 note = {application/pdf, ブドウおよびリンゴ果汁を原料とする果実酢のモデル発酵試験を行い，各発酵段階における脂肪酸成分を分析した.(1) ベリ-A種のワインでは，果汁と比べ，相対的にC16:O酸とC18:O酸の割合の増加ならびにC18:2酸とC18:3酸の減少が認められた.このワインを原料とするブドウ酢の脂肪酸成分の変化は大きくなかったが，C18:1酸の増加が特徴的であった.(2) 甲州種のワインの脂肪般組成は，果汁のそれと類似したが，ベリ-A種とはやや異なった.しかし，このブドウ酢は，ベリ-A種のブドウ酢と質的および量的に類似した脂肪酸成分となった.(3) リンゴ酒では果汁と比べ，相対的なC18:1酸の増加とC18:2酸の減少が観察された.このリンゴ酒を原料とするリンゴ酢の脂肪酸成分の変化は，ブドウ酢と同様にC16:O酸とCI18:O酸の増加であった.(4) このように原料果汁は，それぞれ固有の脂肪酸組成を有していたが，果実酌になるといずれも類似した脂肪酸成分となった.(5) キャピラリGC分析の結果，酢酸発酵で酢酸菌体由来のC18:1 11酸が，果実酢中に移行することが示された.(6) C18:1 11酸は市販10種の果実酢中にも検出され，C18:1 11酸/(C18:1 9酸+C18:1 11酸)比を算出すると0.07-0.59であった., Wine and cider vinegars were experimentally manufactured from commercial grape and apple juices， and differences in fatty acid components were analyzed among fermentation stages. Following alcoholic fermentation of Bailey A (a grape variety for red wine) juice，the increase in the proportions of palmitic and stearic acids was found to be accompanied by relative decreases in those of linoleic and linolenic acids. Reversed phase HPLC analysis showed a notable increase in a peak corresponding to oleic acid during acetic acid fermentation，although changes in fatty acid components were slight compared with those during alcoholic fermentation. In the case of Koshu (a grape variety for white wine)，no significant difference was observed in fatty acid composition between the juice and its fermenting liquid (wine).H owever，after acetic acid fermentation， the vinegar produced had a fatty acid composition that was qualitatively and quantitatively similar to that of Bailey A. During alcoholic fermentation of apple (Delicious variety) juice，an increase in oleic acid and a decrease in linoleic acid were observed，followed by increases in palmitic and stearic acids after acetic acid fermentation，similar to changes observed during wine vinegar manufacturing. Thus，we found that juices with characteristic fatty acids produce vinegars with roughly corresponding compositions. Moreover，capillary-GC analysis of fatty acid methyl esters showed that cis-vaccenic acid (an oleic acid isomer) originating from acetic acid bacteria can be transferred into vinegars made by the acetic acid fermentation process. cis-Vaccenic acid was also detected in ten varieties of commercial wine and cider vinegars with cis-vaccenic acid/(oleic and cis-vaccenic acids) ratios of 0.07-0.59.},
