Comprehensive information was gathered on acid and sugar concentrations of six wild berries (bilberry, lingonberry, cranberry, cloudberry, red raspberry and black crowberry) and five cultivated berries [blackcurrant, whitecurrant, redcurrant, gooseberry (red) and strawberry], all grown in Finland. The main acids of the berry juices were invariably citric and malic acids, even though their concentrations varied widely from one berry to another (2.9-16.2 and 3.3-24.7 g l -1 , respectively). In addition, juices of lingonberry, cranberry, cloudberry and black crowberry contained benzoic acid (0.1-0.7 g l -1 ). The main sugars of the investigated berry juices were fructose (18.0- 57.2 g l -1 ) and glucose (22.2-50.0 g l -1 ). Most of the berries contained also sucrose (0.2-5.1 g l -1 ). The data enable equivalent comparison of Nordic berries and underline the wide variation in their acid and sugar content and so the possibilities for production of numerous organoleptic profiles. |
