Abstract

Leather jacket is the most popular fashion clothes made of garment leather. Garment leather generally derived from cattle, goat, sheep or pig skin. Muslim countries, including Indonesia, prohibit (haram) the products that derived from pig materials. If there are no labels on these products the costumers unable to find out the raw materials in leather products. Several techniques such as HPLC, PCR, GC-MS, electronic nose, and FTIR spectrophotometers have been carried out to distinguish the raw materials. The FTIR method is regarded as being affordable and simple to utilize. This study aims to evaluate the FTIR method coupled to chemometrics to distinguish the raw materials in leather garment. Lipid extracts derived from the various raw skin and leather garment were scanned using an FTIR spectrophotometer at 4000–450 cm-1 . There is the differentiation of spectral in two range of wavenumbers (3000-2800 cm-1 and 1200-1000 cm-1 ). The FTIR spectroscopy coupled to chemometrics can distinguish pig skin, sheep skin, pig garment and sheep garment through specific peaks in infrared spectra. This can be used as an initial analysis on determining the existence of skin adulteration in leather garment.
