A study is undertaken to examine the effects of the additional frozen blueberry powder and anthocyanin powder extracted from black beans to quality attributes of pound cakes. Frozen blueberry powder and anthocyanin powder extracted from black beans are being added to the flour at a ratio of 0.5, 1.5, 2.5, and 3.5% respectively. The antioxidant activity is highly correlated with the total phenolic and total flavonoids contents of frozen blueberry powder and anthocyanin powder extracted from black beans of pound cakes, respectively (r=0.8423, p<0.001 r=0.9449, p<0.001). The quality characteristics of the specific volumes decreased significantly with increasing substitution levels of frozen blueberry powder and anthocyanin powder extracted from black beans (p<0.01). The lightness significantly decreased with increasing frozen blueberry powder and anthocyanin powder extracted from black beans of pound cakes' crusts and crumbs (p<0.01). The hardness, chewiness and gumminess tend to reduce, while the cohesiveness increase in both powders. The consumer acceptability score for 0.5~3.5% of frozen blueberry powder and anthocyanin powder extracted from black beans pound cakes ranked significantly (p<0.01) higher than those of the other groups according to taste, flavor and overall preferences. These results show that frozen blueberry powder and anthocyanin powder extracted from the black beans are a good ingredient for increasing consumer acceptability and overall healthy. Key words: frozen blueberry powder, anthocyanin powder extracted from black beans, pound cakes, total phenol content, flavonoids content, quality characteristics
