Notes:

Eden has developed a terpene-based encapsulation technology which uses yeast cells to deliver a slow release of natural compounds for agricultural and non-agricultural uses.

Terpenes are natural compounds which function as defence mechanisms in many plant groups and are released in response to infection, attack by pests, stress or mechanical injury. Terpenes are already widely used in the food flavouring, cosmetic and pharmaceutical industries.

Historically, terpenes have had limited commercial use in the agrochemical sector due to their volatility, phytotoxicity and poor solubility. Eden's platform encapsulation technology provides a unique, environmentally friendly solution to these problems and enables terpenes to be used as effective, low-risk agrochemicals.

The next-generation encapsulation technology, licensed from University of Massachusetts Medical School ("UMMS") recently, provides significant additional benefits to the original system as it allows release to be controlled by environmental factors rather than relying solely upon the chemistry of the substances used. This means that there is more control over the timing of the release of the active compound being carried allowing for further reduction in chemicals applied whilst ensuring maximum effectiveness.

The UMMS license also significantly expands the potential use of the Eden technology in non-agricultural applications such as health and beauty, cosmetics and animal health.
