Abstract

Vitamin D 2 is essential for the human body and mushrooms are proved to be one of the best sources of it. In our experiment biologically active, pre-harvest white and cream type button mushrooms and oyster mushroom were treated with UVB light in order to increase their vitamin D 2 level, by transforming their natural ergosterol content into vitamin D 2. UVB lamps (operating on 312 nm) and six time periods of irradiation (15 to 90 min) were used. After three consecutive days of treatments the yield were measured and samples were taken for vitamin D 2 analysis. Data showed considerable increase in vitamin D 2 levels at every time period in each cultivar.
