Lemon juice improved color acceptance of aronia (Aronia melanocarpa) pound cake by copigmentation.

ABSTRACT: Anthocyanins can be changed into dark purplish color during pound cake preparation due to high temperature and alkaline baking soda, which lowers color acceptance by consumers. To stabilize a red color of anthocyanins in pound cake enriched with aronia (Aronia melanocarpa) powder, lemon juice was added to contain final concentrations of 0, 1, 2, and 3% (w/w) in the pound cake, which were assigned as control, PL1%, PL2%, and PL3%, respectively. As lemon juice amount increased, redness (a^*) and sensory color perception as well as overall acceptance were enhanced, whereas hardness, gumminess, and chewiness decreased in texture profile analysis. In a model system, the addition of lemon juice to aronia solution caused bathochromic shift and hyperchromic effect in UV-Vis absorp
