Drying Process

When harvested mushrooms are exposed to sunlight during the summer, they begin to naturally produce vitamin D in large quantities. The explanation is that UV light converts ergosterol, a naturally occurring substance in mushrooms, into ergocalciferol (vitamin D2). Solar drying produces safe and high-quality dried mushrooms with great taste and enhanced flavor that can be used all year. As a result, dried mushrooms have the potential to serve as an excellent natural source of vitamin D during the winter months.

DIRFIS MUSHROOMS pioneering once again as Europe's first company to market dried mushrooms with high vitamin D levels. Our solar-dried "My delicious OYSTER MIX" consists of golden and grey oyster mushrooms that were organically grown on our farm on the Greek island of Euboea, far from any industrial activity and surrounded by organic olive groves. The dried mix contains over 2100μg of Vitamin D2 per 100g, making one or two mushroom slices sufficient for the recommended daily intake. Solar-dried mushrooms are the only source of vitamin D for vegans.
