Effect of unidirectional freezing on lipid changes during storage of minced bream.

Summary

The objective was to determine how unidirectional freezing would affect the stability of lipids in minced fish after frozen storage. Minced bream (Abramis brama) were unidirectionally or conventionally frozen. Lipid content, composition and oxidation were analyzed after 3 and 9 months, and 2 years storage at -20 deg C. After 2 years frozen storage of bream minces, peroxide value was 15 times lower, fluorescence and absorbance 3 times lower in unidirectional meat minces than in conventionally frozen samples. Unidirectional freezing could reduce lipid oxidation in minced fish during frozen storage.
