Fig. 4. Effect of black soldier fly larvae extract (SFL) obtained from larvae fed with food waste (FW), garlic peel added food waste (G), or hydroponic growth media added food waste (H) on lipid accumulation in 3T3-L1 adipocytes.

Cells were induced to differentiate into adipocytes in the presence or absence of samples. At day 8 of differentiation, intracellular lipid droplets were stained by Oil Red O and the retained stain were measured. Staining levels were given as relative percentage of C. ^a-iGroups with different superscript letters are significanly different, whereas same superscript letters mean no significant difference as revealed by Duncan’s multiple range post-hoc test (p < 0.05). B, non-differentiated untreated blank; C, differentiated untreated control.
