Antioxidant activities of black soldier fly, Hermetia illucens

ABSTRACT The purpose of this study was to determine the possibility of black soldier fly (Hermetia illucens) as a animal feedstuff.Insect resources have been widely recognized that it exhibits its own biological activity by whole body or its metabolicintermediates. To accomplish this, its general and biological activities were measured. The present study was conductedto compare antioxidant activity of black soldier fly larva, pupa and grasshopper by examining radical scavenging activ-ity using DPPH (2,2 diphenyl 1-picryl hydrazyl). DPPH radical scavenging activity was conducted on the EtOH,MeOH, H2O fractions of black soldier fly larvae. Results showed that black soldier fly pupa on the H2O fraction con-tained the highest DPPH radical scavenging activity among the samples. FRAP assay are more suitable methods to eval-uate antioxidant activity of black soldier fly extracts. Among the samples, the FRAP value showed higher antioxidantactivity in the extracts from black soldier fly pupa extract on H2O fraction. These results suggest that black soldier flylarva and pupa extract has antioxidant activity and its fractions can be utilized to develop functional feedstuff.Key words : Black soldier fly, Hermetia illucens, Antioxidant activity
