Influence of storage temperature on selected quality characteristics of nuts’ oil

Abstract

Vegetable oils cold pressed are among the most stable during storage, but also subjected to the processes of lowering their quality during storage. The kinetics of these changes depend on many factors, including temperature storage. Recently, there is an increase in supply and more diversified range of vegetable oils in new, previously not present on the Polish market products. Such oils are, for example, oils prepared from the nuts. Due to the fact that the most common cause of deterioration of oils is oxidation, studies on oxidation during storage of three nut oils at temperatures 4oC and 20oC were carried out. The research material was stored 6 weeks. The results showed that at 4oC changes occurred more slowly, while the most susceptible to oxidative changes was walnut oil.
