Fresh bilberries were processed into sugar and sugar-low jams at high temperatures (90, 95, 100 and 105 �C) in order to follow degradation of total and individual anthocyanins. The greatest reten-tion of all examined compounds was observed in sugar-low jam prepared at 90 �C for 5 minutes, while the greatest loss was detected in sugar jam prepared at 105 �C for 30 min. Cyanidin-3-galactoside and cyanidin-3-glucoside were found to be the most stable, while delphinidin-3-arabinoside and
