Forbes. Many > afficionados of the malted beverage think that beer goes bad when > mishandled. ""Historically, beer has been stored in brown or green > bottles to protect hop-derived compounds from light in a process we call > photodegradation,"" said Forbes. Hops give the beer its flavor and > protects it by inhibiting bacterial growth. But certain elements of > hops, known as isohumulones, are light-sensitive, and their breakdown > can lead to an offensive flavor and smell. Forbes and his team used > sophisticated analytical chemistry techniques to track the reaction, and > found that one of the end-products is what the team calls a "skunky > thiol." As it turns out, the chemical is related to the funky ones in > skunk glands. The research is reported in the Nov. 5 issue of the > European journal Chemistry. - -- Craig Zeni - REPLY TO -->> clzeni at mindspring dot com http://www.trainweb.org/zeniphotos/zenihome.html http://www.mindspring.com/~clzeni/index.html Gladstone to Disraeli: "I predict, Sir, that you will die either by hanging or of some vile disease."
