UV-irradiated mushrooms, enriched in vitamin D2, may improve vitamin D status in individuals with low but not high vitamin D status: new data from an ODIN systematic review and meta-analysis
There is a considerable mismatch between current intakes of vitamin D by many European populations and recommended target intakes for the vitamin [1]. While traditional fortification of milk and other dairy products remains important in tackling inadequate intake, additional strategic approaches to fortification, including biofortification, of a wider range of foods, have the potential to incre...
متن کاملStatistical Optimization of Ultraviolet Irradiate Conditions for Vitamin D2 Synthesis in Oyster Mushrooms (Pleurotus ostreatus) Using Response Surface Methodology
Response surface methodology (RSM) was used to determine the optimum vitamin D2 synthesis conditions in oyster mushrooms (Pleurotus ostreatus). Ultraviolet B (UV-B) was selected as the most efficient irradiation source for the preliminary experiment, in addition to the levels of three independent variables, which included ambient temperature (25-45°C), exposure time (40-120 min), and irradiatio...
متن کاملPhotobiology of vitamin D in mushrooms and its bioavailability in humans
Mushrooms exposed to sunlight or UV radiation are an excellent source of dietary vitamin D2 because they contain high concentrations of the vitamin D precursor, provitamin D2. When mushrooms are exposed to UV radiation, provitamin D2 is converted to previtamin D2. Once formed, previtamin D2 rapidly isomerizes to vitamin D2 in a similar manner that previtamin D3 isomerizes to vitamin D3 in human...
متن کاملIncrease of vitamin D2 by UV-B exposure during the growth phase of white button mushroom (Agaricus bisporus)
BACKGROUND Mushrooms are the only non-animal food source of vitamin D. Wild mushrooms have naturally high vitamin D(2) content, and cultivated mushrooms produce vitamin D(2) from ergosterol when exposed to supplementary UV-B during the post-harvest phase. OBJECTIVES This study investigated the effects of providing supplementary UV-B during the growth phase on vitamin D(2) formation and the in...
متن کاملBioavailability of vitamin D2 from irradiated mushrooms: an in vivo study.
Vitamin D2 from irradiated edible mushrooms might present a possible dietary source of this vitamin, subject to its bioavailability. Having previously optimized a method for the conversion of ergosterol in mushrooms to vitamin D2, this paper examines the vitamin D-enriched mushrooms (Lentinula edodes) for their bioavailability of the vitamin, using an animal model. Thirty male Wistar rats were ...
