Recovering Carotenoprotein from Shellfish Waste

This study used autolysis and natural enzymes already present in shrimp and crab waste to break it down and recover carotenoprotein, a valuable compound rich in protein and astaxanthin. No harsh chemicals were needed, just the waste material's own enzymes doing the work. The study found that the ratio of shrimp to crab waste changed how much carotenoprotein could be recovered, which is exactly the kind of process detail that determines whether a waste valorization method is practical at scale or only works on paper.
