ABSTRACT
This study was performed to develop a liquid flavoring material from Tenebrio molitor larva by using Aspergillus oryzae. T. molitor with 1% A. oryzae for 48 hours yielded the highest protease activity. Different salt concentrations and rice flour addition affected the fermentation characteristics for 90 days. LN (low salt, rice flour non-addition) yielded high protease activity, and total nitrogen and amino-type nitrogen contents. LN showed Glu accounting to 15.16% of the free amino acids and yielded high scores of sweet and savory taste, and overall acceptance after 90 days. Rice flour addition group showed high content of total and reducing sugars with high amylase activity, however, low salt concentration had more effect on sensory acceptance than rice flour addition had (p<0.05). All samples had total acidity <1% and LN (90) showed the highest browning index and aroma intensity, as noted from maillard reaction, as well as good sensory acceptance.
