Résumé : |
We have investigated physical and chemical properties of fur and fur products for establishing scientific standards for evaluation of fur. In the present experiment, using mink and blue fox fur as the test samples, investigations were conducted on whether an indication of deterioration of fur properties by an artificial degradation treatment could be detected by amino acid analysis.
Light irradation to a degree so as to reduce physical properties of a fur led to a marked reduction in the cystine residues of the fur. Distinct reductions (20-50%) were observed with mink after irradiation for 100 hr, and with fox for 50 hr. Cystine content can possibly be used as a chemical standard for evaluating degradation by light. In that case, expression in a relative value to the valine content will be suitable. |
