2006-10-27 News Release
Chemicals company introduces shelf life indicators for perishable foods Ciba Specialty Chemicals and FreshPoint present OnVu, the revolutionary new time temperature indicator system that shows the freshness of perishable goods at a glance.
At Stand B 069 in Hall 4 at the Emballage
The most common causes of spoilage of chilled food and beverages are
too high temperatures during storage and transport. OnVu TTIs allow producers,
retailers and consumers to check whether perishable products have been
correctly stored and supplied, thus helping to enhance consumer convenience
and confidence, strengthen the reputation of brands using them and optimize
shelf life. OnVu TTIs are supplied either as printing inks or labels and can in principle be used for any product that is sensitive to temperature. They give a visual summary of a product’s accumulated chill-chain history, recording the effects of both time and temperature. Every indicator is tailored to the shelf life and optimum storage conditions of the product it is designed to monitor. By providing essential information on chill-chain history, OnVu TTIs also help to optimize shelf life, since suppliers and retailers will no longer need to discard products prematurely to cover for potential spoilage, caused, for example, by incorrect storage. OnVu TTI technology relies on the properties of pigments that change
color over time and when temperatures fluctuate. The label or display
consists of a reference color and an OnVu TTI. Once activated by a suitable
light source, the TTI first becomes dark and then grows progressively
lighter as time passes and also if and when the ambient temperature rises.
Exposure to higher temperatures than those prescribed, therefore, accelerates
the lightening process
of the color. When the activated color attains the same shade as the reference,
the product has reached the end of its shelf life.
