摘要: 探讨牡蛎肽-锌纳米粒的形成条件及稳定作用力。通过透光率检测初步筛选牡蛎肽-锌纳米粒形成的条件,用粒径分析和电镜观察方法确认纳米粒的形成。通过次级键破坏实验分析稳定纳米颗粒空间结构的作用力。结果表明,在牡蛎肽中加入0.5%0.9%的硫酸锌后,将体系p H调至6.011.0,即可制得粒径为28102 nm的牡蛎肽-锌纳米粒。锌是纳米粒的必需组分,疏水作用和静电相互作用是稳定纳米粒的关键作用力。牡蛎肽-锌纳米粒有望成为新型补锌制剂。Abstract: To investigate the formation and stabilized force of oyster peptide-zinc nanoparticles, the formation conditions could be preliminary screened by turbidity test and the formation of nanoparticles could be confirmed by particle size analysis and electron microscope observation.The stabilized force could be determined through secondary bond destruction experiments. The results showed that nanoparticles whose diameters ranging from 28 ~ 102 nm were formed when 0.5% ~ 0.9% zinc sulfate was added in oyster peptide solvent with p H6.0 ~ 11.0. Zinc was an essential component of nanoparticles, hydrophobic force and electrostatic interaction were the key forces for stabling the nanoparticles. Oyster peptide-zinc nanoparticles were expected to become the new zinc supplements.
