摘要: 焦糖香气为慕萨莱思典型特征香气,其重要香气物质为5-甲基糠醛(5-Methylfurfural;5-MF)、呋喃酮(Furanone;DMHF)和3-甲硫基丙醇(3-Methylthiopropanol;3-MTP),由于其阈值及相互作用目前尚不清楚。本论文采用3-AFC确定5-MF、DMHF和3-MTP阈值,并运用S型曲线和σ-τ图分析其二元互作关系,以期为慕萨莱思产品风味控制提供参考:5-MF、DMHF、3-MTP在酒精度12%模拟葡萄酒中阈值分别为190 μg/L、45 μg/L和382 μg/L,在酒精度12%慕萨莱思脱香液(7.4~7.9° Brix)中阈值分别为:97.580 μg/L、798.950 μg/L和196.533 μg/L。经研究发现糖度7.4~7.9° Brix和糖度6.4~7.9 °Brix慕萨莱思脱香液(12%酒精度)发现该两种糖度对3种香气阈值的影响较小,8%、10%、12%、14%酒精度慕萨莱思脱香液(糖度7.4~7.9° Brix)中3种香气的阈值无明显差异。运用S型曲线和σ-τ图分析3种香气在12%酒精度的模拟葡萄酒和12%酒精度的慕萨莱思脱香液(糖度7.4~7.9 °Brix)中3种香气的二元混合溶液均呈加成作用。

Abstract: Caramel aroma is the typical characteristic aroma of Msalais, and 5-Methylfurfural (5-MF), Furanone (DMHF) and 3-Methylthiopropanol (3-MTP). Because their thresholds and interactions are still unclear. In this paper, 3-AFC was used to determine the thresholds of 5-MF, DMHF and 3-MTP, and the S-curve and σ-τ plot wree used to analyze their binary interaction, in order to provide a reference for the flavor control of Msalais products: The threshold values of 5-MF, DMHF and 3-MTP in simulated wine with alcohol content of 12% are 190.000 μg/L, 45.000 μg/L and 382.000 μg/L, respectively, and the threshold values of 12% alcohol content of Msalais deodorant are: 97.580 μg/L, 798.950 μg/L and 196.533 μg/L. After research, it was found that the sugar content of 7.4~7.9°Brix and the sugar content of 6.4~7.9 °Brix deodorant liquid (12% alcohol content) found that the two sugar content had little effect on the three aroma thresholds, There was no significant difference in the thresholds of the 3 aromas in the 8%, 10%, 12%, 14% alcohol content of Msalais deodorant (7.4~7.9 °Brix). The binary mixed solutions of the three aromas in the simulated wine with 12% alcohol content and 12% alcohol content in Msalais deodorant (7.4~7.9 °Brix) fluids showed addition effects through the S-curve and the σ-τ plot.
