Nutritive Evaluation and Trace Metal Contents of Commercial Edible Mushroom –Agaricus bisporus

Two different Agaricus bisporous samples were analysed for their proximate composition, mineral contents, contribution to daily intake and comparing their results with the recommended daily intake levels were successfully achieved.Proximate composition study shows that these species are with rich sources of Protein, Carbohydrate and Fibre with low fat content.Mineral element analysis reveals the significant role of the elements, daily intake limits and toxicity level of the elements observed in the present study.According to the present study, the observed mineral elements are 0.57-0.61(As), 0.15-0.24(Cd), 0.09 (Co), 6.84-7.12(Cu), 87.33-92.56(Fe), 0.26-0.29 (Pb), 13.14-14.56(Mn), 18.05-19.11(Ni), 1.12-1.35(Se), 39.81-40.27(Na)and 60.61-62.34(Zn) mg/kg DW.These values are all within the permissible limits recommended by World Health Organization and no potentially harmful mineral element levels observed.
