Sugars and organic acids in clones and cultivars of arctic bramble and hybrid. Sensory evaluation of juices and jellies
Arctic bramble (Rubus arcticus L.) and its hybrid (Rubus arcticus L. nothosubsp. stellarcticus G. Larsson) are both cultivated in Finland. Sugars and major organic acids were analysed in several arctic bramble clones and cultivars (n = 19) and arctic bramble hybrids (n = 5) by gas chromatography. Th...
