Comparison of the delivery characteristics of three lutein lipid-based delivery systems stabilized by zein peptide: nanoemulsion, solid lipid nanoparticles and nanostructured lipid carrier

Zein (Zein) is a small molecule physiologically active peptide obtained by enzymatic hydrolysis.

01.

By comparing the surface hydrophobicity, FTIR spectrum and interface characteristics of Zein, FZP and TZP, it is found that the surface of TZP is more hydrophobic, there are more hydrogen bonds in the structure, and it has a larger contact angle

The NE, SLN, and NLC loaded with lutein were stored for ten days at room temperature, and the changes in particle size, potential, and color difference were monitored during this period

Compare the digestion characteristics of different NE, SLN and NLC samples through simulated digestion experiments

Two different zein peptides were obtained by hydrolyzing zein by trypsin and flavor enzymes, and they were further used as interface stabilizers, respectively, and successfully constructed three lipid-based delivery carriers loaded with lutein, including NE, SLN and NLC
