I’m not vegan either, but do have to be really careful about stuff like this because I’m allergic to milk and meat/gelatine - so many beers and wines set off a serious asthma attack, because they are used in the filtering processes. So jelly babies are out for hypos, that kind of thing.
Interestingly, older formulations of black tattoo ink are made using bone char, so I have to make sure my artist uses vegan inks when I go for a spot of permanent mutilation, just in case being of mammal origin triggered an allergic reaction
Having said all that, I do think that we’ll be seeing insects more and more on the menu - a friend of mine who makes meat, vegan and fruit jerkies, also does a range of spiced, dried invertebrate snacks. The locusts and mealworms are awesome and a great source of protein. I love them
You can also grind them to make really good, high protein flour for baking. And biologically speaking, not much different to prawns.
