Vitsab® International AB has unveiled Freshtag®, a color-changing time-temperature monitoring label designed to provide visual assurance of food safety and quality throughout the cold chain, from dispatch to delivery.

The device, developed by Vitsab International AB, is positioned as a simple, cost-effective solution for monitoring cumulative time and temperature exposure in perishable foods. Freshtag is engineered to indicate whether products have remained within predefined temperature limits during storage and transport, addressing a persistent challenge for chilled and frozen food categories.

At the core of the system is what the company describes as “Stoplight Technology,” a visual indicator that progresses from green to yellow and then red if temperature abuse occurs according to product-specific guidelines. The color-change mechanism is intended to allow instant verification of cold-chain compliance without the need for scanners, software, or technical setup. According to the company, the label can be validated “at a glance,” regardless of language or location.

Freshtag is designed to integrate into existing food safety and quality management frameworks. Vitsab states that the solution is compliant with FDA, EU, HACCP, and ISO9001 requirements and can be used across refrigerated, frozen, or passive storage environments. Labels are supplied ready to use and applied directly to packaging, enabling cumulative temperature tracking along the entire supply chain rather than point-in-time measurements.

The company positions the solution as particularly relevant for foodservice operations, catering, retail distribution, e-commerce packaging, and home delivery. In these channels, products may pass through multiple handling stages, increasing the risk of temperature deviations that can compromise quality, shelf life, and safety. By providing a visible record of temperature exposure, Freshtag aims to help operators identify compromised products before they reach customers.

Beyond compliance, Vitsab emphasizes the commercial implications of temperature monitoring. The company says the system can reduce replacement orders and refunds by flagging integrity issues early, while also increasing customer confidence and satisfaction. The visual nature of the indicator is intended to reinforce trust in food quality and safety, particularly in premium or high-value segments where brand reputation is closely tied to product integrity.

Vitsab reports that Freshtag has already been adopted across a range of applications, from professional kitchens to last-mile delivery. The company notes that users consistently rate the system highly for ease of use and clarity, citing the straightforward messaging delivered by the color-change format. The label remains visible throughout the product’s journey, providing what Vitsab describes as “full-history quality monitoring” rather than retrospective data analysis.

Founded as a research-driven organization, Vitsab has focused for more than two decades on visual freshness and safety indicators. The company states that Freshtag’s technology has been validated through collaboration with regulators, academia, and industry partners, and that its stoplight-based approach has been recognized by international food safety bodies.

While Freshtag is presented as a universal cold-chain solution, its relevance is strongest in segments where temperature sensitivity is critical and distribution complexity is high. For processors and distributors of chilled or frozen foods, including value-added potato products, the technology offers a visible method of verifying cold-chain performance and supporting quality assurance strategies without adding operational complexity.
