Enhancement in physicochemical parameters and microbial populations of mushrooms as influenced by nano-coating treatments

Abstract White button mushrooms are greatly high perishable and can deteriorate within a few days after harvesting due to physicomechanical damage, respiration, microbial growth of the delicate epidermal structure. For that reason, the present research work was applied to evaluate the effect of chit...
