Outline
In recent years, microcapsule technology has shown broad application prospects in food science and biomedicine due to its protection and controlled release characteristics of active ingredients. Among a variety of wall materials, whey protein has become a promising candidate due to its natural non-toxicity, biocompatibility and biodegradability. This paper first provided an overview of the putamen structure of whey protein-based microcapsules. Secondly, this paper mainly discussed the modification methods of whey protein wall materials: Building composite wall materials with other biological macromolecules; structural modification by physical or chemical methods, as well as improvement of interface properties by Maillard reaction. This paper analyzed the technical characteristics of spray drying, freeze drying and complex coacervation methods and their effects on the properties of whey protein-based microcapsules. The results showed that the embedding rate and stability of microcapsules could be significantly improved by precisely regulating the process parameters. Finally, in the field of application, whey protein-based microcapsules could not only effectively protect the activity of probiotics and achieve targeted delivery of active substances, but also showed application potential in biomedical fields such as controlled drug delivery systems and wound dressings.
