Аннотация: Due to the peculiarities of the chemical composition, edible fats easily undergo changes during storage when exposed to sunlight and other types of radiation, which reduces their quality and biological value. This article examines the effect of light on the quality of food products and the processes occurring during the oxidation of food. To protect against solar radiation, tinted glasses are used, their efficiency being low. The authors proposed transparent protective films of indium tin oxide (ITO), which block UV and IR radiation, as well as electromagnetic fields. A method for producing oxide films on large-scale and complex surfaces is considered. The properties of ITO films to block UV and IR radiation can be used to protect food products by covering the glass container in which the product is stored with an ITO film. The acid and peroxide values of sunflower oil in glass containers both protected with films of indium tin oxide and unprotected ones are studied. When the product is stored under glass with a transparent ITO film, the acid value and peroxide value increased more slowly than without the protective film.
