摘要
以叶黄素酯晶体为芯材,用喷雾-淀粉流化造粒技术制备5%叶黄素酯微囊粒的配方和工艺。方法:通过单因素和正交试验对配方和工艺进行了优化。结果表明:最佳配方为叶黄素酯晶体(含量80%)质量分数6.30%、红花籽油质量分数15.00%、改性淀粉HI-CAP100质量分数24.76%、乳糖质量分数31.71%、抗坏血酸钠质量分数1.00%、吐温-80质量分数0.03%、混合生育酚质量分数1.20%和淀粉质量分数20.00%;喷雾造粒工艺参数为:物料黏度120 mPa·s、物料流速0.40 mL/s、喷头转速2500 r/min和进风温度120℃。微囊化使叶黄素酯的水溶性、稳定性得到了明显的改善,为叶黄素酯提供了更广阔的应用领域。
The formula and process of preparing 5% lutein ester beadlet by spraying and starch catching granulation technology using lutein ester crystal as the core material were studied. Methods： The formulation and process were optimized by single factor and orthogonal test. Results： The optimal formulas were lutein ester crystal mass fraction 6.30%, safflower oil mass fraction 15.00%, modified starch HI-CAP100 mass fraction 24.76%, lactose mass fraction 31.71%, sodium ascorbate mass fraction 1.00%, Tween-80 mass fraction 0.03%, mixed tocopherol mass fraction 1.20% and starch mass fraction 20.00%. Material viscosity 120 mPa·s, material flow rate 0.40 mL/s, sprayer speed 2500 r/min and inlet air temperature 120 ℃ were found optimal for parameters of spraying and starch catching granulation technology. Microencapsulation significantly improved the water-solubility, stability of lutein ester, providing a broader range of application for lutein ester.
