Abstract
This study was carried out to investigate the quality characteristics of fried fish paste prepared with different amounts of squeezed Aronia melanocarpa juice. Squeezed Aronia melanocarpa juice (AMJ) was incorporated into fish paste at different levels (containing 2, 7, and 12 g of Aronia melanocarpa juice in 2 AMJ, 7 AMJ, and 12 AMJ, respectively) based on the total weight of water. Sugar contents and total acidity increased with increasing AMJ content. With increasing amounts of AMJ in fried fish paste, L value inside and on the surface decreased, a value increased, and b value inside decreased, whereas b value on the surface increased. pH decreased with increasing levels of AMJ. As the result of textural properties, folding test in all samples showed that AA means good flexibility. The strength, hardness, and chewiness of fried fish paste with AMJ increased while cohesiveness was not significantly different. Total polyphenol contents increased with higher levels of AMJ. DPPH radical scavenging activity was significantly higher than those of the control. In the sensory evaluation, fried fish paste containing 7 AMJ received the highest score than both the control and other samples.
