A high-resolution colorimetric immunoassay for tyramine detection based on enzyme-enabled growth of gold nanostar coupled with smartphone readout.

Food Chemistry, 2022
In this work, a specific monoclonal antibody against tyramine was produced based on a new hapten design. Then, we developed a high-resolution multicolor colorimetric immunoassay for tyramine based on this antibody by integrating enzyme-induced multicolor

Highly Sensitive Electrochemical Detection of Tyramine Using a Poly(Toluidine Blue)-Modified Carbon Screen-Printed Electrode

IEEE Sensors Journal, 2022
Tyramine (4-hydroxyphenethylamine) is a biogenic amine commonly found in alcoholic beverages or fermented and dried foods. A healthy person can consume about 200–800 mg per single oral intake.

Mutagenic products are promoted in the nitrosation of tyramine [PDF]

Food Chemistry, 2017
Tyramine is a biogenic compound derived from the decarboxylation of the amino acid tyrosine, and is therefore present at important concentrations in a broad range of raw and fermented foods.

Multiplexed fluorescence immunoassay combined with magnetic separation using upconversion nanoparticles as multicolor labels for the simultaneous detection of tyramine and histamine in food samples.

Analytica Chimica Acta, 2020
We have developed an upconversion nanoparticles (UCNPs) based fluorescence immunoassay for simultaneously detecting tyramine and histamine in foods. The anti-tyramine and anti-histamine antibody were linked to NaYF4Yb, Tm (emission at 483 nm) and NaYF4Yb,

Solid-state potentiometric sensor for the rapid assay of the biologically active biogenic amine (tyramine) as a marker of food spoilage.

Food Chemistry, 2020
Tyramine (TYR) is a vasoactive biogenic amine found in food products due to improper storage and poor hygiene. High TYR intake results in a wide range of life-threatening physiological reactions.
