Abstract

Polymer coated Tin-free Steel (TPS) cans suitable for thermal processing of fish are now available in India. However, for successful use in thermal processing, the cans need to meet various performance criteria with respect to physicochemical properties. These cans were extensively tested for its suitability for processing different fish products. In this study, the physico-chemical properties such as sulphur staining test, delamination test, global migration test, air pressure test etc. were studied and the results compared with standards. Different fish products were processed at different Fo values and shelf life was determined by organoleptic test. The result indicates that the TPS cans locally available are suitable for thermal processing of fish and fishery products.
