Abstract
The invention discloses a modified chitosan-LZM-CA composite antibacterial cling film optimized by response surface methodology and the preparation method and application thereof, relates to the technical field of food packaging materials. The invention provides freshwater crayfish as the research object, and adopts the modified chitosan, lysozyme (LZM), a good film-forming material carrageenan (CA) as the composite antibacterial cling film materials, and through the response surface experimental design to determine the best ratio of modified chitosan-LZM-CA composite antibacterial cling film. Furthermore, the TVB-N value and the change value of the total number of bacterial colonies of the freshwater crayfish with the composite antibacterial cling film during refrigeration, can be regarded as indicators to examine the preservation effect, providing a theoretical basis of the chitosan composite film preservation technology development and application for freshwater crayfish and other aquatic products.
