Statistical Tools to Optimize the Recovery of Bioactive Compounds from Marine Byproducts

What if fish bones, shells, and skins could be transformed into potent health-boosting compounds? Seafood waste is quietly becoming a goldmine—if we can find the perfect recipe to unlock it.

Every year, the seafood industry discards mountains of bones, heads, skin, frames, fins, shells, guts, and viscera. But these so-called byproducts are far from useless. Hidden inside them are valuable bioactive molecules—from omega-3 fatty acids to collagen, chitin, and carotenoids—that could fuel everything from nutraceuticals to biomedicine.

The challenge isn't just extraction; it's doing it smartly. Green technologies are strictly required, but their success hinges on getting the process parameters right. That's where statistics steps in. This review zeroes in on the statistical optimization strategies used to fine-tune extraction processes, ensuring efficiency, quality, and economic viability.

Researchers have focused on key variables like enzyme-to-substrate ratio, pH, time, temperature, and instrument power. By designing clever experiments and validating their effects, they can pinpoint the best conditions to maximize yields of long-chain polyunsaturated fatty acids, peptides, enzymes, gelatine, and more. It's a data-driven dance between science and sustainability—turning waste into wonder, one optimized run at a time.

Key Points

• Statistical tools optimize extraction of bioactive compounds from seafood byproducts.
• Key parameters: enzyme/substrate ratio, pH, time, temperature, and power.
• Focus on yield of fatty acids, collagen, chitin, vitamins, and carotenoids.
