In the present study, the efficiency of the use of an enzyme (2% hemicellulase, raw material: water of 3: 1 and hydrolysis time of 24 hours) was evaluated to increase the yield of the moringa oil extraction with press expeller and the changes in the physicochemical and antioxidant characteristics of the oil, besides estimating the shelf life of the moringa oil without enzymatic treatment by accelerated methods. For the estimation of shelf life, samples of raw moringa oil were stored at temperatures of 40, 50 and 60 °C and the evaluation was made based on the peroxide index, degree of acidity and coefficient of extinction k232 and k270. The evolution of the four quality parameters was recorded every five days for a total time of 40 days and the characteristics of the virgin olive oil mentioned by the Codex Alimentarius were taken as reference. It was obtained a greater yield in the extraction of the moringa oil with previous enzymatic treatment and was found significant differences in the peroxide index and degree of acidity. It was determined that oleic acid was found to be higher in moringa oil (72%) and α-tocopherol being the greater isomer. In addition, it was determined that the moringa oil extracted with previous enzymatic treatment had a higher content of total polyphenols compared to the control moringa oil; however, no significant differences were found in the antioxidant capacity determined by The ABTS assay. The shelf life of the moringa oil was estimated to be 280 days for the peroxide index, 214 days for the extinction coefficient k232, 204 days for the extinction coefficient k270 and 222 days for the degree of acidity
