The oxidative stability of walnut oils to storage: observation of the influence of cultivar, heat and light : a dissertation submitted in partial fulfilment of the requirement for the degree of Bachelor of Science with Honours at Lincoln University

Abstract

The main aim of this study was to determine the effects of storage on the long-term stability of walnut oil. In order to achieve this, four main objectives were considered. These were as follows:

1. To determine the influence of cultivar variety on the stability of walnut oil. 2. To determine the influence of light on the stability of walnut oil by storing oils in the dark/light and utilising different bottle colours. 3. To ascertain the effect of heat on the stability of walnut oil by storing oils both at room temperature (24°C) and under accelerated high temperature conditions (60°C). 4. To determine the influence of time on the stability of walnut oil by storing the oil for four months under these various conditions and interaction.
