Abstract The effect of black garlic powder on the quality of spent duck meat nuggets during storage was investigated. This study used a completely randomized design with 4×4 factorial. The first factor was black garlic powder (0%, 1%, 2%) and 200 ppm Butylated hydroxytoluene then the second factor was the storage period (0, 10, 20, and 30 days) in refrigerator temperature. Physical quality, chemical quality, antioxidant activity, and total plate count (TPC) data were collected and analyzed using analysis of variance. Sensory quality data were collected and analyzed using the Kruskal–Wallis test. The results showed that the addition of 2% black garlic powder significantly increased (P<0.01) the color redness (a*), total phenol, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) inhibition. However, it decreased (P<0.05) the pH, lightness (L*), peroxide value, TPC, color, aroma, and acceptability. Storage time increased (P<0.05) was decreased the pH, L*, a*, tenderness, protein, total phenol, and DPPH inhibition but increased (P<0.01) the yellowness (b*), peroxide value, and TPC. The addition of 1% black garlic powder was recommended to increase the spent duck meat nugget quality during storage without decreased the sensory quality of nuggets.
