“…Issues associated with food quality and safety are increasingly becoming significant public concerns. , Particularly, concerns on perishable foods, for example, meat, seafood, and milk, are more outstanding as the growth of pathogens and spoilage microorganisms are easier to occur in these foods when exposed to relatively high temperatures (5–60 °C). , Ammonia and biogenic amines, which are mainly generated by protein decomposition, are known as the main metabolites during the spoilage of fish and seafood products. , By means of precisely detecting the level of these strongly odiferous compounds in perishable foods, one can readily evaluate the degree of food spoilage. Furthermore, based on this principle, many analytical methods such as spectroscopy, chromatography, , and electrochemistry have been established to directly measure the amount of these compounds in food.…”
