Plastic wrap: what's that musty smell?

Plastic wrap: What's that musty smell?

Plastic wrap for food is meant to be barely seen and certainly not smelled. But recently Kraft Inc. found that a shipment of plastic film provided by their supplier had a "musty' odor that would have tainted their food products. With a series of chromatographic, spectroscopic and synthetic techniques-- coupled with the use of their noses--chemists at Kraft's Basic Flavor group in Glenview, Ill., found the culprit: 4, 4, 6-trimethyl-1, 3-dioxane, formed by the reaction between formaldehyde and a solvent coating used to help ink adhere to the film. "This analytical approach illustrates how an arsenal of sophisticated methods may be used to solve a real-world analytical problem,' write Robert J. McGorrin, Thomas R. Pofahl and William R. Croasmun in the Sept. 15 ANALYTICAL CHEMISTRY.
