Abstract


The effects of a dose of 2.0 kGy (Co-60) and three ranges of storage temperature (0-4°C, 9-11°C, 18-19°C) on increasing the shelf-life and some quality properties of the mushrooms were investigated. The retardation of mushroom growth and ageing by ionizing radiation was estimated by measurements of the cap diameter, stem elongation, cap opening and discoloration of cap surface. The control of fungal and bacterial diseases was also evaluated. The effect of lower doses, 0.5 and 1.0 kGy, was compared at the storage temperature of 10°C.
The irradiation of mushrooms soon after harvest and storage at temperatures of 10 and 16°C allowed the retention of quality and increased the shelf-life to 8 days; at 18-19°C to 6 days.
