Method for preventing the formation of spots at the surface of mushrooms and mushrooms thereby obtained

摘要

The invention relates to a method for preventing at least the formation of spots at the surfaces of edible mushrooms such as ordinary button mushrooms. Further, the invention relates to mushrooms with a longer time of sale. By means of the invention, it has appeared possible to prolong the period between harvesting and the formation of a substantial amount of brown spots at the surface of a number of mushrooms of good quality by more than a week with respect to unthreaded mushrooms. The mushrooms are exposed to UV-light.
