FOURIER TRANSFORM INFRARED (FTIR) SPECTROSCOPY STUDY OF SPINY LOBSTERS FROM VISAKHAPATNAM COAST, ANDHRA PRADESH, INDIA

Abstract

The purpose of the present study was to find out the functional groups present in the spiny lobsters (Panulirus homarus, Panulirus polyphagus and Panulirus versicolor) muscle tissue by using Fourier Transform Infra-Red (FTIR) Spectroscopy method. FTIR analysis was carried out by (Bruker, $\alpha$ ALPHA- t). The analysis of spectrum shows variations of functional groups in the muscle tissue samples at a Wavenumber region of 4000–550 cm–1. FTIR spectroscopic investigation showed the presence of distinctive peak values with different useful combination of functional groups, which were carbonyl group, alcohol, alkane, alkene, amine, amide, esters, ether, alkyl group and aromatics. The FTIR results exhibited the three species of spiny lobsters 12, 11 and 12 functional groups were identified. The highest peak of 3348.42 cm-1 in P. versicolor, 3395.48 cm-1 in P. homarus and 3281.37cm- 1 in P. polyphagus were observed in the FTIR spectra. The present study concluded that the tissue sample of P. polyphagus possessed strong functional groups, when compared with the P. homarus and P. versicolor.
