Abstract: SUMMARY This paper describes the separation and partial identification of 10 volatile fatty acids present in apple wine. The acidic fraction was prepared by “stripping” the wine in a rising film evaporator and separating the volatile acids from the strippings by appropriate pH adjustment, steam distillation and extraction. When the volatile acids of apple wine were examined by gas chromatography, using Ucon 50‐HB‐2000 and Uconnonpolar, ten distinct peaks were revealed. In addition the volatile acids were methy… Show more

“…Although it was quite easy to dis- tinguish between the n-and iso-forms of the acids, it was not possible to distinguish between the various iso-forms of the same acid. As expected, a straight line was obtained between the log of retention time and carbon number for n-fatty acids, which is in good agreement with results of Sugisawa et al (1962). Previous workers, using column chromatographic separation of the volatile fatty acids present in sawdust smoke, identified formic, acetic, propionic, and butyric acids (Husaini and Cooper, 1957).…”
