Abstract :
[en] Co-production of chondroitin sulfate (CS) and peptides was realized from the liquid fraction of chicken sternal cartilage subjected to hot-pressure (HP) by membrane combination separation technology. Cartilage was liquefied via the HP treatment at 110 °C (0.07 MPa) and 120 °C (0.1 MPa) for 0.5 − 2.5 h, respectively. The optimized co-production procedure was as follows: enzymolysis temperature, 61.2 °C; the enzyme ratio of trypsin and papain, 1.3:1 (W/W); enzymolysis time ratio, 2:2 (h/h), under which the highest yields of CS and peptides were 18.85% and 67.99%, and the recoveries were 93.63% and 92.69%. The average molecular weight of CS sample was 67.79 kDa. CS sample was confirmed using agarose-gel electrophoresis, and the structure was analyzed by Fourier transform infrared spectroscopy, chromatography and nuclear magnetic resonance. Taken together, HP can be as a pretreatment method to liquefy cartilage for the industrial co-production of CS and peptides with eco-friendly. © 2019 Elsevier Ltd
