Abstract

Highlights: The quality deterioration of mushroom had been alleviated by C/Z/T films. C/Z/T films had improve the antioxidant properties of mushroom. C/Z/T films were a novel packaging material. Abstract: In this work, we have explored a new packaging material for the shelf life extension of Agaricus bisporus . The influence of active chitosan/zein films containing α-tocopherol on the physicochemical properties and enzyme activities of mushroom during the storage at 4 ℃ for 12 d was investigated. Mushroom packaged with chitosan/zein/α-tocopherol (C/Z/T) film showed the lower weight loss, relative leakage rate, browning index, respiration rate, polyphenol oxidase, peroxidase activity and malondialdehyde content compared with control, chitosan film and chitosan/zein film. In all treatment groups, mushroom treated with C/Z/T film showed the highest firmness, catalase, superoxide dismutase activities, total phenolic content and DPPH radical scavenging activity. The results implied that C/Z/T film could improve the antioxidant properties and maintain the quality of mushroom.
