Fourier transform infrared spectroscopy (FT-MIR) coupled with chemomet-ric methods has been applied for a fast and non-destructive quantitative determination of the adulteration of camel milk by cow milk. Mesurements were made on pure camel milk and that adulterated with varying concentrations of camel milk ( 1 “ 40 (wt/wt) in camel milk). A Partial Least Squares regression (PLS) method has been applied to predict added cow milk in camel milk based on modeling FTIR spectral absorption measurements. The fingerprint region at 3000“920 cm- were exploited for Partial Least Squares regression (PLS) without pretreatment and with different pretreatment ways (Gap Segment Derivatives Savitzky-Gloay Derivatives Noris Gap Derivatives and Standard Normal Variate). The obtained successful results (3.8 of relative error in the prediction) demonstrated that FT-MIR joined with chemometrics could be used as a rapid and non-destructive method for authentication of camel milk.

Abstract

Fourier transform infrared spectroscopy (FT-MIR) coupled with chemomet-ric methods has been applied for a fast and non-destructive quantitative determination of the adulteration of camel milk by cow milk. Mesurements were made on pure camel milk and that adulterated with varying concentrations of camel milk ( 1 “ 40 (wt/wt) in camel milk). A Partial Least Squares regression (PLS) method has been applied to predict added cow milk in camel milk based on modeling FTIR spectral absorption measurements. The fingerprint region at 3000“920 cm- were exploited for Partial Least Squares regression (PLS) without pretreatment and with different pretreatment ways (Gap Segment Derivatives Savitzky-Gloay Derivatives Noris Gap Derivatives and Standard Normal Variate). The obtained successful results (3.8 of relative error in the prediction) demonstrated that FT-MIR joined with chemometrics could be used as a rapid and non-destructive method for authentication of camel milk.
