The application of ultrasound and microwave to increase

Microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE) are novel methods, which can reduce the extraction time. However, little information is known regarding the effect of UAE and MAE on the oil extraction from Moringa oleifera seeds as well as oil quality. This study aimed to evaluate the influence of MAE and UAE on oxidative stability and physicochemical properties of
