Abstract

Olive oil is a product of high quality and worth, presenting a basis for the Mediterranean diet, as well as other diets. The high quality of olive oil is not only achieved by the way it is produced, but also the the way is kept. Fact is that olive oil is frequently exposed to high temperatures and sunglight, which can influence its quality just the same with consumers, as with manufacturers and distributers. The aim of this paper is to simulate temperature regimes in a laboratory and measure the length of exposure of olive oil to those high temperatures, paying special attention to the total acid number of the oil, the oil quality parameters, such as the peroxide value, K – value, as well as change in structure of fatty acids, including change of sensory properties. Through analysis it was established that temperature and ways in which olive oil is being kept have significant effect on how the oil quality changes, especially when talking about the total acid number and the peroxide number. That being said, it is extremely important the oil is kept in appropriate containers, those being small glass bottles, as well as moved from direct sunlight and therefore high temperatures.

Keywords
