- Abstract
Anthocyanins are secondary metabolites of plants, distributed in vacuoles in the form of glycosides or acyl-glycosides. These natural pigments have shown diverse physiological effects based on their strong antioxidant properties. Epidemiological studies have shown a positive link between the consumption of anthocyanin-rich foods and reduced risk of cardiovascular, cancer or other age-related diseases. The aim of the present paper was to evaluate the level of total anthocyanins in wild and cultivated black currants (Ribes nigrum) from two different growing area in Romania. Quantitative determination was performed by the pH differential spectrophotometrical method. Wild black currants showed an increased total content of anthocyanin, expressed as cyanidin-3-O-glucoside equivalents, compared to the cultivated ones. Also, the study examined the influence of long-term cold storage of plant materials (freezing) upon anthocyanins content. The results showed an increase in anthocyanin content during long-term storage at -18°C in both investigated samples (11- 52%). The results may be of interest for food manufacturers, as any processing method may influence the content and composition of these pigments and consequently their health benefits.
