Physiological importance[ edit ] There is a distinction between endogenous and exogenous biogenic amines. Endogenous amines are produced in many different tissues for example: adrenaline in adrenal medulla or histamine in mast cells and liver. The amines are transmitted locally or via the blood system. The exogenous amines are directly absorbed from food in the intestine. Alcohol can increase the absorption rate.

Monoamine oxidase MAO breaks down biogenic amines and prevents excessive resorption. Importance in food[ edit ] Biogenic amines can be found in all foods containing proteins or free amino acids and are found in a wide range of food products including fish products, meat products, dairy products, wine, beer, vegetables, fruits, nuts and chocolate.

In non-fermented foods the presence of biogenic amines is mostly undesired and can be used as indication for microbial spoilage. In fermented foods , one can expect the presence of many kinds of microorganisms , some of them being capable of producing biogenic amines.

They play an important role as source of nitrogen and precursor for the synthesis of hormones , alkaloids , nucleic acids , proteins , amines and food aroma components. However, food containing high amounts of biogenic amines may have toxicological effects.

When present in wines in high amount, biogenic amines may cause not only organoleptic defects but also adverse effects in sensitive human individuals, namely due to the toxicity of histamine, tyramine and putrescine. Even though there are no legal limits for the concentration of biogenic amines in wines, some European countries only recommend maximum limits for histamine. In this sense, biogenic amines in wines have been widely studied. The determination of amines in wines is commonly achieved by liquid chromatography, using derivatization reagents in order to promote its separation and detection.

In alternative, other promising methodologies have been developed using capillary electrophoresis or biosensors, revealing lower costs and faster results, without needing a derivatization step. It is still a challenge to develop faster and inexpensive techniques or methodologies to apply in the wine industry.
