Development of a process for canning fresh water fish rohu (Labeo rohita)

Results of experiments conducted to work out a process for canning fresh water fish rohu (Labeo rohita) from culture sources are presented. In order to impart a proper firm texture to the meat cold blanching the skinless boneless meat in 15% brine containing 0.25% calcium chloride was found necessary. Increasing the concentration of calcium chloride beyond 0.25% resulted in impairing the quality of meat, the texture becoming more fibrous and the flavour being adversely affected. Other firming agents tried did not yield any beneficial effect. The meat so blanched yielded a good product when canned in natural style.
