A fast, inexpensive test that can help avoid ‘out of the blue’ headaches followed by consumption of certain red wines, cheese, chocolate, and other aged or fermented foods has been developed. The study led by Richard A. Mathies, a chemist with UCLA, Berkeley, reported the development of a home use test, which could prove beneficial for millions of people.
The test is designed to detect the presence of biogenic amines or naturally occurring toxins that can trigger a wide range of symptoms in sensitive individuals, starting from nasty headaches to life-threatening episodes of high-blood pressure. Biogenic amines include tyramine, histamine, and phenylethylamine, which are known to cause nausea, headaches, and respiratory disorders. The researchers state that the new test can produce results within five minutes.
“These toxins can be serious health problem and are more common than people think. They are hidden in a wide variety of foods. Having a quick, convenient way to identify them will help consumers avoid them or at least limit their intake”, Mathies said.
In the study, the researchers used a prototype device to analyze tyramine and histamine concentrations in a variety of wines (both red and white), beer and sake. After reviewing, they found that the device accurately measured the biogenic amines present in the beverages in less than five minutes. The researchers noted that red wine had the highest levels of tyramine and the highest levels of histidine were found in sake. However, the beer tested contained small amounts of biogenic amines.
“Some foods have more biogenic amines than others, but you can’t tell because they aren’t listed on the food labels. I think that certain foods, especially wines, should indicate their biogenic amine content,” Mathies said.
The study appeared in the journal of ACS’ Analytical Chemistry.
