摘  要:
研究酒类主要风味物质对乙醇-水体系中的氢键缔合影响。Plackett-Burman试验可知,异丁醇、β-苯乙醇、乙酸乙酯、KCl、NaCl、MgSO4、苹果酸、乳酸、丙酮酸对乙醇-水体系中氢键缔合影响最大。根据相关性分析,酒精度与啤酒中氢键缔合强度的相关系数为0.629,是主要影响因素;原麦汁浓度、异丁醇、氯离子、钾离子、丙酮酸、乳酸与氢键缔合均有一定的正相关性。

摘  要:
The effect of major flavor compounds in wine on hydrogen bonds of water-ethanol system was studied.PlackettBurman experiments confirmed that hydrogen bonds of water-ethanol system were greatly affected by isobutanol,β-phenylethyl alcohol,ethyl acetate,KCl,NaCl,MgSO4,malic acid,lactic acid and pyruvic acid.Correlation analysis indicated that coefficient between alcohol concentration and hydrogen bond intensity was 0.629.Therefore,alcohol concentration was the primary factor to hydrogen bond intensity although original wort concentration,isobutanol,Cl-,K+,pyruvic acid and lactic acid also exhibited an influence on hydrogen bond intensity to some extent.
