摘要: 本研究以金沙酱香型白酒为对象,系统考察其液滴蒸发行为及沉积图案特征,分析沉积图案与酒体质量之间的相关性。结果表明,不同质量等级酒样在蒸发过程中均出现颗粒自组装,且颗粒在液滴内部液流作用下发生运动与沉积;自组装程度与液流作用差异,导致液滴蒸发结束后在界面留下的沉积图案呈现出显著差异。高质量等级酒样(I~III级)在三相接触线处可观察到更多的自组装颗粒,低质量等级酒样(IV、V级)颗粒数量较少。蒸发模式观察结果显示,I~III级酒样以恒定接触角/恒定接触半径(constant contact radius,CCR)混合蒸发模式为主,伴随明显的“钉扎-滑移”现象,形成不规则多环沉积图案且环内颗粒分布较为丰富;而IV、V级酒样则主要遵循CCR蒸发模式,形成典型咖啡环结构,但环内颗粒分布较少。图像分析显示,沉积图案的积分光密度与感官评分呈显著正相关。经多种市售成品酒验证,确认了上述显著关联的可靠性。气相色谱-质谱分析表明,这种相关性主要与酒体中长链脂肪酸乙酯密切相关。本研究提供了一种基于沉积图案的酱香型白酒质量可视化快速评估方法,可为酱香型白酒基酒与成品酒的快速质量评价提供新策略。

Abstract: This study systematically investigated the droplet evaporation behavior and deposition pattern characteristics of Jinsha Jiangxiangxing baijiu, and analyzed the correlation between the deposition patterns and sensory quality. The results showed that during evaporation, all baijiu samples of different quality grades exhibited particle self-assembly, with particles moving and depositing under the influence of the internal fluid flow within the droplet. The deposition patterns left at the interface after droplet evaporation significantly varied with the degree of self-assembly and fluid flow effects. High-quality samples (Grades I–III) showed a greater number of self-assembled particles at the three-phase contact line, while low-quality samples (Grade IV and V) had fewer particles. The observation of evaporation modes revealed that Grades I–III primarily exhibited a mixed evaporation mode of constant contact angle (CCA) and constant contact radius (CCR), accompanied by pronounced “pinning-slipping” phenomena, resulting in irregular multi-ring deposition patterns with more abundant particle distribution within the rings. In contrast, Grades IV and V mainly followed the CCR evaporation mode, forming typical coffee-ring structures with sparse particle distribution within the rings. Image analysis indicated a significantly positive correlation between the integrated optical density of deposition patterns and sensory scores, validated using various commercially available baijiu products. Gas chromatography-mass spectrometry (GC-MS) analysis suggested that this correlation was closely associated with the content of long-chain fatty acid ethyl esters in baijiu. This study provides a visualization-based method for evaluating the quality of Jiangxiangxing baijiu through deposition patterns, offering a new strategy for the rapid quality evaluation of Jiangxiangxing base and finished baijiu.
