en.Wedoany.com Reported - Swedish company Vitsab International has developed the Freshtag Flight Label, a color-changing label designed to track the temperature exposure of perishable foods in airline meals, aiming to reduce food waste.

The color-changing label utilizes a "traffic light" color-change technology, monitoring the packaging status at every stage from the preparation kitchen to the flight through a cumulative temperature tracking function. Green indicates safe conditions, yellow signifies moderate, and red denotes exposure to unsuitable temperatures. The color-changing label is designed for use in frozen, refrigerated, or passive kitchen storage environments and requires no tools or technical setup for use.

Staff can quickly assess product safety visually, unrestricted by language or location. Sealed, unused perishable foods can be transferred to subsequent flights or donated to charities, which is expected to reduce the carbon footprint. Furthermore, this color-changing label solution may also help airlines reduce onboard weight by replacing heavy cooling equipment with ambient temperature kitchen storage, thereby saving fuel.

The Freshtag Flight Label complies with the World Food Safety Guidelines for Airline Catering Step 25 CCP2 standard, as well as US FDA, HACCP, Codex Alimentarius, and ISO 9001 standards, and EU Regulation 852/2004. According to Vitsab, current airline catering clients report that the label is easy to use and provides clear information.

In terms of airline waste management, the Lufthansa Group previously partnered with WasteAid to promote the recycling of onboard items. Lufthansa Group flights generate approximately 15,000 kilograms of recyclable waste annually at Mumbai Airport.
