Chapter Summaries

Introduction: This chapter introduces the study, outlining its objectives and the significance of ensuring safe and high-quality mullet fish production. It sets the stage for the subsequent chapters, which delve into the literature review, methodology, results, and discussion of the research findings.

Review of Literature: This section provides a comprehensive overview of existing knowledge regarding HACCP principles, the chemical composition of mullet fish, and the effects of salting on fish quality and safety. It establishes a foundation for the research by exploring the various hazards associated with mullet fish processing, including chemical, biological, and physical hazards. The review discusses various quality criteria used to assess salted fish, laying the groundwork for the experimental methods employed in the study.

Materials and Methods: This chapter details the materials used in the study, including the fish samples, salt, containers, and equipment. It meticulously describes the dry-salting technique used for processing the mullet fish and outlines the analytical methods applied to assess the fish's physico-chemical, biochemical, and microbiological properties. The sensory evaluation methods used are also clearly explained. The detailed description of the methodology ensures that the study's results are reproducible and verifiable.

Result and Discussion - Part I: Hazards Analysis (HA) of raw mullet fish samples: This part presents a thorough hazard analysis of raw mullet fish samples. It details sensory, chemical, biochemical, and microbial hazards identified. The analysis likely includes data on proximate composition, pH, and microbial loads, providing a baseline assessment of the risks associated with using raw mullet fish. This assessment is crucial for establishing the critical control points in subsequent stages of the processing.

Result and Discussion - Part II: Salted mullet fish products during ambient storage periods: This section analyzes the changes in the organoleptic properties (appearance, odor, texture, taste, overall acceptability) and chemical composition (moisture, protein, lipid, ash, salt content) of salted mullet fish during storage. It also examines the biochemical indicators (pH, TBA value, TVB-N, TMA-N) and the microbiological changes (total viable count, halophilic bacterial count, yeast and mold count) during the 105-day ambient storage period. The detailed evaluation provides insights into the shelf-life of the salted product and the efficacy of the salting process in preserving its quality and safety.

Result and Discussion - Part III: Critical Control Points (CCPs): Based on the hazard analysis and the results of the storage study, this part identifies critical control points (CCPs) in the dry-salting process. These CCPs likely involve parameters such as dry-salting levels, storage temperature, and preliminary washing and packing procedures. The identification of CCPs is crucial for developing a HACCP plan to ensure the safety and quality of the salted mullet fish product. The section also details the monitoring steps needed to control these CCPs.
