Table 2 shows the summary of characteristics of
BARA-KOJI and MOCHI-KOJI. In the process of BARAKOJI
fermentation, Aspergillus strains which had been
stocked inoculated artificially. MOCHI-KOJI was
fermented by environmental microorganisms under an
open-system. MOCHI-KOJI consists of many kind
microorganisms such as fungi, yeast, and some bacteria.
Generally, Rhizopus strain is the principal microorganism
of MOCHI-KOJI. For this reason, the fermentation period
of MOCHI-KOJI fermentation is 4-30 days. In contrast,
the fermentation period of BARA-KOJI fermentation is
1‒3 days. Therefore the quality of BARA-KOJI is stabler
than MOCHI-KOJI.
