“…A potentially attractive option is exposure to ionizing radiation since previous reports have suggested that irradiation treatment is highly effective in inhibiting physical changes associated with postharvest deterioration and maintaining a fresh product appearance (Kader, 1986). Doses of g-irradiation inhibited cap opening, stalk elongation and browning, reduced the level of microbial contamination, and generally extended the shelf life of A. bisporus, with no detectable impact on organoleptic attributes (Gill, Nicholas, & Markakis, 1969;Lescano, 1994). Furthermore, g-irradiation extended the storage life of Pleurotus sajor-caju (Roy, Chatterjee, & Bakukhandi, 2000) and Pleurotus pulmonarius (Xia, Xiong, & Jiang, 2005) without adversely affecting key nutritional components.…”

“…S liced mushrooms are highly perishable and have a limited shelflife, usually only 7 to 9 d at 4 °C. Accelerated physiological, morphological, and microbial changes lead to browning and sliminess as well as early breaking of the veil, expansion and darkening of the cap and gills, and elongation of the stem (Lescano 1994;Eastwood and Burton 2002). The short shelf-life of mushroom slices is an impediment to the distribution and marketing of the fresh product.…”

The effect of electron-beam irradiation on microbial counts, color, texture, and enzyme activity of mushroom slices was evaluated at dose levels of 0.5, 1, 3.1, and 5.2-kGy. Irradiation levels above 0.5 kGy reduced total plate counts, yeast and mold, and psychrotrophic counts to below detectable levels and prevented microbial-induced browning. Firmness of all samples was similar during storage except for the 5.2-kGy sample. Color was preserved by irradiation as evidenced by the higher L* values. Electron-beam irradiation at these levels did not affect the polyphenol oxidase activity. Irradiation at 1 kGy was most effective in extending shelf-life of mushroom slices.

“…Beaulieu et al (2002) also reported the benefit of preserving irradiation on the mushroom A. bisporus reporting that the useful life was extended to 4 days with a dose of 4500 Gy of irradiation. Also, Lescano (1994) reports that the dose of 3000 Gy, combined with Poly-Vinyl Chloride (PVC) film packaging and storage of 10 ± 2°C, increased the shelf life of mushrooms A. bisporus, providing a white color retention, and growth and the opening of the pileus, acceptable for commercialization for 11 days and for consumption up to 16 days of storage.…”

We evaluated the effect of gamma irradiation doses (0, 125, 250, and 500 Gy) in control of psychrotrophic bacteria in different strains of Agaricus bisporus (ABI-07/06, ABI-05/03, and PB-1) during storage, cultivated in composts based on oat straw (Avena sativa) and Brachiaria spp. The experimental design was completely randomized in a factorial scheme 4  2  3 (irradiation doses  composts  strains), with 24 treatments, each consisting of 2 replicates, totaling 48 experimental units (samples of mushrooms). The mushrooms collected from all culture conditions were packaged in plastic polypropylene with 200 g each and subjected to Cobalt-60 irradiator, type Gammacell 220, and dose rate 0.740 kGy h -1 , according to the treatments. Subsequently, the control (nonirradiated) and other treatments were maintained at 4 ± 1°C and 90% relative humidity (RH) in a climatic chamber to perform the microbiological analysis of mushrooms on the 1st and 14th day of storage. According to the results, it was found that the highest mean colony psychotrophic count, after 14 days of storage, was observed in strain ABI-07/06 1.30 × 10 8 g -1 most probable number (MPN) in nonirradiated mushrooms, coming from Brachiaria grass-based compost, and this same strain under the same storage conditions, coming from the same type of compost that underwent a dose of 500 Gy, obtained a significant reduction in mean colonies of psychrotrophic bacteria (2.25 × 10 4 g -1 MPN). Thus, the irradiation doses tested favored reducing the number of colonies of psychrotrophic bacteria, regardless of the type of compound and strain of A. bisporus.
