Notes:
The main nonvolatile acids in the press juice of the northern crowberry, Empetrum nigrum ssp. hermaphroditum (Hagerup) Böcker were isolated with ion-exchange resins and analyzed as TMS-derivatives with glass capillary GLC and MS systems. The titrimetric acidity of the juice was only 43 mekv · 1−1 (titrated from pH 3.7–8.1) and the total content of the analyzed acids was 8.1 g · 1−1. The proportions of the acids were: Quinic acid 60%, malic acid 31%, citric acid 7%, and phosphoric acid 1%. Traces of glyoxylic, benzoic, and shikimic acids were found. Over 99% of the detected acids were identified.
