| 摘 要： | 以罗非鱼鱼鳞为原料，采用超声辅助复合有机酸制备柠檬酸-苹果酸钙（calcium citrate malate，CCM），研究鱼鳞预处理方法、超声辅助酸制备工艺条件，并对产物进行表征。结果显示，鱼鳞无需熬煮，直接采用超声辅助提取效果理想；在液料比为20∶1（mL/g）条件下，正交试验优化得到复合钙最佳制备工艺条件为：柠檬酸和苹果酸总质量分数12%、二者质量比2∶1、超声温度70 ℃、超声时间1.0 h；在此条件下，得钙率为18.97%；红外光谱及X射线衍射分析均显示制备产物不是柠檬酸钙与苹果酸钙的简单混合物，而与CCM结构吻合；扫描电镜观察到产物结晶呈六方形；晶体比表面积介孔测定知罗非鱼鱼鳞复合钙产物孔径为4.049 nm，单点吸附总孔体积为0.320 cm3/g，T-图法微孔（外）比表面积为385.703 m2/g。本方法成功制备了罗非鱼鱼鳞CCM复合盐，得钙率较高，研究结果可为罗非鱼鱼鳞加工有机钙产品提供一定理论支持。

| Abstract: | In this paper, calcium citrate malate (CCM) was prepared by ultrasonic-assisted organic acid treatment of tilapia scale. The pretreatment and preparation conditions were optimized and the structure of the product were characterized. The results showed that good extraction efficiency was obtained by ultrasonic-assisted preparation of fish scale without boiling. At a solvent-to-solid ratio of 20:1 (mL/g), the optimum conditions for preparing CCM were obtained by orthogonal array design as follows: 12% (m/m) of an citric acid-malic acid mixture at a mass ratio of 2:1, temperature 70 ℃ and time 1.0 h. Under these conditions, the maximum extraction rate of calcium of 18.97% was obtained. Infrared spectroscopy analysis and X-ray diffraction (XRD) showed that the product was not a physical mixture of calcium citrate and calcium malate, but coincided with the structure of CCM. Scanning electron microscope showed that the crystal structure was a hexahedron. The specific surface area from mesoporous pore volume determination of the product was 385.703 m2/g, average pore size 4.049 nm and single point adsorption total pore volume 0.320 cm3/g. CCM was successfully prepared by this method with higher yield of calcium. These research results provide some theoretical support for the processing of organic calcium products from tilapia scale. |
