15%和10%。 An L9(3)4 orthogonal test was carried out to evaluate the storage quality of Agaricus bisporus under active modified atmosphere packaging with different temperature, packaging material, O2 and CO2 volumetric concentrations. Weight loss, fructification firmness, degree of browning, the respiration rate, membrane permeability, soluble solid content, polyphenoloxidase (PPO) and peroxidase (POD) activity of Agaricus bisporus were determined on the 3th day, 5th day, 7th day, 9th day, 11th day after storage, respectively. Study results suggested that, storage temperature was the most important factor affecting the storage quality of Agaricus bisporus, and a low storage temperature was essential to the preservation of Agaricus bisporus; the optimum treatment of active modified atmosphere packaging for Agaricus bisporuswas that storage temperature 2℃,packaging material PVC2, 15% O2 volumetric concentration, 10% CO2 volumetric concentration.
