OPTIMALISASI PROSES EKSTRAKSI KHITIN DARI CANGKANG KEPITING DAN UJI KUALITATIF

A study towards the influence of solvent concentration and temperature variations in extraction pocess of chitin from crab shell as well as its qualitative examination has been investigated in this research. The result showed that the concentrations for the optimum process of deproteinations using sodium hydroxide, demineralisation with hydrochloric acid and decolorisation by hydrogen peroxide were 3.5%, 1.5 N and 0.35% respectively. their best extraction temperatures were 85oC for deproteinations, 35oC for both demineralisation and decolorisation processes. These optimum extraction conditions represent the need for a suitable reactor design allowing sequential acid-base treatments. futher upscaling effort may be required.
