Abstract In this chapter, we report on the diverse applications of silica-based nanomaterials relevant for the food industry. The encapsulation of food ingredients and nutraceuticals and their use as antimicrobial agents and sensors has been explored. In the case of food ingredients, controlled-release materials responsive to pH changes and enzymes (i.e., proteases or esterases) are the main approximation. For antimicrobial agents, the materials are able to modulate the activity of the biocide, increasing the duration of the active substances. Also, an increase of the biocide activity up to ninefold and a broadening of the activity spectra have been observed for a capped material. Finally, due to their present relevance in the sensors area, we review examples of nanogated silica materials and optoelectronic noses.
