| description | Mushrooms of the Pleurotus spp. are very sensitive and the shelf-life of mushrooms is limited, that is a few days under
normal or low temperatures, which is a limitation in the distribution and marketing of fresh products. To extend their shelf
life, drying methods need to be applied. Total drying time decreased with increased drying temperatures (960 and 330 min of
drying at 40 and 70°C, respectively). The drying curve equations is establised as y=a.exp(-kt) (R2>0.95). These equations
can be applied to predict moisture reduction during drying of Pleurotus spp. at the temperature ranges studied. Besides,
effect of drying methods (convection, sun and solar drying) was investigated. Results showed that the quality of sample
treated with solar drying was higher than others. In the solar drying samples, the highest protein, carbohydrate, flavonoid,
β-glucan content (in dry basis) were 16.22%, 24.84% and 5.82 mg QE/gm, 0.41%, respectively. The antioxidant capacity
(FRAP and DPPH) was 362.58 mM Fe2+/gm and 62.35%, respectively. The lighter color was obtained for the mushroom
dried using a solar dryer. |
