3.2.1.1.Preparation of raw material for canning
Preparation of raw materials for canning includes steps such as cleaning, washing, sorting, dressing, trimming, size cutting, mixing, mincing, brining, blanching, precooking, shucking, frying, smoking and grading.

If the frozen fish is used for canning, thawing is an important step. Thawing is a process of converting solid ice to water in a frozen fish. Thawing is done either in air or in running water till all ice of the fish melts.

If the fresh fish is used for canning it should be chilled immediately. It is important to keep the fish in chilled condition during all pre-processing operations.
