Under normal storage conditions, peanut oil will undergo an auto-oxidation and rancidity process, and its changes are as follows: the auto-oxidation process is related to the season. If it is stored in winter, low temperature can effectively delay the reaction of lipase and oxygen. With the change of seasons and the rise of temperature, when the temperature is between 15-30℃, on the one hand, A lipáz hatása miatt az olajat hidrolizálják, és a savérték növekszik .} Az oxigén infiltrációja a levegőben elősegíti az olaj oxidációját, hogy hidroperoxidokat képezzenek .
In summer, the room temperature and the tank temperature exceed 30℃. If it is stored in an open-air oil tank or an open-air yard, it will be exposed to sunlight every day. In this case, environmental factors will accelerate the oxidation process of oil. Especially in the sunlight, under the action of ultraviolet rays or metal catalysts, when the radiation temperature exceeds 50 A fok, a peroxidok és a hidroperoxidok tovább bomlanak, majd a molekulákat aldehidekbe és ketonokká alakítják át, így a tárolt olaj rántja .
