Abstarct: Edible mushrooms are an important source of food and protein. Post-harvest losses are causes for the decline in production and exports at fresh product foods. One way to increase food, reduce post-harvest losses especially in mushrooms. Many solutions used to reduce post-harvest losses that use the modified atmosphere and edible coatings are important in post-harvest industry. The use of edible coatings according to culture conditions and the mushrooms type must be carefully designed. Inappropriate selection may be ineffective or Shelf life of the product due to reduced tissue damage; and to create conditions for anaerobic respiration and reduces the flavor of the product. To study this subject in mushroom, an experiment was carried out as factorial baxsed on randomized complete design with three replications in 2015, at horticultural labrotry of Shahrood University. The investigated factors were packaging in 5 parts (Control, Polyethylene 20 mm, Polyethylene 40 mm, Oriental polypropylene 20 mm and Nano-composit clay 3%), Echinophora’s essential oil (0, 50 and 100 ppm) and sampling treatment (Seven samples within 5 days). In this study, essential oil decrease weight, microbial population and the radiance. The level of 50 ppm essential oil were increase hardness, hydrogen ion concentration, Delta-E and marketable yield, the OPPning of cap, changing the color, texture, wrinkles, texture, smell and taste. Also essentioal oil were reduce the catalase and malondialdehyde enzymes. On the other hand, the use of packaging films, especially Nano-composite clay 3% were improve weghit losses, hardness, total soluble solid, titrable acidity, hydrogen ion concentration, brightness, light intensity, marketability, OPPn cap mushrooms, change the color, smell, taste. As a result of research, combin treatmens of Nano-composite clay 3% film and the essential oil 50 ppm can be described as a combination of appropriate treatment.
