Quality evaluation of red and white currant cultivars.
Quality of 7 red and 4 white currant cultivars was determined.The study was done in Dobele HPBRS, Latvia, in 2002 and 2003.Contents of ascorbic acid, total anthocyanins, soluble solids of fresh and frozen berries were analysed, and average berry weight, and number of flowers per cluster were evaluated.The most remarkable red currant cultivars were ‘Varshevicha’ and ‘Viksnes Sarkianas’ because of high anthocyanin (berries were dark red) and ascorbic acid contents, and ‘Rote Spätlese’ and ‘Rovada’ because of many flowers per cluster.Latvian ‘Viksnes Sarkanas’ had high berry weight and many flowers per cluster as well.Latvian’ Cirvja Piets’ had the largest berries and the highest ascorbic acid content from white currants, ‘White Dutch’ also had high content of ascorbic acid and ‘Viksnes Baltas’ – high berry weight.In total, only content ofascorbic acid changed significantly after frozen storage 18.2% loss in 2002 and 19.0% loss in 2003.The most stable ascorbic acid was in white currant ‘Cirvja Piets’ (13.6% loss) and currant ‘Viksnes Sarkana’ (4.15% loss).
