Abstract
|
|
|
In order to utilize edible insect larvae as a functional material, the antioxidant components and activities of Tenebrio molitor larvae extracts were evaluated. The total phenolic content of the extract by ethanol concentration (95%, 70%, 50%, water) of T. molitor larvae powder was the highest in the 50% ethanol extract at 459.23 ± 1.05 mg%, and the total flavonoid content was the highest in the water extract at 19.86 ± 0.69 mg%. The DPPH radical scavenging activity of T. molitor larvae powder extract was the highest in 70% ethanol extract at 82.60 ± 0.00%, followed by water, 50% ethanol, and 95% ethanol extract. The ABTS radical scavenging activity in 50% ethanol and water extract was highest at 97.57 ± 0.16% and 95.33 ± 0.41%, respectively, with no significant difference.
Significantly, the reducing power was the highest in water extracts, followed by 50%, 70%, and 95% ethanol extract.
The results confirmed the antioxidant components and antioxidant activities of T. molitor larvae have been identified, indicating that it is worth using as a functional material.
