the testing personnel, but also cannot guarantee whether the shaking results meet the standards.
