ABSTRACT
A natural antioxidant
was extracted with ethanol from shrimp (Pandalus jordani)
waste samples. Purification of the antioxidant was accomplished
with thin layer and high performance liquid chromatography.
Purified samples were analyzed with a combination of techniques
including Fourier transformed-infrared spectrometry, mass
spectrometry (EI and CI), and proton nuclear magnetic
resonance. The antioxidant is a polar monohydroxyl phenolic
compound with ortho-position substitution and a molecular
weight of 164. Crude and purified extracts were
tested for preventing lipid oxidation of in fatty fish
mince and retaining color in red-skinned rockfish. Both
tests demonstrated practical applications for the antioxidant
for inhibiting oxidation reactions in susceptible seafood
products.
