PRIORITY: US 2004-2004/PV609035 10 Sep 2004. DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 27 Substituted thiophenes I (R = C1-4 alkyl or C1-5 acyl) are used as aromatizers, or flavorings, or flavor enhancers. Thus, garlic flavor may be enhanced by adding 3-(methylthiomethyl)thiophene or thioacetic acid S-thiophen-3-ylmethyl ester. .
