Chitin quantitation (as glucosamine) in food raw materials by HPLC–C18-DAD with off-line derivatization
Original language description
This HPLC method is suitable for chitin quantitation (reported as glucosamine) in food raw mate- rials like insects (mealworm larvae, crickets), shrimps, mushrooms and fungi in a research (non- routine) laboratory using a C18 column with HPLC system < 600 bar with UV detection capability (at 265 nm). To remove interferences, the sample is defatted (Soxhlet) and deproteinized (by al- kali) prior to acid hydrolysis in 6 M HCl. A five-point linear calibration (5–100 μg/mL) is used. The use of fluorescence detection (λex = 260 nm, λem = 350 nm) is also possible with this method. • 18 min HPLC run time • LOD = 0.05 μg/mL and LOQ = 5 μg/mL
