NaturePack EO
Development project · not yet a commercial product
NaturePack EO explores an active-packaging sachet for fresh fruit and vegetables, using plant essential oils encapsulated in β-cyclodextrin and released slowly in the vapour phase inside the packaging. The aim is to reduce spoilage and post-harvest losses with a natural alternative to synthetic preservatives.
The planned research will assess release behaviour, antimicrobial performance, packaging compatibility, safety and regulatory requirements for selected produce. In June 2026 STI submitted, as sole applicant, a proposal to an EU-funded open call for validation in real-life test environments; it was under evaluation in October 2026.

Possible applications
- Pears, apples, kiwi fruit, berries
- Tomatoes, peppers, onions, carrots
- Leafy vegetables and fresh herbs
- Storage, transport and retail packaging
About this presentation. NaturePack EO is a development project within STI and is not yet a commercial product. The presentation brings together research and validation evidence, the planned product, and the route to pilots and market entry. Safety and performance statements refer to the ingredients, formulations, produce and test conditions described; product-specific safety and regulatory assessment remains part of the development programme. STI was established in Bratislava in 2006; its registered office is now in Košice.
What this means for you
STI works across research and industry, structures IP and develops technology with its own people. That is the capacity we bring to the companies and assets we invest in – including those in difficulty.
