We evaluated the characteristic odor substances in Asian carp meat, which are prevalent in the Great Lakes, to provide a foundation for resource utilization and removing its fishy smell. Three Mono Trap RCC18 adsorbents were used to extract samples. Volatile components were analyzed by gas phase‐olfaction‐mass spectrometry. The main odor‐active substances were identified by aroma extraction dilution analysis. The overall odor profile was analyzed by electronic nose. Overall sensory evaluation showed that metallic and grassy in Chinese carp were heavier than those in American. Trimethylamine, ketones, aldehydes, and alcohols were the main odor components in the two species. Flavor dilution factors indicated that hexanal (grassy), 1‐octen‐3‐ol (mushroom‐like), and 2,3‐pentanedione (milky) were important. Trimethylamine, 1‐pentene‐3‐ol, 2,3‐pentanedione, pentanal, 3‐methyl‐1‐butanol, hexanal, 1‐Hexanol, heptanal, 1‐heptanol, 1‐octen‐3‐ol, octanal, 2,3‐pentanedione. D‐limonene, nonanal, decanal, and naphthalene were the main flavor substances. The contents and intensities of volatile substances are generally higher in American than in Chinese silver carp.
Practical applications
The large numbers of American silver carp are problematic in the Great Lakes. Pollution of the water environment may cause contamination in the fish body and the smell of freshwater fish is heavy and unacceptable. This study focuses on the odor of American silver carp to provide a foundation for later deodorization to increase utilization of the American silver carp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
