Cooking characteristics of coated rice with water homogenate of citrus fruit peels (1% for rice) were investigated. The color of the coated rice both before and after cooking was dark yellow. The total content of carotenoids, hesperidin and naringin were 10.74, 2173.12 and 1468.40 ㎎% for citrus fruit peels, 0.46, 108.65 and 73.38 ㎎% for its water homogenate, 0.12, 21.73 and 14.62 ㎎% for coated rice, and 0.05, 8.67 and 5.87 ㎎% for cooked coated rice, respectively. Citrus fruits peel contained 94.22 ㎎% of asparagine, 24.88 ㎎% of methionine, 19.64 ㎎% of alaniue, and 15.37 ㎎% of r-aminoisobutyric acid as the majority free amino acids, accounting for 70% of the total free amino acids present. Total free amino acid content of the cooked coated rice increased by 15% compared to those of cooked uncoated rice. The majority of minerals in the citrus fruit peels were K and Ca, accounting for 86% of total minerals present. The mineral content of cooked coated rice was generally higher than that of the cooked uncoated rice. The cooked coated rice showed comparable hardness, gumminess and brittleness, but higher cohesiveness and springiness than the cooked uncoated rice. There were no differences in sweet and bitter taste between the cooked uncoated and coated rice. However, the cooked coated rice showed higher sensory scores for color acceptability, savory taste and overall acceptability than the cooked uncoated rice.
