Beer Marinade?

IF YOU are frying a steak and mindful of your health, then marinate it in either beer or red wine. So say food scientists who measured amounts of a family of carcinogens found in fried steaks after steeping them in booze.

Interesting report in the New Scientist! I must admit I do like to marinate my meat, often in wine and olive oil. Maybe I'll try some beer. Steak in Guinness has been seen on pub menus.

Here is the abstract:

The effect of beer or red wine marinades on the reduction of heterocyclic aromatic amines (HAs) formation in pan-fried beef was compared. The cooking experiments were performed under well-controlled temperature and time conditions. The samples were analyzed for HAs contents using solid-phase extraction and high-performance liquid chromatography−diode array detection/fluorescence detection. Unmarinated samples cooked in similar conditions provided reference HAs levels. Marinating with beer or with red wine resulted in decreased levels of HAs. The amount of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine and 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline reduced significantly, respectively, around 88 and 40% after 6 h of marinating with beer or with wine. High variations were observed for reductions of AαC, ranging between 7 and 77%. Only beer marinade significantly reduced the levels of 4,8-DiMeIQx at 1, 2, and 4 h of marinating. Multivariate statistical treatment of results indicated that beer can be more efficient on the reduction of some HAs formation. In addition, results from descriptive sensory analysis of unmarinated and 2 h marinated beef samples, tested for by two trained sensory panels, pointed to beer marinade as the most adequate for maintaining the usual overall appearance and quality of the pan-fried steaks.

I have a nice piece of meat in my fridge completely submerged in a nice stout beer. I will let you know how it comes out. Will post it on my blog.
