Example 4

A Rancimat stability study was performed using the crude DHA canola oil and reference blend described in Examples 1 and 2, respectively. The method involved testing about 2.5 g of test material using the standard procedures for a Metrohm 743 Rancimat at 90° C.

The table below summarises the results obtained from these oils at 90° C. The experiments were performed in duplicate.
