For thousands of years olive oil has been stored in terracotta containers which were glazed on the inside to reduce absorption of the oil into the clay. With the invention of new materials, olive oil storage tanks are now made from high-quality, food grade stainless steel. These tanks range in size from 5L to the large 80,000L tanks. Olive oil has an interesting characteristic in that it acts like a sponge in its ability to soak up surrounding fragrances. This makes it very important to store your oil away from foreign substances which will directly affect the character of the oil. A few problems to watch our for are: smoke from cigarettes, fires etc. fumes from machinery working within the processing area. non-stainless steel components in extraction equipment. non stainless steel storage containers (glass bottles are fine).
Also, other factors can also affect the quality of your oil which include air, light, heat, water and too much sediment. Light speeds up the oxidation process which shortens the shelf life of the oil. Oil should always be stored in containers which have a minimal amount of air below the lid. Air also speeds up the oxidation process. Extremes of temperatures can also oxidise your oil. If water and heavy sediment are present in your oil, it is imperative to make sure you decant your oil from the container to another clean container to minimise oxidation rate. When water comes into contact with the oil some of the keeping properties of the oil are present in the water. It is very important to invest in the correct storage if you want to maintain the highest quality possible. To see suitable stainless steel press this link. |
