In summary, the chitosan coating solution incorporating an
active shrimp protein-lipid concentrate increased the lag phase and
inhibited the growth of microorganisms involved in shrimp
spoilage. These results were reflected in the biochemical indices
determined in shrimp muscle. The composite chitosan coating was
imperceptible from a sensorial point of view and prevented black
spot development. Then, this coating could therefore be useful for
preserving shrimp quality during chilled storage with a shelf-life
extension in shrimps of about 5 days.
