The aim of the study was to evaluate the effects of turmeric supplementation on selected quality features, oxidative stability, and the safety of duck meat burgers. Four burger variants, namely I–control, no additive, II–with turmeric powder, III–with turmeric extract, and IV–with turmeric paste, were tested. The pH, WHC, colour parameters on the CIE L*a*b* scale, finished products’ shear force, TBARS index, and the total number of microorganisms were determined while performing sensory evaluations. Tests were carried out after 24 h, 6, 12, and 18 days of refrigerated storage (4 ± 2 °C). The addition of turmeric powder and paste significantly limited lipid oxidation processes in vacuum-packed duck meat burgers over an 18-day period. Although lipid oxidation processes accelerated after 6 days in all burger variants, burgers with powdered turmeric powder showed the lowest TBARS index values and limited total microorganism increases. Turmeric paste and powder additions resulted in decreased pH, increased water retention, and lighter colouration in refrigerated products. These additives were deemed acceptable during sensory evaluation. The most desirable aroma and taste, including juiciness, were in burgers with turmeric paste addition, while burgers with powdered additions were rated higher for their desired aroma and intensity of taste.
