Quantification of Natural Sugars in Baby Food Products by MID FTIR Spectroscopy

No other food products focus consumer attention as those that are prepared for consumption by children. Of current interest are the natural and added sugar contents of processed baby foods and juices. Identification and quantification of natural sugars was investigated in baby food products by mid-IR Fourier Transform Infrared (FTIR) spectroscopy. Using Horizontal Attenuated Total Reflectance (HATR), neat baby food samples were analyzed without need for extensive sample preparation. By use of the HATR technique it was demonstrated that high sensitivity could be easily achieved without significant effect from water content. Factor space chemo-metric analysis was used to establish a robust method that allowed the confident measurement of sugar concentrations in these food products. The method was developed using a training matrix of three naturally occurring sugars, fructose, glucose, and sucrose. The method was confirmed using a verification matrix and was found to be readily applicable to the evaluation of sugar quantities occurring in commercial baby food products. Several commercial products were analyzed with this method and quantities of fructose, glucose, and sucrose were determined.
