本研究的目的是比较芒果酒的化学成分和挥发性成分的酿酒酵母变种发酵。bayanus EC 1118，S.酿酒变种chevalieri CICC 1028和S.酿酒变种酿酒酵母菌株EC 1118和MERIT.ferm表现出相似的生长模式，但菌株CICC 1028生长稍慢。每种芒果酒的乙醇水平达到约8%（v/v），并且糖（葡萄糖、果糖和蔗糖）在发酵结束时几乎耗尽。柠檬酸、琥珀酸和酒石酸的浓度变化可忽略不计，但苹果酸除外（显著降低）。产生不同的挥发性化合物，主要是脂肪酸、醇类和酯类。果汁中存在的大多数挥发物被消耗到痕量。三种酵母挥发性物质的动态变化规律相似，但部分挥发性物质的浓度因酵母而异。菌株MERIT.ferm产生更高量的高级醇、乙酸异戊酯和2-苯乙基酯，而菌株CICC 1028产生更高量的中链脂肪酸以及癸酸乙酯和十二烷酸乙酯。这些结果表明，利用不同的S.酿酒酵母菌株。
The aim of this study was to compare the chemical and volatile composition of mango wines fermented with Saccharomyces cerevisiae var. bayanus EC1118, S. cerevisiae var. chevalieri CICC1028 and S. cerevisiae var. cerevisiae MERIT.ferm. Strains EC1118 and MERIT.ferm showed similar growth patterns but strain CICC1028 grew slightly slowly. The ethanol level reached about 8% (v/v) for each mango wine and sugars (glucose, fructose and sucrose) were almost exhausted at the end of fermentation. There were only negligible changes in the concentrations of citric, succinic and tartaric acids, except for malic acid (decreased significantly). Different volatile compounds were produced, which were mainly fatty acids, alcohols and esters. Most volatiles that were present in the juice were consumed to trace amounts. The kinetic changes of volatiles were similar among the three yeasts but the concentrations of some volatiles varied with yeast. Strain MERIT.ferm produced higher amounts of higher alcohols, isoamyl and 2-phenylethyl acetates, whereas strain CICC1028 produced higher amounts of medium-chain fatty acids and ethyl esters of decanoate and dodecanoate. These results suggest that it may be possible to produce mango wines with differential characteristics using different S. cerevisiae strains.
