Authenticity assessment of lingonberries (Vaccinium vitis-idaea) based products

Original language description

Lingonberries (Vaccinium vitis-idaea) represent a valuable source of bioactive compounds, especially polyphenols. The phytochemicals contained in lingonberries have been shown to have a positive influence on human health due to their significant antioxidant anti-inflammatory effects. For this reason, lingonberries are used in a number of different forms in the human diet: fresh, frozen, dried or in the form of tea or food supplements for Urinary Tract Infection (UTI) prevention. Recently, fraud suspicion on lingonberries-based products has been reported; Vaccinium vitis-idaea berries are partially or even totally replaced by less valued Cranberries (Vaccinium macrocarpon) grown mainly in North America. Although PCR methods may provide solution, these are not available in routine laboratories focused on food analysis. On this account, alternative analytical strategies have to be searched. In this study, metabolomic fingerprinting employing instrumental platform consisting of ultra-high performance liquid chromatography coupled to high resolution tandem mass spectrometry (HPLC-HRMS/MS) has been investigated. The unsupervised pattern recognition techniques, PCA and supervised pattern recognition techniques, PLS-DA and OPLS-DA, revealed significant differences between components in prepared extracts of lingonberries and cranberries. Clear clustering was found for both polar and non-polar extracts in positive and negative ionization modes. Anthocyanins, especially glycosylated peonidins (peonidin 3-O-glucoside, peonidin pentose) and phosphatidylcholines were identified as markers responsible for lingonberries and cranberries differentiation.
