Wisconsin Patent of the Month – June 2025
A newly patented process could make farm-raised fish taste better and reduce food waste across the aquaculture industry. Exciton Clean LLC has been granted U.S. Patent No. 12336555, titled ‘Method and system for purging off-flavor compounds from farm-raised fish’, introducing a targeted way to remove unwanted earthy or musty flavors from fish before they reach consumers.
Targeting Taste with Precision
Off-flavors in farmed fish-caused by compounds like geosmin and MIB-are a long-standing problem for producers and consumers alike. This invention uses a controlled water recirculation system to reduce these compounds during the final stages of fish cultivation. Unlike conventional purging methods, which can be time-consuming and inconsistent, Exciton Clean’s approach improves both efficiency and flavor outcomes.
Real-World Benefits for Aquaculture
The system optimizes purging through filtration, temperature control, and water management, allowing fish to naturally shed off-flavor compounds. The design also reduces water usage and labor costs. For fish farmers, this means a more reliable product with a cleaner taste, and less waste from fish that would otherwise be rejected.
Better Taste, Lower Impact
This innovation supports a growing demand for sustainable, high-quality aquaculture. By improving taste without adding chemicals or extending processing time, the technology offers a practical solution for producers trying to meet consumer expectations while keeping operations efficient.
Exciton Clean’s patent could reshape how fish farms manage quality, with broader implications for food safety and environmental stewardship.
