Elemental Distribution Imaging on Edible Insects Using Micro-XRF

Edible insects have received attention as a possible solution as a supplemental source to reduce food insecurity because of their nutritional benefits such as protein, fat, and minerals. Micro-XRF can be used to understand the elemental distributions in insects non-destructively. In this application note, we carried out elemental map imaging on edible crickets using a HORIBA XGT-9000 X-ray analytical microscope and revealed the rich source of zinc in their jaws.
