Abstract: Lona ilish is a traditional salt fermented fish product widely consumed in Bangladesh and Northeast parts of India. It is prepared exclusively from Hilsa, Tenualosa ilisha (Ham-Buch, 1822), a high fat fish. Biochemical composition of market sample of lona ilish has been studied. The moisture, salt and pH of the product have been estimated as 54%, 15% and 5.66%, respectively. The product is stable when remains immersed in brine at ambient temperature. Lowering of water activity due to osmotic action of salt as well as effect of salt on spoilage bacteria are presumed to be the reasons behind this salt fermentation technique. High peroxide value is the indicative of lipid peroxidation but, however, did not impart any undesirable rancid taint to the product. The bacterial flora comprised of Micrococcus and Bacillus species. Lack of scientific study to standardize the methods, use of poor quality raw material fish, improper salting, inadequate fermentation period as well as adulteration in the process, etc. are some of the reasons for gradual deterioration of the quality of lona ilish.
