Button mushrooms (Agaricus bisporus) were dipped for 2 min in different concentrations (1%, 2% and 3%) of alginate, then placed in jars and ventilated continuously with 100% O2 for up to 16 d at 4 °C. Mushroom respiration rate, weight loss, texture, color, percent open caps, chemical properties and activities of polyphenol oxidase (PPO), and peroxidase (POD) were measured. The results indicate that treatment with alginate coating (2%) + 100% O2 maintained a high level of firmness, and delayed browning and cap opening. In addition, alginate coating (2%) + 100% O2 also delayed changes in the soluble solids concentration, total sugars and ascorbic acid, and inhibited the activity of PPO and POD throughout storage. Our study suggests that the use of alginate coating under a high oxygen modified atmosphere has the potential to maintain button mushroom quality and extend its postharvest life to 16 d.
► Alginate coating (2%) + 100% O2 maintained a high level of mushroom firmness, delayed browning and cap opening.
► Alginate coating (2%) + 100% O2 also delayed changes in the soluble solids concentrations, total sugars and ascorbic acid.
► Alginate coating (2%) + 100% O2 inhibited the activity of PPO and POD during mushroom storage.
