AI Technical Summary
Existing methods for preparing nanocapsules suffer from poor stability and biocompatibility issues, and the formation conditions are strict, making it difficult to efficiently prepare nanocapsules with good biocompatibility.
Citric acid was used as a natural cross-linking agent to prepare protein-polysaccharide complex aggregates through a composite coagulation method, forming citric acid-crosslinked protein-polysaccharide complex nanocapsules. The nanocapsules were formed by utilizing the electrostatic interaction between proteins and polysaccharides.
The prepared nanocapsules have a particle size of approximately 150-200 nm, an encapsulation efficiency of up to 69%, good heat resistance, slow-release core material, good biocompatibility, and are easy to operate, making them widely applicable in the fields of food and drug delivery.
