A fast, portable colorimetric screening solution designed to detect illegal formalin residues in seafood, processed meats, and agricultural produce within 30 minutes.

GUANGZHOU, China — As global food safety regulations tighten, detecting illegal chemical additives in food supply chains has become a top priority for seafood processors, wholesalers, and regulatory authorities. FSTest is proud to showcase its High-Sensitivity Formaldehyde Rapid Test Kit (Product Code: 24126)—an advanced, portable screening tool engineered to safeguard raw materials and rehydrated foodstuffs from illicit preservation.

Formaldehyde (commonly known as formalin) is a toxic compound unlawfully used by some suppliers to artificially firm textures, enhance appearance, and extend shelf life. Commonly found in illegally treated silverfish, squid, beef tripe, and rehydrated vegetables, formalin poses severe health risks, including acute gastrointestinal irritation and cell toxicity. FSTest's rapid testing solution enables immediate on-site verification to stop adulterated goods before they reach consumers.

Achieves trace-level detection thresholds—down to 0.2 ppm for liquid samples and 2 ppm for solid food matrices.

Replaces bulky laboratory equipment. All reagents and tubes are self-contained, allowing quality control teams to perform tests directly at receiving docks, wholesale markets, or border checkpoints.

Utilizes chemical color development where formaldehyde converts colorless extraction solutions into a distinct purplish-red shade, making result interpretation simple and visual against a standard color card.

Fully validated for rehydrated seafood (squid, silverfish), processed meats (beef tripe), agricultural produce (bamboo shoots), and soaking liquids/brines.

Designed for easy integration into daily food safety workflows across:

Eliminate chemical adulteration risks in your supply chain with FSTest's reliable rapid testing kits.
