Polyphenol and vitamin C contents in European commercial blackcurrant juice products

Fortification of blackcurrant juice with crowberry: Impact on polyphenol composition, urinary phenolic metabolites, and postprandial glycemic response in healthy subjects

“…The identification of anthocyanins was based on MS spectra and literature. The anthocyanin profile of blackcurrant juice was dominated by rutinosides of delphinidin (M + = 611, rt = 11.9 min) and cyanidin (M + = 595, rt = 12.8 min) followed by the corresponding glucosides (M + = 465, rt = 11.3 min and M + = 449, rt = 12.3 min, respectively) which agreed with previous studies on blackcurrant juices (Landbo & Meyer, 2004;Mattila et al, 2011). Rutinosides of petunidin (M + = 625, rt = 13.6 min), peonidin (M + = 609, rt = 14.5 min), and pelargonidin (M + = 579, rt = 13.8 min) were tentatively identified as minor anthocyanins which also agreed with earlier studies on blackcurrant anthocyanins Ogawa et al, 2008;Wu et al, 2004).…”

“…In the basic blackcurrant juice, the measured content of total flavonols (5.25 ± 0.20 mg/100 g) was in close agreement with the recent study on commercial blackcurrant juices, where the contents varied from 0.6 to 7.6 mg/100 mL among different brands (Mattila et al, 2011). The quercetin content was doubled and the total flavonol content nearly doubled in the fortified juice compared to the basic juice.…”

“…Polyphenols and terpenes are the dominant majority of biologically active plant compounds with antioxidative and anti-inflammatory properties: these secondary plant metabolites may be nutritionally important and play critical roles in human health in the prevention of chronic diseases such as pulmonary inflammation, cancer, cardiovascular and neurodegenerative conditions (Donno et al, 2012b;Komes et al, 2011;Mattila et al, 2011;Tabart et al, 2012;Zhang et al, 2009).…”

“…Juices claiming to be high in antioxidants may have similar values to juices making no such claim [ 45 ]. In addition the manufacturing location of different juices can impact polyphenol content, as seen in blackcurrant juice products produced in Europe: higher levels of total polyphenols are found in blackcurrant juices from Germany and Poland than from Finland or the UK [ 46 ].…”
