Course description

Evaluating seafood quality is a critical process that ensures the safety, freshness, and market value of fish and seafood products. This course explores the biological, chemical, sensory, and instrumental methods used to assess quality throughout the supply chain—from harvest to consumer. You’ll learn how species variability, muscle composition, spoilage indicators, and environmental contaminants influence freshness and safety. Special attention is given to sensory analysis, EU grading, and tools like QIM, K-value, TVB-N, and VIS/NIR spectroscopy. Modern technologies such as electronic noses, NMR, and image analysis systems are also covered. The course highlights both traditional and emerging approaches used to monitor texture, color, odor, and chemical changes in fish. Practical applications and real-world challenges are examined, with emphasis on scientific, regulatory, and industry perspectives. By the end of this course, you'll understand the factors that define seafood quality and how to measure and interpret them using integrated methods. This knowledge is essential for professionals in seafood processing, inspection, product development, and quality control.

What you’ll learn

  • How to define and assess seafood freshness and spoilage
  • The role of sensory analysis, EU grading, and QIM systems
  • Chemical indicators such as TVB-N, TMA, DMA, and K-value
  • Common biological hazards in seafood and their health impact
  • Application of modern tools like VIS/NIR, NMR, and e-noses
  • Evaluation of seafood muscle structure, fat content, and vitamins
  • Key visual, physical, and microbiological quality traits
  • Regulatory standards and best practices in quality control
