Abstract

This study was carried out to optimize coating process of the rice snack added with dried shrimp powder by using single extruder. A total of 8 independent variables were used for 4 independent variables of edible oil coating and 4 independent variables of seasoning coating. 4 independent variables for edible oil coating were set up as 10, 15, 20, 25 and 30% for the content of edible oil; 40, 50, 60, 70 and $80^{\circ}C$ for the tumbler temperature; 60, 70, 80, 90 and 100 rpm for the tumbler speed; 2, 3, 4, 5 and 6 min for the coating time. 4 independent variables for seasoning coating were set up as 2, 3, 4, 5 and 6% for the content of seasoning; 40, 50, 60, 70 and $80^{\circ}C$ for the tumbler temperature; 50, 60, 70, 80 and 90 rpm for the tumbler speed; 2, 3, 4, 5 and 6 min for the coating time. The characteristics of the dependent variables as coating yield and Breaking ratio of collet due to the condition changes of the independent variable was studied during process of edible oil coating and seasoning coating, respectively. As a results of this study, 20% of edible oil content, $70^{\circ}C$ of tumbler temperature, 80 rpm of tumbler speed, 4 min of coating time for process of edible oil coating, 3% of seasoning content, $60^{\circ}C$ of tumbler temperature, 70 rpm of tumbler speed, 3 min of coating time for process of seasoning coating were found to be the most preferable over other independent variables for the production of snack. In conclusion, it is necessary to set the independent variable in order to produce the high quality snack added with the rice as the main raw material and dried shrimp, edible oil and seasoning as the sub-materials.

마른새우가 첨가된 쌀 collet을 이용하여 편이 스낵을 제조하기 위하여 식용유코팅 독립변수 및 혼합조미분말코팅 독립변수 각각 4개(사용량, tumbler 온도, tumbler 속도, 코팅시간)의 조건변화에 의한 각각 2개의 종속변수(코팅수율, 파손율)의 특성을 조사한 결과를 요약하면 다음과 같다. 식용유코팅 시, 식용유 사용량을 10-30%로 조건을 변화하여 collet을 식용유코팅 할 경우, 코팅수율은 증가하다가 사용량 20% 이상일 때는 거의 비슷한 값이었으며, 파손율은 사용량이 증가할수록 감소하였다. Tumbler 온도를 $40-80^{\circ}C$로 조건을 변화하여 collet을 식용유코팅 할 경우, 코팅수율은 온도가 높아질수록 증가하다가 $60^{\circ}C$부터는 거의 일정한 값을 보였으며, 파손율은 온도가 높아질수록 지속적으로 증가하였다. Tumbler 속도를 60-100 rpm으로 조건을 변화하여 collet을 식용유코팅 할 경우, 코팅수율은 속도가 빨라질수록 증가하다가 80 rpm을 기점으로 거의 일정한 값을 나타내었으며, 파손율은 80 rpm 까지는 미미하게 증가하다가 90 rpm 부터는 급격히 증가하였다. 코팅시간을 2-6분으로 조건을 변화하여 collet을 식용유코팅 할 경우, 코팅수율은 시간이 경과할수록 증가하다가 5분 이상이 되면 다시 감소하였으며, 파손율은 4분까지는 미미하게 증가하다가 5분 이상이 되면 급격히 증가하였다. 혼합조미분말코팅 시, 혼합조미분말 사용량을 2-6%로 조건을 변화하여 식용유코팅 collet을 혼합조미분말코팅 할 경우, 코팅수율은 증가하다가 사용량 5%이상에서는 오히려 감소하였으며, 파손율은 사용량이 증가할 때 미미하게 증가하다가 사용량 4% 이상에서는 거의 일정한 값을 보였다. Tumbler 온도를 $40-80^{\circ}C$로 조건을 변화하여 식용유코팅 된 collet을 혼합조미분말코팅 할 경우, 코팅수율은 $60^{\circ}C$까지는 증가하였으나 $60^{\circ}C$이상에서는 오히려 감소하였으며, 파손율은 온도가 높아질수록 지속적으로 증가하였다. Tumbler 속도를 50-90 rpm으로 조건을 변화하여 식용유코팅 된 collet을 혼합조미분말코팅 할 경우, 코팅수율은 속도가 증가할수록 높아지다가 70 rpm을 기점으로 감소하였으며, 파손율은 속도의 증가에 따라 미미하게 높아지다가 70 rpm 부터는 급격하게 증가하였다. 코팅시간을 2-6분으로 조건을 변화하여 식용유코팅 된 collet을 혼합조미분말코팅 할 경우, 코팅수율은 3분까지는 증가하다가 4분 이후에는 감소하였으며, 파손율은 코팅시간의 경과에 따라 지속적이고 급격히 증가하였다. 따라서 식용유코팅은 tumbler 온도 $60^{\circ}C$ tumbler 속도 80 rpm 코팅시간 4분 식용유 사용량 20%, 혼합조미분말코팅은 tumbler 온도 $50^{\circ}C$ tumbler 속도 70 rpm 코팅시간 3분 혼합조미분말 사용량 3%로 각각 설정하여 스낵을 제조하는 것이 가장 바람직하다고 판단되었다.
