Effect of different pretreatments on the quality of mushrooms during solar drying

Abstract

Freshly harvested mushrooms are highly perishable because of high moisture content metabolism and susceptible to enzymatic browning. Mushroom is a fungal fruiting body which is cultivated throughout the world. Effect on quality of dried mushrooms was studied for various chemical pretreatments viz. 1.0% potassium metabisulphite, 0.5% citric acid, 0.5% potassium metabisulphite + 0.2% citric acid, control and low cost drying methods viz. domestic solar dryer, medium size solar dryer and open sun drying. It was observed that application of 1% potassium metabisulphite treatment prior to drying using medium size solar dryer gave best quality dried mushrooms with results in accordance with statistical analysis. The drying time and final moisture content was also comparatively less than the mushrooms dried under shading plates and open sun drying.
