摘要
研究红枣果酒苦味物质的来源和成分,结果表明,红枣果皮、果核和果肉3个部位中,果皮是影响红枣果酒苦味的主要因素;以中秋酥脆枣和金丝小枣为原料酿造的果酒苦味显著高于哈密大枣(P<0.05);超过80℃的干制可显著增加红枣果酒的苦味(P<0.05);酵母添加量对红枣果酒苦味没有显著性影响(P>0.05)。采用溶剂萃取法提取红枣果酒苦味成分,经GC/MS鉴定,苯乙醇在红枣酒中的含量高达29.06%,是红枣果酒中主要苦味物质。同时检测到酯类、醛类、酚类、酮类物质等其它苦味物质。
The bitter substance origin and composition in Jujube wine were studied. The results showed that, the jujube peel is the main factors of jujube wine bitter. The bitter of Mid-Autumn crisp jujube and Ziziphus jujube wine which were fermented as raw material was significantly higher than Hami jujube (P〈0.05). More than 80 ℃ of dried jujube wine significantly increases the bitterness (P〈0.05). The amount of yeast added to the bitter of jujube wine no sig- nificant effect (P〉0.05). Solvent extraction from jujube wine, by GC/MS identification analysis showed that, phenethyl alcohol content of wine in the jujube of up to 29.06%, is the main wine jujube bitter substances, and to detect esters, aldehydes, phenols, ketones, and other bitter substances.
