Nanotechnology In Space Food

Key Concepts and Definitions

Nanotechnology refers to the manipulation of matter at the nanoscale—typically between 1 and 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that can be harnessed for various applications. In the context of space food, nanotechnology is used to improve food preservation, enhance nutrient delivery, and create compact, efficient packaging. Key concepts include:

• Nanoparticles: Tiny particles that can be engineered to deliver nutrients or act as antimicrobial agents.
• Nanoencapsulation: A process where nutrients or flavors are enclosed within nanostructures to protect them from degradation.
• Nanocoatings: Thin layers applied to food or packaging to extend shelf life and prevent contamination.
