NMR spectroscopy has become an important technique to
study biological tissues. Since tissues are in
semisolid-state, high-resolution (HR) spectra of tissues
cannot be obtained by conventional NMR spectroscopy. In
this study, the feasibility of HR
ex
vivo
spectroscopy
based on ultrafast intermolecular single-quantum
coherence (UF iSQC) technique is explored using fish
muscle and eggs. Furthermore, the metabolites variations
of fresh and decayed tissues are explored. The
experimental results indicate that UF iSQC technique is
a fast feasible way for HR NMR spectrum of fish tissues
and suitable for quality control of semisolid food and
inspections on biological tissues
in
vivo
