씻어 놓은 쌀에 민들레 추출액을 각각 20, 30, 40 $^{circ}$Brix의 농도로 하여 쌀에 $5\%$를 첨가하며 10분 동안 5 mL/min의 속도로 분무하여 회전하며 코팅 쌀을 가공하였다. 대조군의 수분함량은 민들레 추출액 코팅 쌀보다 높게 나타났으며, D-40의 수분함량이 가장 낮았다. 색차계 측정값인 L값, a값은 코팅 수준이 증가할수록 낮아졌고 b값은 증가했으며, 밥을 지은 당일과 저장 2일 모두 같은 경향을 보였다 민들레 코팅 수준이 높은 쌀가루에서 DSC 호화 개시 온도는 높게 나타났으나 호화 정점 온도는 낮게 나타났다. 텍스쳐 측정결과 코팅 수준이 높아질수록 경도, 부착성, 탄성, 응집성, 씸힘성, 검성이 증가했고, D-20이 가장 바람직하게 평가되었으며 저장 2일 후도 같은 경향을 보였다.
Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 $^{circ}$Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 $^{circ}$Brix of the dandelion concentration) resulted in better textural properties and sensory scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice coated with 20 $^{circ}$Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 $^{circ}$Brix and $5\%$ respectively, in proportion to the total weight of raw rice.
