Effects of electron-beam and gamma irradiation treatments on the microbial populations, respiratory activity and sensory characteristics of Tuber melanosporum truffles packaged under modified atmospheres

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

“…Irradiation treatment can affect water loss during storage of fresh produce by altering different physiological processes, particularly respiration rate . This effect was evident in the 1 kGy‐irradiated mushrooms, which maintained the most weight during storage (Fig.…”

“…Different physiological changes and microbial action are major concerns that might be responsible for color deterioration during storage . Irradiation can address these problems, as was evident in the 1 kGy‐irradiated mushrooms. 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 .…”

“…25 Dark-colored patches on the cap surface, particularly in the 3 kGy-irradiated mushrooms, also supported this view. Rivera et al 27 and Jang et al 4 also reported negative quality attributes in mushrooms at irradiation doses >1 kGy.…”

Gamma irradiation can control the number of psychotrophic bacteria in Agaricus bisporus during storage

“…It is known that the type of mushroom and irradiation dose applied directly influence the results of increasing the mushrooms' shelf life. About this, Rivera et al (2011) evaluated the effect of gamma irradiation on the microbial population of Tuber melanosporum; during 35 days of storage at 4°C, they found that the dose of 1500 Gy did not increase the useful life of mushrooms and maintenance of the quality of truffles. Moreover, Jiang et al (2010), evaluating the effect of integrated application of gamma irradiation (1000, 1500 and 2000 Gy) and modified atmosphere on the microbiological properties of shiitake mushroom (Lentinula edodes), found that the dose of 1000 Gy was the most efficient in maintaining the firmness level of mushrooms.…”

Application of Modified Atmosphere Packaging on Quality of Selected Vegetables: A Review

“…santamariae survived and were the dominant microbial populations. The use of high irradiation dosages did not favor texture characteristics thereby limiting the shelf life to 28 days (Rivera et al 2011b ).…”
