The effects of carrageenan, carboxymethyl cellulose solution and their complex film on the physiology and quality of mushrooms stored at (2±1) ℃ were studied. The minimum loss of weight was obtained in fruits coated with CMC coating, the minimum value of respiration rate, PPO activity, membrane permeability and the maximum hardness and L* value were obtained in mushrooms coated with carrageenan coating. Overall, the preservation effect of carrageenan film is the best, and it can extend the shelf-life of Agaricus bisporus to more than 12d.
