SensorSpot is an engineering company with a focus on design, development and production of hardware and software for physical and (bio) chemical sensors for non-destructive detection of gases in MAP applications in food industry.
SensorSpot from Wijchen, the Netherlands has developed a cost-efficient and flexible non-invasive system for measuring the oxygen level in individual units of packaged foods. The system consists of a sensor with a special pigment, which is printed on the inside of the packaging material, and a reading device that can quickly check whether the packaging atmosphere is still intact without puncturing the packaging film. The sensor spot is a mere 5-10 micrometers thick. It contains fluorescent and oxygen-sensitive dyes covered by a thin oxygen-permeable laminate. None of this comes into contact with the food product. SensorSpot developed this system in collaboration with AFP Holland film suppliers and software supplier Intemo. Worldwide, approximately 400 billion food products are MAP (modified atmosphere) packaged every year to increase their shelf life. In an estimated 15% of cases there is something wrong with the sealing or the gas mixture. This can result from damage incurred during transportation and storage or from incorrectly adjusted settings in the packaging process. Traditional checks require packages to be punctured (invasive check). Faulty packaging can cause the rejection of entire batches because of oxygen ingress. According to judges’ panel, the SensorSpot system is an excellent way to ensure that fewer products end up in the waste bin. “It is a simple, but very effective method that does not cost much.”www.sensorspot.nl
