Extraction of Volatile Pumpkin Oils through Cold Pressing versus Microwave Field -Features, Composition and Differences

This paper refers to the extraction of pumpkin seed oil using two processes, namely the extraction of volatile oils by cold pressing and hot pressing, and in the last process it will be pointed out the extraction of volatile oils using microwaves. Pumpkin seeds will be selected, each experimental sample will be weighed, and, from the observed samples thus obtained, we will notice the physicochemical properties of the extracted oil. To avoid the occurrence of phenomena that would affect the integrity of the microwave generator, the system will operate in pulses using an adjustable power magnetron.
