Abstract :

In this study, the effects of pretreatment  irradiation power and time of microwave on total phenolic content , oxidative stability and the physicochemical properties of Cannabis oil, which included:  extraction efficiency, acidity values, refractive  and color index  were studied by a completely randomized design in the form of 3×3 factorial experiment with three levels of applied microwave irradiation power (180, 540 and 900 W) and three microwave time levels (90, 180 and 270 seconds) and three replications. The hemp seeds were supplied from animal feed store in Gonbad kavous city in early spring of 2017 and oils were obtained by using spiral press .The SAS software was used for data analysis. The results were showed that with increasing microwave power, the oil extraction efficiency, acidity, color index, oxidative stability and total phenol increased significantly (p< 0.01). Increasing the microwave time also led to an increase in the oil extraction efficiency, acidity, density, oxidative stability and total phenol. The pretreatment microwave had no significant effect on the oil refractive index. The maximum oil extraction efficiency was obtained from seeds which had a microwave power and time of 900 watts and 270 seconds respectively. The maximum oxidative stability (9.33 hours) was achieved when the applied microwave power and time were at their maximized levels. Overall, regarding the achieved results it can be concluded that the use of microwave in order to treatment of hemp seeds before oil extraction by cold press can improve the oil extraction efficiency and increase phenolic compounds.
