Safeguard your precious fruit

Optiflux principle

Recently, the Food Agricultural Organization of the United Nations (FAO) predicted that the world population would top eight billion by the year 2030. Therefore, the demand for food would increase dramatically. According to the report, crop output is projected to be 70 percent higher in 2030 than current output. Fruits and vegetables will play an important role in providing essential vitamins, minerals, and dietary fibre to the world, feeding populations in both developed and developing countries. However, during postharvest storage, transport and distribution, losses up to 50% occur. Currently, ‘controlled atmosphere systems’ (CA systems) are the state-of-the-art agricultural storage methods in which the concentrations of oxygen, carbon dioxide and nitrogen, as well as the temperature and humidity of a storage room are empirically determined and often suboptimal resulting in more losses than expected.

Optiflux has developed and patented an innovative and non-chemical system to optimize the controlled atmosphere gas composition to the needs of the product being stored or transported, by measuring fruit respiration. With Optiflux dynamic controlled atmosphere (DCA) storage, the oxygen level in the storage facility is gradually decreased until, based on measurement of respiration of the fruit, low oxygen stress is detected. Subsequently, the oxygen level is slightly increased until relief of low oxygen stress. In this way, the fruit is stored at the lowest oxygen level possible resulting in maximal quality preservation without development of disorders and off-flavors.

Evidence from research

To evaluate the effect of OptifluxTM technology on post-storage quality of apple fruit, a pilot infrastructure was built in collaboration with the Postharvest Group of KU Leuven and the Flanders Centre of Postharvest Technology (VCBT). Long term storage experiments complemented with extensive shelf life exposure were conducted for various apple cultivars, including scald-sensitive and quickly softening cultivars such as ‘Granny Smith’ and ‘Golden Delicious’ apple fruit, ‘Conference’ pear fruit, ‘Liberty’ blueberry fruit and ‘Kordia’ sweet cherry.

Technology highlights

Excellent quality retention

Preserve key quality attributes such as firmness and color as good as with chemical treatment with ripening inhibitors such as 1-MCP up to 12 months of storage.

Reducing losses

Avoid losses due to occurrance of storage disorders such as rot or superficial scald in a non-chemical way. Use our OptiShelfTM service to simulate shelf life duration in the expected coldchain.

Energy saving

Due to decreaing respiratory heat production, our technology reduces energy consumption by 10% at conventional temperature. Our technology enables storage at 3°C higher temperature than usual esulting in 30% energy reduction.
