By utilizing a combination of biocompatible polymers and silica nanoparticles, the technology creates a protective matrix around ice crystals, effectively minimizing risks associated with melting and sublimation during storage and transit.
[021] The composition of the nanomaterials is engineered to ensure biocompatibility, making them suitable for applications in both food preservation and pharmaceuticals. This is crucial as it ensures that the materials do not compromise the safety or efficacy of the products they aim to protect, addressing industry standards for health and safety.
[022] The encapsulation of ice crystals is achieved through a multi-step process that begins with the dispersion of nanomaterials in a water solution. This step ensures that the nanomaterials are evenly distributed, providing consistent coverage and enhancing the interaction with the ice crystals, which is critical for effective stabilization.
