The antioxidant capacity, phenolic acids profile, acrylamide contents and sensory quality of ginger cakes formulated on dark and brown rye flours according to the traditional formula (type 1 and type 2), and on the mixed white wheat flour with dark and brown rye flours due to the currently used formulation (type 3 and type 4), were studied. The antioxidant capacity of the ginger batters and cakes was investigated by cyclic voltammetry (CV) and against 2,2-diphenyl-1-picryhydrazyl radical (DPPH•). Phenolic acids profile was determined by HPLC whilst acrylamide by GC-MS method. The antioxidant capacity of traditional ginger cakes determined by CV and DPPH assays was higher when compared to those formulated on white wheat and rye mixed flours. All types of ginger cakes showed higher antioxidant capacity and phenolic acids content in relation to the respective batters. The higher content of acrylamide by 42 and 24% was noted in traditional ginger cakes of type 1 and type 2 as compared to that noted in ginger cakes of type 3 and type 4 (49 ± 4 µg/kg ). The overall sensory quality of traditional ginger cakes formulated on dark and brown rye flours (type 1 and type 2) was higher than those formulated on white wheat and rye mixed flours (type 3 and type 4). The results of this study indicate for the possibility of modulation of the sensory and antioxidant properties of ginger cakes by the type and quality of flours in the formulation as well as by batter preparation and baking process.
