In this study, HCl and H2SO4 were used to compare the best conditions for producing glucosamine from the dry chitin of shrimp shells. The results showed that for HCl hydrolysis, the most favored conditions were 12 M, 80 °C, 2 hours, and a chitin-to-acid volume ratio of 1:20, whereas, for H2SO4 hydrolysis, the most favored conditions were 6 M, 90 °C, 5 hours, and a chitin to acid volume ratio of 1:20. HCl produced pured glucosamine with a higher yield than H2SO4. Additionally, our findings indicated that glucosamine could be detected using a UV detector with a weak signal, whereas we recommended using an RI detector for a comparably stronger signal. Our production maximum yield of 283.9 ± 13.8 mg Gln g−1 chitin from HCl hydrolysis was comparable to that of other studies, with a comparison between using HCl and H2SO4 being highlighted.
