ABSTRACT
The potential utilization value of Camellia seed cake was explored by extracting albumin (CSCA) to develop nanoparticles for lutein delivery. First, thermal property and amphiphilicity of CSCA were evaluated to guide nanoparticle preparation. Next, CSCA nanoparticles modified with chitosan (CS) were prepared through a thermally induced self-assembly method derived by electrostatic attraction and hydrophobic interaction. The optimized nanoparticles were prepared from CSCACS at a mass ratio of 21 with pH of 4.5, and an incubation temperature and time of 80 â and 10 min, respectively. The nanoparticles had the highest effective loading capacity for lutein at 5.89 ± 0.78%, and the corresponding encapsulation efficiency was 43.82 ± 5.69%. The storage stability of lutein was improved by nanoparticle loading, and the bioaccessibility of lutein in simulated intestinal digestion increased from 26.8 ± 4.4% to 57.3 ± 9.6% after encapsulation into nanoparticles. These findings may facilitate the development of new and sustainable proteins from plant waste for delivery system applications.
