Fresh Produce Protection

TarriTech develops delivery systems
for effective protection of fresh produce

The Need

Along the food chain, more than $1 trillion worth of food is lost! About $400bn worth of harvested agricultural produce is lost in the food supply chain – from the farmer to the consumer – mainly due to decay

It is estimated that up to $250bn can be recovered by improving efficiency and infrastructure. This loss of value, and the need to feed the ever-increasing world population with better-quality fresh produce at affordable prices, create huge business opportunities

Strawberries and other berry markets are growing due to the demand for both fresh and processed produce. TarriTech™ plans initially to address the strawberry market, which is worth globally more than $15bn.  The US spends more than $3bn on strawberries and $3.5bn on other berries. Berries are extremely perishable fruits, and their consumption is limited in terms of shelf-life and distance from producer to consumer. By reducing post-harvest decay, the availability of undamaged fruit and the flexibility of the supply chain increase significantly. Many business opportunities are opened to all players – farmers, shippers and retailers.


Our Solution

TarriTech has developed a unique delivery system, which effectively and repeatedly operates to prevent the decay of fresh vegetables, fruit and herbs. Fresh produce, prior to its storage or transport, is exposed for a short period to a controlled profile of volatile compounds, released by our delivery system from a mixture of several essential oils. The selected essential oils, each with a specific biological activity, when combined, prevent the decay caused by several types of microorganisms. The system is tailored to specific crops and designed to integrate into existing packing house processes.

The oils used by TarriTech are registered as GRAS  (generally recognized as safe). They do not affect the taste, aroma or appearance of the fresh produce. Incorporation into an existing line of post-harvest treatments requires minimal investment, at a low operational cost. Our process has already been commercialized with tangerines and carried out on a pilot scale with strawberries, peaches, nectarines and persimmons.

Extensive research into the chemical composition of essential oils and their biological effect as a decay control agent, has resulted in a comprehensive database. Using the database TarriTech correlates the chemical composition of selected essential oils,  and the profile of the volatile compounds released into the gas phase, to the biological effect on the decay of a specific fresh crop. Cooperation with the post-harvest industry led to the development of TarriTech‘s unique delivery system.

TarriTech’s delivery system is generic and tailored to treat any fresh produce by adapting it to the existing production-line of the packing house.


  • No undesirable effects on original taste, appearance and aroma.
  • No chemical residue..
  • No phytotoxic effects.
  • Low investment and operating costs.
  • Simple integration into operating post-harvest treatment lines.
  • Essential oils used are registered as safe edible products in the GRAS (Generally Regarded As Safe) index
  • The regulatory procedure is expected to be short.
