Customers can purchase land recently farmed mushrooms to be by irradiation with UV light as a rule, the rights of a Vitamin D-bombs. Whether the newly developed method works, and given Vitamin-D-levels, the Foundation were tested.
On the packaging the country of purchase mushrooms you read "Vitamin D mushrooms to support healthy bones and Zähne". More concretely, the label promises that the mushrooms should provide thirty times more Vitamin D than conventional cultivated mushrooms. The promise: a Hundred grams to contain 125 percent of the recommended daily dose of Vitamin D. For two euros you get even more – namely, 200 grams of the country of purchase mushrooms.
In the winter months many people suffer from Vitamin D deficiency
The most Important fact: mushrooms contain even without additional UV irradiation, the fourth fungus is already Vitamin D. The proportion of cultivated only significantly lower than in wild-growing mushrooms. High-fat species of fish, such as herring and salmon are considered to be foods with the highest levels of Vitamin D. Ten to twenty percent of the Vitamin D supply in the human being takes on the food. The main supplier, however, remains the light of the sun in the summer months, which can save the body as far as possible through the winter months.
"Just now in the dark Season, many people suffer from a Vitamin D deficiency. Because the UVB-component in sunlight is too small for their Vitamin D production in the Haut", food scientist Paul Urbain says. Stone mushrooms are but especially for vegetarians and Vegans with the ideal possibility of their Vitamin D requirements easily and taste to cover full
The scientists at the University hospital in Freiburg, has now developed the procedure, in which brown mushrooms light will be illuminated for a short time with UVB.
The results of Stiftung Warentest
Stiftung Warentest has taken the souped-up mushrooms under the magnifying glass. For the Test, seven packs of " were;Super-Pilze" tested and Vitamin D levels compared.
The result: The purchase of land fungi and achieved a Vitamin D level of 9.3 micrograms per 100 grams. Ordinary mushrooms a Vitamin was determined to be D-content of 0.3 micro-grams per 100 grams.
The promise on the package that the mushrooms thirty provide times more Vitamin D than conventional mushrooms was observed.
Vitamin D content varies depending on the package
The testers noted, however, that the Vitamin D content will vary in the case of the tested packages, which are marked with 6,25 micrograms per 100 grams. The lowest content was measured in a pack of 5.3 micrograms of Vitamin D. Other mushrooms from another pack had reached the maximum value of 15.1 micrograms. This value even exceeds the maximum level, the EU has set for these novel foods under the European Novel Food regulation: 10 micro grams per 100 grams.
However, you can also take advantage of the Vitamin-D-rich mushrooms multiple daily packs – an Overdose of Vitamin D should not be feared, according to Stiftung Warentest.
Another point of criticism, in addition to the widely varying levels of Vitamin D in the different packs was that the mushrooms were not specifically named. The Novel Food regulation requires that breeding in mushrooms treated with UV-radiation, "UV-treated Pilze" hot. However, on the label only the name " are;Vitamin D Pilze" and "Kulturchampignon".
