Abstract

Objective: The aim of this research to design lard detection using FTIR spectroscopy combined Partials Least Square (PLS).

Methods: Development of analysis method of lard in CPO oil using FTIR combined PLS to quantification of lard in CPO oil. Data processing in this study is looking for correlation about actual value and FTIR predicted value. The good correlation will give the high R2 value and low Root Mean Square Calibration (RMSEC), and Root Mean Square error External Cross Validation (RMSECV).

Results: The results showed that The analysis method using FTIR for lard detection with combination of the fingerprint spectrum at wave number 1481-999 cm-1 with wave number such as 779-650 cm-1, 1749-1650 cm-1 and 2990-3045 cm-1. This research resulted good correlation about actual value and predicted value at combination of wave number 1481.22-999.05 & 1793.67-1650.95 with R2 value is 0.998. The detection error is lowest because it has a small of RMSEC and RMSECV value with 0.998, 1.291 % (v/v), 0838% (v/v) respectively.

Conclusion: The characteristic of lard in CPO oil can be detected at combination of wave number 1481.22-999.05 & 1793.67-1650.95 with R2 value is 0.998 and RMSEC and RMSECV value with 0.998, 1.291 % (v/v), 0838% (v/v) respectively.
