Organic Taste-Active Components in the Hot-Water Extract of Yellowtail Muscle

抄録

Hot-water extracts from the muscle of yellowtail Seriola quinqueradiata were analyzed for low-molecular-weight substances and organic taste-active components were identified by sensory tests (omission and addition tests). Free amino acids, adenine nucleotides, creatine, lactic acid, and inorganic ions (Na⁺, K⁺, Cl⁻, and PO₄^3–) were abundant in the muscle extract. In the reconstituted extract prepared on the basis of the analytical data, the following substances were identified as the organic taste-active components by the sensory test: free amino acids (glutamic acid, α-aminobutylic acid, α-aminoadipic acid, β-aminoisobutyric acid, γ-aminobutyric acid, and histidine) and a nucleotide IMP.
