On December 2018 Packaging World magazine edition, Matthew Reynolds wrote about the new technology from another emerging player in the market. Senoptica Technology identifies defective gas-flushed meat and poultry packs using and ink-based sensor printed directly into the MAP lidding film laminate. Once the product has been packed, the sensor is scanned using the Senoptica scanning system. On scanning, the sensor will appear a different color, depending on the oxygen level within the pack.


"This is revolutionary because, right now, food manufacturers can only do a destructive test on a tiny proportion of the packs produced to ensure that they are produced to specification" says Brendan Rice, CEO of Senoptica, to PW Magazine. The benefits are: increased category sales, reduced food waste, reduced production costs and improve compliance. "What having a sensor printed into the packaging allows is sensor imaging as , for instance, retailers do stock rotations on the shelves of the supermarkets", Rice says. If we take the beef as example, once the oxygen in the pack dips under 55% oxygen, the meat will go brown within 24 hours. "If pack is at 60% oxygen, the retailer can choose to to move it to a featured spot. It also presents them the opportunity to mark it down for quicker sale".


This technology isn't designed to be an extension of the label for consumers to use on their refrigerators. The real value of these technologies are entirely in the logistics and inventory for the handshake between the food manufacturer, any distributors that might take custody, and the retailer.
