Abstract:

The technology for the chitin extraction from the residue of Dactylopius coccus Costa cochineal dye process was studied. The results showed that the optimal conditions for protein removal are 1.0 mol/L NaOH at 80 ℃ for 2 h, and those for inorganic salt removal are 1.0 mol/L HCl at 50 ℃ for 60 min.

Key words: cochineal, chitin, protein, inorganic salt
