Cold plasma for grain decontamination and mycotoxin reduction
The University of Alberta has developed atmospheric cold plasma technology to decontaminate grains like wheat and barley by reducing harmful mycotoxins and fungi, while also enhancing seed germination. This innovative low-temperature process offers an effective, environmentally friendly solution for grain safety and preservation.
The University of Alberta's atmospheric cold plasma system is a validated technology that effectively reduces mycotoxins such as deoxynivalenol (DON), T-2, and HT-2 in grains like wheat and barley. The process involves treating grains with low-temperature plasma, which degrades toxins and molds without damaging seed viability. Studies have shown that treatments of 6 to 10 minutes can decrease mycotoxin levels by up to 54%, while also improving germination rates. This technology is particularly relevant for pre-storage decontamination and low-temperature preservation, providing a safer and more sustainable approach for the grain industry. The university's research highlights the potential for this method to enhance food safety, reduce economic losses, and support agricultural productivity.
