A Case Study on Surplus Mushrooms Production: Extraction and Recovery of Vitamin D2

The presented case study illustrates the possibility of adding value to biological surplus remaining from mushroom cultivation industry. In essence, unused parts were submitted UV-C irradiation, with purpose increasing vitamin D2 content and validating its extraction. Vitamin concentration in three different species (Agaricus bisporus, A. bisporus Portobello, Pleurotus ostreatus) was obtained by high-performance liquid chromatography (HPLC), means an ultraviolet (UV) detector. method validated using Portobello sample, reproducibility accuracy confirmed. Independently irradiation dose, effect on significant, allowing it increase less than 4 µg/g dry weight (dw) more 100 dw all species. These results are good indicators feasibility industrial mushrooms as sustainable food sources, besides contributing strengthen circularity principals associated production chain.
