Determination of the freshness of meat products by HPLC

Abstract: In Japan, raw meat—particularly raw fish and shellfish—plays a vital role in traditional dietary habits. The freshness of fish is crucial for both taste and safety, as it deteriorates quickly after being caught. To ensure quality, a reliable and quantitative method for assessing freshness is essential. Freshness is typically categorized into several levels, with the initial stage defined by the K value, also known as the freshness index. This value reflects the condition of the fish immediately after it is removed from the hook, serving as a key indicator of its quality and suitability for consumption. Understanding and monitoring the K value helps maintain high standards in food safety and culinary excellence. By using this parameter, producers, processors, and consumers can make informed decisions about the quality of seafood before it reaches the table.
