Quality attributes of Pleurotus eryngii following gamma irradiation

Absorbed‐dose estimation and quality attributes of gamma‐irradiated fresh shiitake mushrooms

“…The potential of E-nose analysis to screen irradiated samples such as irradiated tomatoes, 20 anchovy sauce 21 and red pepper powder 22 has been reported. The successful discrimination of irradiated mushrooms (Pleurotus eryngii), due to the change in volatile profiles upon irradiation, was also reported by Akram et al 15 using the E-nose analysis.…”

“…However, irradiation at comparatively higher doses can affect pigment cells, resulting in a change in color attributes, and membranous structures resulting in leakage of cell fluid . Similar drastic effects of irradiation were observed upon 2 and 3 kGy‐irradiation of Pleurotus eryngii mushrooms during storage …”

“…SEM evaluation ( n = 3; magnification × 1000; accelerating voltage 15 kV) was conducted as described by Akram et al for small pieces of the mushroom cap internal tissue using a Hitachi (Model S‐4300, Tokyo, Japan) microscope.…”

“…A zNose (Electronic Sensor Technology, Newbury Park, CA, USA), equipped with a surface acoustic wave (SAW) sensor and VaporPrint  (Microsense 4.88) software, was used to screen the irradiated mushrooms depending upon their volatile compounds profiles, as described earlier. 15 Principal components analysis (PCA) was used to identify the trend in the numerical data. 16 The European standard EN 1788 17 was used for sample preparation, TL measurements and interpretation of TL identification results.…”

“…Percentage weight loss with respect to the initial weight during storage was evaluated by weekly weighing the mushrooms packs (n = 9). SEM evaluation (n = 3; magnification ×1000; accelerating voltage 15 kV) was conducted as described by Akram et al 15 for small pieces of the mushroom cap internal tissue using a Hitachi (Model S-4300, Tokyo, Japan) microscope.…”
