Chitosan (CH1, 1% w/w solution) was used for producing chitosan film and used for glazing skinless pink salmon fillets. The rheological properties of chitosan solution, and mechanical properties and gas (oxygen, carbon dioxide and nitrogen) permeability of the chitosan film were evaluated. The effect of chitosan (CHI, 1% w/w solution) glazing on the quality of skinless pink salmon fillets after eight months frozen storage was determined. The theological study showed that CHI exhibited pseudoplastic and viscoelastic characteristics. The glass transition temperature (T-g) for the chitosan film was observed at 80.23 degrees C. The oxygen, carbon dioxide, nitrogen and water vapor permeabilities of the chitosan film were 5.34 x 10(-2) (cm(3) /in day atm),. 0.17 (cm(3) /in day atm), 0.03 (cm(3) /in day atm), and 2.92 x 10(-10) (g water m/m(2) Pa s), respectively. Fillets glazed with CHI solution exhibited significantly (P < 0.05) higher yield and thaw yield than the lactic acid-glazed (LA) and distilled water-glazed (DW) fillets, although these fillets all had similar moisture content after thawing. Chitosan, DW, and LA glazing delayed lipid oxidation in skinless pink salmon fillets after eight months frozen storage. (c) 2007 Elsevier Ltd. All rights reserved.
