【摘要】 本研究采用光学和扫描电镜、X射线衍射仪、氮气吸附脱附曲线测试仪，对郎酒三合土晾堂和水泥混凝土晾堂孔结构和矿物组成进行分析。结果表明，三合土晾堂是一种典型的多孔材料，该材料主要以毫微米级孔为主，吸水率18.3%、孔隙率34.8%;Fiji ImageJ软件图像分析表明，三合土试样总孔面积占比为31.3%，毫米、微米、纳米级孔的孔径分布分别为63.3%、34.8%、1.9%；混凝土晾堂试样的吸水率仅为3.22%，孔隙率6.59%，总孔面积占比为4.39%，主要为毫米级孔；两种晾堂试样的矿物组成大致相近，只是含量存在很大差别。三合土晾堂毫微米级孔结构对酿酒微生物有负载和选择性负载作用，使之成为酱香白酒酿造微生物菌种的一个来源；另外其吸水性和透气性为酒醅摊晾和发酵的水、气微循环以及微生物繁衍提供了有利条件，最终影响酱香白酒的风味和质量。更多还原

【Abstract】 The porous structure and mineral composition of the traditional trinity mixture fill cooling field and the concrete cooling field were analyzed using optical and scanning electron microscopy, X-ray diffractometry, and nitrogen adsorption-desorption curve tester. The results showed that the trinity mixture fill cooling field is a typical porous material, which mainly consists of nanometer-sized pores, with a water absorption rate of18.3 % and a porosity of 34.8 %. Image analysis using the Fiji ImageJ software revealed that the total pore area of the trinity mixture fill sample accounted for 31.3 % of the total area, with the millimeter-sized, micrometer-sized, and nanometer-sized pores accounting for 63.3 %, 34.8 %, and1.9 %, respectively. The water absorption rate of the concrete sample was only 3.22 %, the porosity was 6.59 %, and the total pore area accounted for4.39 %, mainly millimeter-sized pores. The mineral composition of the two materials were roughly similar, but there were significant differences in the contents. The porous structure of the trinity mixture fill cooling field has a selective loading effect on the brewing microorganisms, making it a source of microorganisms for the brewing of Jiangxiang Baijiu. In addition, its water absorption and air permeability provide favorable conditions for the microcirculation of water and air during stacking fermentation, as well as the proliferation of microorganisms, which ultimately affect the flavor and quality of Jiangxiang Baijiu.更多还原
