In this study we estimated shelf life of canned marinated hearts of artichoke (Cynara scolymus L.) which had the major sensory preference in color and flavor evaluated by a semi trained panel conformed by 15 judges. Also omega 3 and omega 6 content was determined (28.69 g/100g y 43.26 g/100g of fat respectively) which are within the limit approved by the World Health Organization. It was done the estimation of the shelf life by accelerated testing, the samples were incubated at 37ºC, 49ºC and 55ºC, evaluating the kinetic of deterioration of the fat in function of the peroxide index that followed a reaction of order zero. The temperature effect was evaluated with the equation of Arrhenius, and the activation energy was 96115.6 J/mol. At a storage temperature of 20 ºC, the estimation of shelf life was 892 days.
