通过乳化-冷冻干燥联合技术构建微胶囊体系,以实现对具有不同极性的物质(亲水性硒肽和亲脂性VE)的稳态化共封装.以包埋率作为参考,通过单因素试验考察壁材浓度、硒肽和VE含量等工艺参数对包埋效果的影响.傅里叶变换红外光谱和扫描电子显微镜图像表明微胶囊能够有效封装硒肽和VE,并且具有较好的水分散性,复溶后仍保持双重乳液结构.热稳定性分析和2,2'-联氮双(3-乙基苯并噻哇啉-6-磺酸)阳离子自由基清除实验结果证实,相比于硒肽粉末,微胶囊具有更高的热稳定性和抗氧化活性.电子鼻分析结果进一步证实微胶囊体系对硒肽自身异味具有较好的遮掩效果.体外模拟消化实验表明,微胶囊封装提高了硒肽在模拟胃...

A microcapsule system for the co-encapsulation of selenium-enriched peptides,being hydrophilic,and vitamin E(VE),being lipophilic,was developed using a combination of emulsification and freeze-drying.The effects of wall material concentration,selenium-enriched peptide content,and VE content on the encapsulation efficiency was investigated by single-factor experiments.Fourier transform infrared(FTIR)spectroscopy and scanning electron microscopy(SEM)showed that the selenium-enriched peptides and VE were effectively encapsulated in the microcapsules,and the microcapsules possessed good water disp...
