Vapors from rancidifying bulgur and from autoxidized methyl linoleate, a model compound, are being analyzed and identified by gas liquid chromatography and mass spectrometry. Thirty-one compounds have now been tentatively identified in studies on the model system. The presence of some of these compounds in vapors from rancid bulgur has been verified. We have made further study of gun-puffing and hot-air puff-drying as alternate means of preparing wheat ingredients for the wafer. Development of a jelly that sets with cold water essentially concludes development work on adjuncts. Long-term five-year storage studies of bulgur wafers and adjuncts are continuing. Taste panel evaluations to date indicate that shelf life of both types of products can be extended with nitrogen-packaging. The use of malt instead of corn syrup in wafer formulation and of in-package desiccants with adjuncts also extends shelf life. Chemical-physical measurements of changes taking place are being made on duplicates of the samples evaluated by the taste panel to find a test that will correlate with organoleptic evaluations, but as yet no meaningful correlations have been found.
