Abstract
In this study, 58 pomegranate concentrate samples collected directly from the local producers were adulterated with 2 different corn syrup and beet sugar syrup at different rates as 5-50% (w/w). The spectra obtained by FTIR-ATR spectroscopy of authentic and adulterated samples were evaluated by PCA chemometric methods. PCA method was used to distinguish the authentic-adulterated samples, select the spectral region and data reduction. The PCA-loading plot shows the most effective wavenumber to distinguish authentic samples from adulterated ones, which was determined to be in the range of 1200-900 cm-1. In the model created to distinguish the samples; it was found that PC1 and PC2 explained 83.1% of the total variance. Authentic and adulterated samples were successfully distinguished by PCA method. As a result, FTIR spectroscopy combined chemometric methods, can be used as a rapid and eco-friendly as alternative method for detection of in pomegranate concentrate.
