Vaccinium macrocarpon (Cranberry)-Based Dietary Supplements: Variation in Mass Uniformity, Proanthocyanidin Dosage and Anthocyanin Profile Demonstrat…
2020
Vaccinium macrocarpon (syn. American Cranberry) is employed in dietary supplements (DS) with the aim to improve urinary tract well-being. This property is linked to the antiadhesion-activity of proanthocyanidins (PACs) against uropathogenic-bacteria. However, the current European legislation has been criticized for being weak and ineffective. Indeed, recent scientific works report mislabeled, contaminated, and adulterated supplements containing dangerous or unknown compounds, or sold at toxic doses. In this work, we analysed 24 DS that claim to contain cranberry, and to have a specific dosage of PACs. Our tests included the control of the good manufacturing practice according to the Europea…
Berry press residues as a valuable source of polyphenolics: Extraction optimisation and analysis
2018
Abstract Vaccinium genus berries (bilberries, blueberries, lingonberries, cranberries) are gathered in the wild as well as cultivated on an industrial scale for use in the food industry. Extraction of juices from these berries produces press residues (pomace) as a waste product. Berry press residues are an excellent source of phenolic compounds and have a potential of use as a polyphenol-rich material. The aim of the present study was to optimise the method of extraction of polyphenols (anthocyanins specifically) from berry press residues of American cranberry using the response surface method and to validate the optimal polyphenol/anthocyanin extraction conditions also for other Vaccinium …
