| Résumé : |
Genipin, a derivative of the iridoid glycoside geniposide in the fruit of Gardenia jasmindides Ellis, is a naturally occurring protein crosslinking agent, which is not cytotoxic, and is beginning to replace glutaraldehyde as a fixative for biological tissues. This study was undertaken to evaluate the potential of iridoid compounds, in particular genipin, for use as tanning agents. The tanning effect of genipin on bovine hide powder was investigated. Parameters including the dosage of genipin, reaction time, pH and temperature of the tanning process were varied. The peak temperature (Tp) obtained by differential scanning calorimetry (DSC) of treated hide powder was used to evaluate the tanning effect. The results indicated that hide powder which had been treated with 5% genipin at pH - 7 and 35 °C for 24 h had a Tp of 79 °C. A secondary observation was that the tanned hide powder exhibited a dark blue color characteristic of the reaction of primary amines with genipin. A likely mechanism for genipin tanning is discussed. These results provide a new potential approach to chromium-free tanning for the leather industry. |
