Abstract
In this study, quality of white button mushrooms (Agaricus bisporus) treated by water and citric acid was evaluated during storage at 2 temperatures (room temperature and 4°C). The effect of modified atmosphere packaging (MAP, by 4±1% CO2, 6±1% O2 and the remaining N2) with or without water absorbent (silicagel) was also evaluated. Samples were assessed for their organoleptic properties (texture, color and spoilage), colorimetery and respiration rate during 12 days of storage. Results showed that among all treatments, water treated samples packaged with MAP method contained silicagel sachet and also stored at refrigerator obtained the most organoleptis scores. This sample retained the optimum level of inter packaging gas composition and finally the best storage time was determined as 8 days.
