Improper conditions during the oil storage period have a significant impact on their low quality and the most important change is the oxidation of oil known as oil shale. Which leads to the bad taste and smell and the most important factors affecting the oil during storage during storage are:
1 - Oxygen: The exposure of oil to atmospheric oxygen during the process of filtering and marketing or through oxygen dissolved in oil leads to oxidation and thus to be scaled. The greater the surface of oil contact with oxygen, the greater the oxidation process. This requires the tanks and vessels to be fully oiled and sometimes inactive gases (Ozone 0 Argon) are used to dispose of oxygen, which is the most common method of oil in the world.
2 - Temperature: The high temperature in oil reservoirs lead to the activation and speed of the process of oxidation, and the temperature between 10-15 ° C is ideal to prevent oxidation and this degree does not cause the turbidity of oil and it is better to use temperatures lower than that.
3 - Lighting: Direct or indirect solar radiation has an effect on oil oxidation process by activating the chlorophyll oil and UV rays are more harmful to oil during storage.
4. Minerals: Metals negatively affect the quality of oil during storage, especially iron and copper, as it plays an energizing role to increase the process of oxidation, usually the source of these minerals from the metal surfaces of the machines of the age and vessels used in conservation.
5 - Free fatty acids: The process of oxidation increase free fatty acids due to the rapid reaction between oxygen and free fatty acid while the rate of reaction when the acids are linked, so the high acidity of oil encourages the process of pruning during storage.
