Daftar Isi:
- Tumpi-tumpi is a traditional food from South and West Sulawesi (ethnic Bugis-Makassar) using fishas raw material. The quality parameters of tumpi-tumpi, especially in terms of oil absorption, color andtexture were affected by the condition of the frying process (including the percentage of coating materials,temperature and frying time). This study was aimed to assess the production technology of the tumpi-tumpithrough frying process optimization of deep fat frying using Design Expert 7.0® software with ResponseSurface Methodology (RSM) Box-Behnken Design producing an optimal response. The results showed thatthe response of color (L value, ohue) and texture (hardness, cohesiveness) of tumpi-tupi were significantlyinfluenced by the percentage of coating materials as well as frying temperature and time. The optimizationusing software Design Expert 7.0® with RSM Box-Behnken produced the optimal processing formula of1.5% coating materials, 150oC frying temperature and 30 s frying time produced the tumpi-tumpi withproperties as follows: 62.25 of L (lightness) value indicating a bit light, 78.73 of ohue indicating yellow redcolor, 15407.60 gs hardness reflecting moderat hardness and 0.51 g/g cohesiveness impressing slight chewy.
