In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Identification and Sensory Characterization of Volatile Flavor Compounds in Sesame Seed Oil, published in 1996-12-31, which mentions a compound: 616-43-3, mainly applied to volatile flavor compound sesame seed oil, Reference of 3-Methyl-1H-pyrrole.
Volatile flavor compounds in sesame seed oil were investigated. Com. processed sesame seed oil was steam distilled under reduced pressure, and volatiles from the distillate were separated by an adsorptive column method. Among 171 individual peaks detected, 134 peaks were definitely or tentatively identified by anal. of mass spectra and modified Kovats indexes. To elucidate the compounds directly contributing to the characteristic flavor, the odor concentrate was fractionated by silica gel thin-layer chromatog. and preparative gas chromatog. As a result, 1-(5-methyl-2-furanyl)-1-propanone, 3-formylthiophene, 2-propyl-4-methylthiazole, 2-ethyl-4-methyl-1H-pyrrole, 2-ethyl-6-methylpyrazine, 2-ethyl-5-methylpyrazine, 4,5-dimethylisothiazole, 4,5-dimethylthiazole, 2,6-diethylpyrazine, 2-ethyl-2,5-dimethylpyrazine, 1-(2-pyridinyl)ethanone, and 1-(1-methyl-1H-pyrrol-2-yl)ethanone were considered to be principal contributors of sesame seed oil flavor.
Compounds in my other articles are similar to this one(3-Methyl-1H-pyrrole)Reference of 3-Methyl-1H-pyrrole, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
