Innovative, non mechanical, food sensors allowing 100% control on gas composition and (micro) leaks of products packed under modified atmosphere.
Modified atmosphere packaging (MAP) is the replacement of air in a pack with a single or a mixture of gases. MAP packaging is a technique to extend shelf life of products.
In the long path from producer to consumer lots of things can go wrong with the MAP packaging and therefore also with the product itself: the package can be damaged during transportation, incorrect use in the supermarket, but also wrong tuning of the packaging process. It is estimated that 30 to 35% of MAP packages are not properly packed due to incorrect sealing and / or erroneous gas composition.
SensorSpot has developed a smart foil with an integrated oxygen sensor that can determine whether the food product is properly packed. The sensor consists of a luminescent spot integrated in a gas tight foil. Since the spot is integrated inside the foil the spot cannot come into direct contact with the food. Oxygen permeability of the inside layer permits oxygen molecules to pass this layer and reach the sensor. SensorSpot also developed a measuring unit capable to measure the luminescence levels with high accuracy at a distance of 10 cm. The package condition is determined by means of intelligent software and the device will indicate a right or faulty gas composition.
Combining sensor and measuring device makes it possible to check each package in a non - invasive manner!
