Silkworm pupae are by product derived from harvested cocoon. It is popular fried for consuming
due to its good taste and high protein content. To avoid the frying, microwave drying process is
interesting for health lovers. The objective of this research was to study the effect of microwave
power combined with hot air on drying kinetics of silkworm pupae. The microwave powers
of 143 270 323 and 394 watts were applied and combined with hot air at temperature of 60°C
with air velocity of 1 m/s. These were compared with drying alone at air temperature of 60°C.
The results showed that the increase in microwave power resulted in the higher drying rate
and higher than only hot air drying. For colour assessment found that microwave combined
with hot air drying provided lower lightness (L*), higher redness (a*) and yellowness (b*) than
that drying with only hot air. For the specific energy consumption, the best drying condition
of silkworm pupae is using microwave power of 323 watts combined with hot air. The drying
time and energy consumption could be reduced by 98.74 and 98.11% when compared to only
drying with hot air at 60°C.
