Ethylene is the saviour and devil of fruit and vegetable ripening – this gaseous plant hormone ripens product for display – but then they over ripen and between 20 and 80 per cent of all post-harvest fresh fruits and vegetables have to be thrown away. The key to reducing this waste is testing the amount of ethylene that flows through (permeates) either into or out of the product‘s packaging.
Versaperm’s vapour permeability measurement system measures this to an accuracy in the Parts Per Million (PPM) to PPB range – and can do it over a wide range of environmental conditions.
The equipment is fast and simple to use and offers automated computerised control through a simple touch screen. Although it is often used on samples of the packaging, it also works with complete packages, multi-layer laminates and even coatings such as wax. It measures the permeabilities of several samples or packs at the same time and results can be available in as little as thirty minutes in some cases.
In addition to measuring ethylene permeability, the Versaperm equipment can optimally measure the permeability of any other gasses relevant to shelf-life and quality – including water vapour, oxygen, carbon dioxide, nitrogen and hydrocarbons.
The company also offers both a laboratory-based permeability testing service and a vapour permeability consultancy.
