Abstract
Pomegranate juice is a good source of anthocyanins (delphinidin, pelargonidin and cyanine) and other phenolic compounds, including hydrolyzable tannins, such as punikalin, punikalagin and ellagic acid, and organic acids antioxidants. Unfortunately, up to 90% of pomegranate juice on the market today is a fake. In this article, we described the possibility of identifying the falsification of pomegranate juice less expensive grape juice.

Keywords: acidity, falsification, FT-IR spectroscopy, grape juice, pH, pomegranate juice, soluble solids, the absorption band, the spectrum
