Savvy cooks often use beer in cooking, and the right brew served on
the side can compliment many a fine dish. But now, researchers report
that marinating meat in beer prior to grilling could reduce the formation of substances suspected to be harmful.
Grilling meats at high temperatures creates substances known as
polycyclic aromatic hydrocarbons (PAHs) which in some studies have been
associated with increased risk for colorectal cancer.
Researchers from Portugal and Spain conducted experiments using beer
as a marinade and measuring PAHs after grilling. Results of their tests
are published in the Journal of Agricultural and Food Chemistry.
The researchers marinated pork for four hours in Pilsner beer,
non-alcoholic Pilsner beer or black beer, and then grilled the samples
to well-done on a charcoal grill.
According to the research report, black beer showed the highest
inhibitory effect, reducing the formation of PAH by 53 percent, followed
by non-alcoholic Pilsner beer at 25 percent reduction (finally, a use
for non-alcoholic beer). Regular Pilsner beer provided a reduction of 13
percent. The researchers concluded that using beer marinades,
particular dark beer, could provide a suitable mitigation strategy for
PAHs in grilled meats.
