Synchrotron x-ray reveals microstructure in extruded insect flour

Hey Planet sells protein products based on insects. Through a collaboration with specialists in advanced characterization at the Danish Technological Institute, the company has investigated the microstructure of the extruded protein in great detail using synchrotron X-ray imaging.

In recent years, many new foods are being developed as sustainable alternatives to products such as beef and pork. Here, insects are a promising protein source that can be farmed vertically and with much lower energy consumption and CO₂ emissions. For insect protein to easily be included in a typical diet, it is important that it is processed to have a texture and mouthfeel that consumers enjoy.

Hey Planet is a company that sells a wide range of insect-based, protein-rich products. They use powder from the tiny buffalo beetles, which have a nutty flavor and a high content of quality protein. The product is extruded into an airy result that can easily absorb water and be incorporated into cooking with exactly the right consistency and mouthfeel.

Imaging can ensure successful upscaling

Through a collaboration with the Danish Technological Institute, Hey Planet has investigated the microstructure of the extruded protein in great detail using synchrotron X-ray imaging.

- The images can help clarify which structure provides the best properties and how it is linked to the processing parameters of the extrusion, explains Hanna Leemreize, Senior Specialist at the Danish Technological Institute.

In this way, imaging can be used to ensure a successful upscaling of protein production.

he Danish Technological Institute was very professional, deliveries were on time, and the results made it possible for us to ensure a successful upscaling of our production. Great service.
