摘  要:
【目的】考察无机阳离子Ca2+、Mg2+、K+、Na+和无机阴离子Cl-、SO42-对啤酒口感的影响,并对其作用机理进行初步探讨。【方法】采用核磁共振(NMR)检测方法,对不同离子浓度啤酒样品中质子化学位移进行分析。通过感官品评对啤酒样品整体口感协调性进行评价,然后将品评结果与核磁共振检测结果比对来说明利用质子化学位移考察啤酒口感差异的可能性。【结果】无机离子对啤酒体系中的氢键结构的形成起到促进或破坏的作用。口感较好的样品,其核磁共振图谱中羟基质子化学位移相应较大,反之亦然。【结论】口感品评结果与质子化学位移间具有很好的符合度,从氢键缔合的角度来解释无机离子影响啤酒口感的作用机制具有很大的可行性。

摘  要:
[Objective]The study aimed to observe the effect of inorganic positive ions(Ca2+,Mg2+,K+,Na+)and negative ions(Cl-,SO2-4)on beer taste,and make a preliminary study on its mechanism.[Method]Chemical shifts of different ion concentration liquor were analyzed through nuclear magnetic resonance(NMR)method.Moreover,the whole harmony characteristic of beer samples was evaluated by sensory evaluation,and after that,the comparison of sensory evaluation results and NMR results was carried out to show the feasibility of studying beer taste difference by proton chemical shifts.[Results]Inorganic ions can destroy or strengthen the hydrogen bonding.Moreover,the change of chemical shift was higher for the beer sample with better taste,vice versa.[Conclusion]The proton chemical shift was consistent with sensory evaluation very well.It's very feasible to explain the mechanism of inorganic ions affecting on beer taste through the angle of hydrogen bonding of the beer body.
