AB  - One of the key factors of supporting the rapidly expanding seafood product 
      industry in terms of quality control is the utilization of active packaging 
      materials. Microorganisms are primarily responsible for the perishability and 
      rapid disintegration of seafood. The incorporation of an inorganic compound, such 
      as silica-based diatomaceous earth (DE), and a metal oxide, such as zinc oxide 
      (ZnO), is proposed to develop active packaging materials with excellent 
      antibacterial activity, minimized fishy odor, and brittleness at subzero 
      temperatures. The mechanical, morphological, and physicochemical properties of 
      these materials were investigated. The results show that the addition of DE/ZnO 
      improved the antibacterial activity of high-density polyethylene (HDPE) samples 
      by up to approximately 95% against both gram-positive and -negative bacteria. 
      Additionally, it enhanced the Izod strength and stability at subzero temperatures 
      of the samples. The odor evaporation test revealed that trimethylamine can be 
      minimized in proportion to increasing DE/ZnO composite concentration. As a 
      result, the development of active packaging materials from DE/ZnO composites is 
      an emerging polymeric packaging technology for seafood products, wherein 
      packaging and seafood quality are linked.
