The aim of the study was to evaluate the effect of MAP and film thickness on Agaricus bisporus quality. Three initial gas compositions: high oxygen packaging (100% of O 2 ); medium oxygen packaging (50% O 2 , 50% N 2 ); low oxygen packaging (5% O 2 , 5% CO 2 , 90% N 2 ) and two types of polyethylene films of 54 and 39 µm thickness were used. The samples were stored at 4 ± 1C for 14 days. The films and MAP had a significant effect on color and weight loss of the mushrooms. In the case of texture, the gas composition alone exerts a significant effect. The optimal conditions for prolonging the shelf life of mushrooms were found for packaging with medium oxygen level and film of higher permeability. In optimal conditions, mushrooms were characterized by lightness of 93 and 85, and a browning index of 11 and 23 in 0 and 14 days of storage, respectively. Practical Application White button mushrooms are highly perishable. The average storage time of fresh mushrooms does not exceed 4 days. There is a pressing need for effective methods to extend the shelf life of these mushrooms. According to the presented results, it is possible to maintain the product visually acceptable up to 14 days for mushrooms packed with the usage of a 39 µm thick film type and modified atmosphere with a medium level of oxygen (50%).
