通过扫描电子显微镜( SEM) 、聚焦光束反射测量仪( FBRM) 监测碳酸法饱充体系中碳酸钙颗粒形态、生成速度和粒径的变化，同时以色值、还原糖含量和简纯度为指标，监测CO₂饱充流速对碳酸钙颗粒的影响，研究影响碳酸钙颗粒吸附非糖分的因素．实验结果表明: 在较低的CO₂饱充流速下，碳酸钙颗粒为表面结构紧密的立方体，而在较高的CO₂饱充流速下，碳酸钙颗粒为表面呈层状的棒形结构; FBRM 在线观测发现体系固体颗粒弦长主要在1 ～100μm 范围内，并且随着CO₂饱充流速的增大，体系颗粒粒径向大尺寸范围变化;快速饱充能保护还原糖不受破坏;通入等量CO₂时，随CO₂饱充流速的增大，清净汁色值降低，简纯度升高; CO₂饱充流速对无机阳离子K⁺、Na⁺、Ca²⁺、Mg²⁺的吸附影响不大; 因此在适宜的CO₂饱充流速( 300 ～900mL/min) 范围内，快速饱充是一项切实可行的澄清技术．

In order to study the factors that influence the adsorption of non-sugar by calcium carbonate during the process of carbonation in multi-component syrup and to clarify the effects of CO₂ flow rates on CaCO₃ particles,the morphologies,formation rate and sizes of the CaCO₃ particles were characterized by means of SEM and FBRM. Moreover,the color value,the content of reducing sugar and the apparent purity were determined as the indexes. Experimental results show that ( 1) the CaCO₃ particles are cube-shaped at a lower CO₂ flow rate while they are rod-like at a higher flow rate; ( 2) the CaCO₃ particle chord lengths obtained by using an on-line FBRM are within a range of 1 ～ 100 μm,and the range becomes wider with the increase of the CO₂ flow rate; ( 3) fast carbonation can protect the reducing sugar from destruction; ( 4) when the CO₂ content is constant,with the increase of the CO₂ flow rate,the color value of clarified juice decreases while the corresponding apparent purity improves; ( 5) the CO₂ flow rate has little influence on the adsorption of the inorganic cations of K ⁺ ,Na ⁺ ,Ca^{2 +} and Mg^{2 +} ; and ( 6) within an appropriate flow rate range of 300~900mL /min,fast carbonation proves to be a feasible clarification technology.
