Sixty-three compounds were isolated and identified from heated starch and from heated starch with glycine. Starch or starch with glycine was heated in an Erlenmeyer flask at 290°C under a nitrogen stream. The volatiles formed during heating were entrained on a porous polymer (Porapack Q). Residual charred materials in the flasks were extracted with methylene chloride. The oily dark brown materials recovered from both the Porapack Q traps and the methylene chloride extracts were subjected to gas chromatography and gas chromatography/mass spectrometry. The compounds identified include 3 hydrocarbons, 1 1 ketones, 3 aldehydes, 24 aromatic compounds, 10 furans and 12 nitrogen-containing compounds.Formation mechanismsof somemajor products are proposed.
