RT Journal Article SR Electronic T1 The Mechanism of Isoamyl Alcohol Formation Using Tracer Techniques JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 161 OP 167 DO 10.5344/ajev.1958.9.4.161 VO 9 IS 4 A1 George Thoukis YR 1958 UL http://www.ajevonline.org/content/9/4/161.abstract AB The mechanism of the formation of isoamyl alcohol during alcoholic fermentation was studied by using radioactive leucine and isovaleraldehyde and determining the percentage of isoamyl alcohol derived from these precursors. The results partially confirm previous work in this field, but also indicate that the ultimate precursor of isoamyl alcohol is to be found in the fermentable sugar.The technique used is a general one, and may be adapted to a variety of fermentation problems.
