Evaluation of different methods of drying on the quality of oyster mushroom (Pleurotus sp.).

Mushrooms are extremely perishable and have a short shelf life. To increase the postharvest life, different methods of drying (sun drying, fluidized bed drying and thin layer drying) were tested, plus pretreatment by blanching or soaking in 0.5-1.5% potassium metabisulphite (KMS) solutions. The quality of Pleurotus mushrooms pretreated with 0.5% KMS and dried in fluidized bed at 50 deg C for 80-120 min was found to be superior to other drying methods. Rehydration ratio was also maximum in KMS-treated mushroom with no significant difference between concentrations. The treatment with KMS or blanching lowered the nutritive quality but improved the colour of the mushrooms when compared with sun-dried samples. Storage of mushrooms after treatment with KMS at higher concentration (1.5%) reduces the microbial spoilage.
