How and when is OnVu™ activated?
An OnVu™ TTI is activated by a standard, commercially available UV light source (preferably light-emitting diodes known as LEDs) just
before application to the package. A filter is then added over the TTI to protect it from deliberate recharging.
How fast does the color react to temperature changes?
The TTI is calibrated to the shelf life and optimal storage conditions of every consumable product that it is designed to monitor.
Why are TTIs needed?
Temperature abuse is known to be the major cause of food spoilage and illness associated with it. TTIs show the consumer at a glance
whether the goods have been correctly supplied and stored. OnVu™ responds to an immediate consumer concern: reliable quality
assurance when purchasing and storing perishable goods.
What is the benefit of a TTI versus a “sell-by date” label?
The “sell-by date” label does not report the conditions in which the chilled product has been stored. The absence of time-temperature
history must therefore be taken into consideration when choosing a sell-by date. In order to have a safety margin, the suppliers are
obliged to reduce the shelf-life of perishable goods in order to compensate for any accidental or deliberate temperature abuse. This
‘rule of thumb’ method is neither accurate nor scientifically based. OnVu™ records the temperature history over time. This accurate record
shows whether the product is still suitable for consumption or not.
What ensures the consistency and quality of an OnVu™ TTI?
In order for OnVu™ to be released on the market, it first had to pass a series of rigorous tests. The approval process for the active pigment
is controlled by local authorities. Registration is only granted once the technology is considered to be scientifically sound and
of benefit to the consumer.
Which OnVu™ products have been developed so far?
Responding to an immediate need for effective, low-cost time-temperature monitoring, the first OnVu™ TTI is targeted at the meat and
dairy industries. Further OnVu™ TTIs are being developed for the medical industry: for blood products, vaccines and medication.
When is OnVu™ being launched?
The official launch of the first commercial OnVu™ product is 4 April 2006 at the Anuga FoodTec in Cologne, Germany.
Does the OnVu™ label require low-temperature storage?
No, the OnVu™ label or ink can be stored at room temperature and activated when required.
How much does the OnVu™ TTI cost?
It is the most effective technology available on the market and will not add significant cost to the package.
