dc.description.abstractVitamin D2 content significantly (p<0.0001) increased over control in Button and Oyster mushroom when exposed for 30 minute to UV-A, UV-B and UV-C at distance of 60cm. No significant effect was observed on protein, crude fat and crude fibre content of Button mushroom, while a significant (p<0.005) increase in ash was seen. UV treatment in Button mushroom significantly (p<0.05) decreased oleic acid, with a significant (p<0.05) increase in linoleic acid. In case of Oyster mushroom UV treatment significantly (p<0.05) increased palmitic acid, stearic acid and oleic acid, while linoleic acid was significantly lower. The in vitro protein digestibility was significantly (p<0.01) increased over control in both Button and Oyster mushroom by UV treatment along with significant (p<0.0001) increase in total phenols. Amongst minerals: copper content (p<0.0001), phosphorus and potassium (p<0.0001) and zinc (p<0.05) significantly increased by UV treatment in both mushroom varieties. The products prepared by incorporating treated Button and Oyster mushroom powder were highly acceptable at the level of 10% and 15% respectively. These products had higher protein (p<0.05), ash (p<0.05), fibre (p<0.05), in vitro protein digestibility and total phenol content. The mineral content viz., iron, copper, phosphorus, potassium, zinc and selenium were significantly (p<0.05) higher in UV treated products. Microbial growth was recorded in UV treated mushroom powder stored for 90 days with no bacterial and fungal growth, similarly Panjiri and Mathi could be stored for 105 days without bacterial or fungal growth. Storage in air tight glass container was best as compared to other packaging materials.en_US
