Abstract

The use of second derivative method (2D) in the FTIR spectroscopy data processing is often done with the use of a large number of scans. The use of a large number of scan makes greater operating expense, it is not expected. Therefore in this study will be assessed the quality of 2D infrared characteristic spectra pattern of type B gelatin from porcine and bovine bones from spectral data with low scan. This study is part of efforts to find halal food identification methods, especially gelatin, in fast, accurate and economical.

Samples used were of type B gelatin from porcine and bovine bones are prepared in the laboratory, replication is of 10 data respectively. Infrared spectral data were collected using a Varian 1000 FTIR spectrometer in the wavenumber range 4000-700 cm-1, a resolution of 4 cm-1, scan 20. The second derivative used Fourier techniques.

The results showed that the 2D infrared characteristic spectra pattern of type B gelatin from the porcine and bovine bones that appear in the wavenumber of 730-740 cm-1 and 1030-1080 cm-1 can still be identified even though the pattern is clearly disturbed by the appearance of noise. Amplitude of the second derivative curve of value less than 0.01% T/cm-2 determined as a noise.
