“For a gallon of elderberry wine, I take a teaspoon full of arsenic then add half a teaspoon of strychnine and then just a pinch of cyanide,” says one of the adorable maiden aunts in the classic movie Arsenic and Old Lace (link to brilliant youtube clip) starring Cary Grant. You could be forgiven for thinking the recent news stories on trace element arsenic in wine came straight from this 1940s dark comedy but unfortunately it did not; this is an extremely serious food safety testing matter that has resulted in a lawsuit being filed.
I have blogged in recent months on the hot topic of arsenic in rice (link to most recent blog post), citing key opinion leaders research and therefore decided to look into what is currently available for arsenic analysis in wine and beverages.
Last year a new application note was published using the latest ion chromatography innovation, high pressure capillary ion chromatography. This time and eluent saving method demonstrates total arsenic and other ions in fruit juices (link to downloadable pdf) but could similarly be used for wine analysis.
