RESULTS AND DISCUSSION
The fermented fishes in the present study exhibited after complete fermentation had moderately soft texture.
On the organoleptic point of view, these fermented products showed, good quality with a typical characteristics odour and desirable flavour.
Ngari stored at room temperature achieved the best quality as compared to others. Ngari at 40°C had slightly dark
colour and possessed pungent smell due to prolong storage at high temperature. However, there is not so much variation in the chemical composition of all the products.
In the present analysis, cholesterol content has a value of 3.90 mg/g at 20° C, 3.22mg/g at 40° C and 3.67mg/g at room temperature.
It is lower at higher temperature.
The food borne bacteria capable cholesterol, degradation especially in fermented foods.
B subtilis isolated from Korean traditional fermented flate fish, could produced a high level of cholesterol
oxides, which degrade cholesterol .
Sugar was greatly reduced after fermentation.
Carbohydrate in the form of soluble sugar might be absorbed by fungi present in the fishes for supply of
energy required for their general metabolism It might also related to the declined of fungi, especially the
Aspergillus sp. Ngari stored at 40° C, reduces the value
from 0.62 to 0.47mg/g.
