Researchers developed a printable strategy to create arrays of encapsulated spices for controlled odor release. This technology enables selective fragrance release and mixing, with applications in food security and anticounterfeiting.
Area of Science:
- Materials Science
- Chemical Engineering
- Sensory Science
Background:
- Olfactory perception is crucial but susceptible to interference.
- Developing controlled odor-release strategies is essential for enhanced communication and applications.
Purpose of the Study:
- To report a fully printable strategy for integrating odor-containing materials and protective coatings.
- To create encapsulated arrays capable of quantitative and selective odor release.
Main Methods:
- Heterogeneous integration of odor-containing materials and protective poly(lactic-co-glycolic) acid (PLGA) shells via printing.
- Fabrication of encapsulated arrays on flexible or rigid substrates with over 20 spices.
- Selective release of odor molecules achieved by scraping protective shells.
Main Results:
- Successfully printed encapsulated arrays with diverse spices.
- Demonstrated quantitative release of odor molecules upon removal of protective PLGA shells.
- Enabled selective release and arbitrary mixing of multiple spices from arrays on a single substrate.
Conclusions:
- The developed encapsulated arrays offer effective odor-releasing properties.
- This technology shows promise for applications in food security, anticounterfeiting, olfactory discrimination studies, and olfactory communication enhancement.
