Direct sampling gas chromatography used for determining volatiles and, indirectly, the flavor of vegetable oils, has been improved by a capillary column in place of the usual packed columns. Data on two good vegetable oils from a supermarket, and on

A simple, rapid, unconventional gas chromatographic procedure is described for objectively assessing the flavor (odor) quality of commercial egg products. The method requires no prior distillations or other means for the enrichment of volatiles. Samp

Profiles of volatiles of whole rice, brown rice, polished rice, rice bran, rice breakfast cereal, whole corn, and corn breakfast cereal were obtained by direct gas chromatography without prior enrichment of volatiles. Some of the volatiles were ident
