Mushroom growers can now use UV light to boost vitamin D, not just UV lamps
What happened
US health regulators are considering a new way to produce vitamin D2 mushroom powder. This change would allow mushroom growers to use a broader range of UV light sources, not just specific UV lamps, to increase vitamin D levels in their products.
Why it matters
For years, the rules specified a particular type of UV lamp for boosting vitamin D in mushrooms. This meant growers had limited options and potentially higher costs for specialized equipment. The proposed change opens the door for more flexible and potentially cheaper methods, like using sunlight or other broad-spectrum UV sources, to achieve the same nutritional benefit.
The signal
Watch for the final rule and whether mushroom producers quickly adopt new UV treatment methods, or if the industry sticks with existing equipment.
