I was curious so did a quick Google search. Fresh insects looked to be about 21% protein and dried seemed to be in the low to mid 50's. Centra, what is the advantage of beetles as opposed to some other protein source that is more cost effective?
Below is what we are working on now. I am also Blue Tiger to keep documentation straight later. We have a bulk density problem and the drying is too slow. Working on expediting the drying process.
