ABSTRACT
The unclear effects of microwaves, as a greener alternative to hot air, on sensory perception, aroma, and hazardous components of sesame oil were investigated. Microwaves (900 W, 6-10 min) created more seed porosity and cell destruction and facilitated more γ-tocopherol release in sesame oil (349.30-408.50 mg/kg) than 200 °C, 20 min hot air (304.90 mg/kg). Microwaves (6-10 min) generated more aromatic heterocyclics (42.40-125.12 mg/kg) and aldehydes (5.15-2.08 mg/kg) in sesame oil than hot air (25.59 mg/kg and 1.34 mg/kg). Microwaves (6 min) produced sesame oil with a stronger roasted sesame flavour, and weaker bitter and burnt flavour than hot air. Microwaves reduced harman (≤775.19 ng/g), norharman (≤1,069.99 ng/g), and benzo(a)pyrene (≤1.59 µg/kg) in sesame oil than hot air (1,319.85 ng/g, 1,168.40 ng/g, and 1.83 µg/kg). Appropriate microwave is a promising alternative to hot air in producing sesame oil with a better sensory profile, more bioactive, and less carcinogenic components.
