Across airlines, cruise lines, and rail services, onboard catering teams manage some of the most temperature‑sensitive products in the travel experience, where any break in the cold chain can lead to unsafe food, waste, and brand risk. Vitsab® International AB developed Freshtag® Time–Temperature Indicators (TTIs) to give operators a simple, visual way to monitor perishable items from production to service and demonstrate control of food safety and quality.
Freshtag Onboard Catering Labels help verify that chilled foods have been handled correctly in service and storage while supporting regulatory compliance, passenger confidence, and sustainability goals.
Visual Time–Temperature Monitoring at a Glance
Freshtag is a compact, color‑changing smart label, about the size of a postage stamp, engineered with product‑specific formulations that monitor the true time–temperature tolerances of each perishable item. Once activated, the label starts in green, then transitions to yellow and finally to red as cumulative exposure moves beyond validated limits for safety and quality.
This stoplight system turns complex time–temperature data into a clear visual cue that crew members, caterers, and inspectors can interpret at a glance, without specialized tools or extensive training.
Applied Across the Onboard Catering Journey
For onboard catering, Freshtag labels are applied to sealed perishable items such as chilled meals, dairy products, ready‑to‑eat snacks, and other regulated foods moving through aviation, cruise, and rail networks. The label travels with the product from production and packing to loading, in‑service storage, and final consumption or donation.
Because Freshtag tracks conditions over time, operators can see whether products stayed within limits across every leg of the journey, even after multiple handoffs and service cycles.
Supporting Regulatory Compliance in Multiple Jurisdictions
Freshtag Onboard Catering Labels are commonly accepted by food inspectors globally as a practical tool to monitor chilled foods in service and storage, helping operators meet World Food Safety Guidelines for Airline Catering step 25 (CCP2) and Codex Alimentarius HACCP monitoring requirements. They also align with ISO 9001, FDA food safety codes, and EU regulation 852/2004, so temperature control can be documented at critical points within existing Food Safety and Quality Management Systems without adding complexity.
Easy to Implement for Airlines, Cruise Lines, and Rail
Freshtag Onboard Catering Labels are designed for straightforward implementation across diverse service models, from short‑haul flights and regional rail routes to long‑duration cruises. The labels are simple to activate, store, and apply, and they can be read at any stage of the journey without specialized equipment.
This ease of use allows Freshtag to fit into existing standard operating procedures with minimal disruption, giving onboard catering teams a shared visual language for product status that can be adopted quickly across locations and partners.
By making the actual time–temperature history of each sealed perishable item visible, Freshtag helps operators reduce unnecessary food disposal and associated emissions. When labels confirm that products have remained within safe limits, airlines, cruise lines, and rail services can confidently serve them on the next flight, sailing, or route segment instead of discarding them preemptively.
Enhancing Passenger Experience and Trust
Food quality and safety are central to how passengers perceive the overall travel experience, whether they are flying, cruising, or traveling by rail. By communicating that perishable items are monitored by Freshtag Onboard Catering Labels, operators provide clear, science‑based reassurance that complements existing food safety measures.
This transparency supports stronger brand trust and can help differentiate catering programs, showing passengers that product quality and safety are actively managed from production to service.
Backed by Scientific Expertise and Industry Recognition
Vitsab International AB positions Freshtag as a research‑ and development‑driven solution, collaborating with regulators, academia, and industry to advance food safety innovation. Company roles emphasize scientific and business development expertise, reinforcing its position as a technical authority rather than a conventional vendor.
For more than 20 years, Vitsab has developed proprietary, trademarked Freshtag formulations for onboard catering, home delivery, caviar, and dairy, earning the 2023 IAFP Global Food Safety Innovation Award and strong credibility with regulators and industry leaders. Freshtag Onboard Catering Labels turn that expertise into a visible proof point that protects product quality, supports sustainability, builds passenger trust, and allows operators to confirm safety in seconds at every handoff.
