Kinetics of microwave-assisted extraction of virgin coconut oil from solid coconut waste

Solid coconut waste (SCW) is a by-product of milk production which still contains virgin oil (VCO). This usually thrown away or left in fields. study aims to optimize the effects Microwave power (80–400 W), irradiation time (1–4 minutes), and solvent feed ratio (SF) (10–30 ml/g) on extraction VCO from SCW using microwave-assisted extraction. The optimized conditions were microwave power: 160 W, Irradiation time: 2.5 minutes, SF: 30 ml/g (15.93% yield). After extraction, characteristics such as matters volatile at 105 °C (0.193%), Free Fatty Acid (FFA) (1.38%), peroxide value (undetectable), insoluble impurities (0.0015%), saponification (258 mg/g), iodine (7.60), specific gravity (0.918), total plate count (0 CFU/ml) determined. second-order kinetic model described best (R2adj = 0.9994). method proves be more efficient than conventional method.
