Organic acids (oxalic, malic, citric and succinic) of different raspbe
rry cultivars ('Boyne,' 'Festival,' 'Killarney' and 'Prestige') grown
in Maine were determined using Hi Performance Liquid Chromatography (H
PLC) during a three year study. Organic acid profiles differed signifi
cantly among the raspberries depending upon the cultivars. Weather con
ditions, i.e. temperature, percent of sunshine, and rainfall during gr
owing season had also a significant effect on the organic acid.
