| Summary: | The presence of gelatin is not limited to food products but has also been found in
pharmaceuticals. Most dental materials available in Malaysia are imported from other
countries and might contain gelatin which is a protein derived either from porcine, bovine or
other animal sources. Authentication of gelatin is crucial due to religious and health concerns.
Therefore, this study aimed to detect gelatin in dental materials using ATR-FTIR. Forty two
samples of dental material were purchased from dental suppliers and detection was done
using ATR-FTIR. The spectrum from each sample was compared against standard bovine
and porcine gelatin. Experimental dental paste containing bovine and porcine gelatin at
concentrations of 5, 10, 15 and 20% were also prepared for quantification analysis. The
results showed that gelatin was present in nine out of forty two samples of dental materials
but the species of origin was not confirmed. Meanwhile, in the experimental bovine and
porcine dental paste, it was seen that as the concentration increased, the intensity of the
absorption of Amide group also increased. Thus, ATR-FTIR can be utilized as a reliable tool
to detect gelatin in dental materials and other pharmaceuticals. |
