A comparative study on the raw chitin and chitosan yields of common bio-waste from Philippine seafood
Bio-waste materials from aquatic species are alternative sources of chitin and chitosan—high-value natural biodegradable and biocompatible polymers. More than 250,000 metric tons of shell, scale, and carapace waste are produced in the Philippines. An evaluation of the quality of raw chitin and chito...

Bio-waste materials from aquatic species are alternative sources of chitin and chitosan—high-value natural biodegradable and biocompatible polymers. More than 250,000 metric tons of shell, scale, and carapace waste are produced in the Philippines. An evaluation of the quality of raw chitin and chitosan yields from the bio-waste materials of Asian green mussel (Perna viridis), tropical oyster (Crassostrea iredalei), milkfish (Chanos chanos), tilapia (Oreochromis niloticus), and king mangrove crab (Scylla serrata) is needed for the sustainable sourcing. The mild extraction method done in this study showed significantly higher yields of chitin and chitosan for S. serrata and P. viridis (p = 0.001), with chemical structure confirmed through FTIR-ATR analysis. Elemental analysis showed pure extracts from S. serrata, P. viridis, and C. iredalei (N = 6.43–7.01%; DA = 98.7–104.1%).
