Biogenic amines in seafood : a review

Abstract

The biogenic amines are low molecular weight organic bases present normally in the body with biological activity influencing important physiological functions. The physiological functions of these molecules are achieved by very low concentrations in the tissues. However, significantly high amounts of biogenic amines are produced during processing and storage of seafood as a result of microbial contamination andinadequatestorageconditions.Microorganismshavingdecarboxylase enzyme activity convert amino acids to their respective biogenic amines. Biogenic amines in seafood have been implicated as a major causative agent of food borne illness, where intoxication results from the ingestion of foods containing higher amount of biogenic amines. Hence its identification, quantitation and awareness of this food borne toxin areimportantinrelationtofoodsafetyandspoilage.Theaimof thispaperistoreviewthebasicconceptsofseafoodqualityand safety in relation to biogenic amines along with its control measures and future areas for research.
