Abstract

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.

Abstract

Indonesia is a multicultural country and each ethnic group has different eating habits and basic taste preference of food. Gender is also known to have different preference in basic taste. The objective of this research was to study the effect of culture and gender on preference and detection threshold of sweetness and bitterness in Minang (West Sumatra), Javanese (Central Java) and Nusa Tenggara ethnic groups. The numbers of panelists were 90 first year undergraduate students in Bogor Agricultural University recruited from regional student organizations. The preference test was rankrating hedonic test in tea for sweetness and coffee for bitterness. Detection threshold experiment was conducted using 3AFC (3-alternative forced choice) method in standard solutions of sucrose and caffeine. Different culture of origin significantly affects preferences of sweetness in tea beverage. Panelists from Minang prefer higher level of sweetness compared to Javanese and Nusa Tenggara ethnic group. However, cultural differences did not affect preference to bitterness of coffee or bitterness. Overall, Indonesians tend to prefer tea beverage with high level of sweetness, and coffee with very low level of bitterness. Gender did not affect significantly the preferences of sweetness and bitterness, but detection threshold of female panelists was lower than that of male panelists. Women were more sensitive than man to detect sweetness and bitterness.
