Fermentation is an easy and safe means for
preservation of fish which involves various techniques.
Ngari (a fermented fish product) have a high consumer
acceptance and have contributed in many ways to the
diet of northeastern part of India. This indigenous
product is prepared from sundried P. sophore (Ham),
P. ticto (Ham) and Setipinna sp (Swainson) subjecting
to fermentation for five to six months in an eartherned
pot at room temperature. Because of its special flavor,
it is used as a compulsory item in daily curry
preparation (Sarojnalini and Vishwanath., 1988).
Nutritive value of such processed fish has been
reported to be high and also serves as a preservative
making the food tastier and easier to digest. Sometime,
processing tends to affect the nutritional value of food
products. The important factor which determines the
value of a fish product is its biological composition.
The desirable changes produced by the action of
microbes enhance the flavour improve the nutritional
value and extend the shelf life .
