The objective was to evaluate the quality of soybean and canola oils packaged in PET bottles during their shelf life. Considering the limit for the peroxide value established by Brazilian legislation the soybean and canola oils were outside the specification at between 75 and 165 days of storage, respectively, that is, before the end of the period of validity established by the producer (6 months and 1 year, respectively). The sensory analysis revealed alterations in the oil attributes of ‘aroma’ and ‘taste’ at between 180 and 300 days of storage, although the grades did not reveal significant alterations or a reduction in the acceptance of the products. The results obtained indicate that the physico‐chemical quality parameters of soybean and canola oils produced in Brazil are outside the specification before the end of the validity period declared by the producers, the critical parameters being the peroxide and acid indices.
