Fifteen graduate students of the Department of Animal Science, National Chung-Hsing University, were trained as panelists. The panelists evaluated the appearance, color, ¯avor, texture, juiciness, and the overall acceptability of the warm balls using the preference test. A score of 1 indicated very low desirability in appearance, color, ¯avor, texture, juiciness and overall acceptability and a score of 7 very high desirability (Human et al., 1981; Raharjo et al., 1995).
