摘　　要：An insight into chemical composition,nutritional value and potential health risk of increasingly popular bilberry and black chokeberry commercial juices was provided,based on HPLC-UV(anthocyanins and non-anthocyanin phenolics;patulin;hydroxymethylfurfural),AAS(minerals)and ICP-MS(trace elements)analyses.Delfinidin(in bilberry)and cyanidin glycosides(in bilberry and chokeberry)were the most abundantly present anthocyanins,chlorogenic acid dominated among non-anthocyanin polyphenols,while mineral composition revealed high K and desirable low Na content.A glass of blueberry/black chockeberry juice(200 mL)per day could provide up to 63.5/27.0 mg of anthocyanins,147.2/314.0 mg of polyphenols,almost 50%of Mg(the only mineral satisfying the requirement for a nutritional claim)and,in case of chokeberry,20%of Mn adequate intake.No health risk was observed related to any of the investigated toxicants.Despite indications of a possible benefitial role for health,observed compositional variations precluded positioning of berry juices as functional foods.The labelling could help specialist in nutrition and functional foods as well as health-conscious consumers seeking foods with reliable quantity of dietary valuable phytochemicals and minerals.Sufficiently characterised food has been one of the prerequisites for the approval of a health claim,along with sufficiently defined and substantiated claimed effect.
