“…A serious problem during post‐harvest handling and storage of peanut and pistachio nuts is mould and insect infestation rendering the products unfit for consumption 10, 11. This in turn, results in serious health hazards and economic losses 12, 13.…”

“…Mycological analyses revealed that the most frequently isolated fungi from nuts were Aspergillus strains 14. In particular, peanuts and pistachio nuts are highly susceptible to damage by the toxigenic A. flavus and A. parasiticus , which can produce the deleterious toxin aflatoxin 11, 15–17. Gürses13 examined 18 peanuts samples, bought from a Turkish market, and found that seven of them were positive for the presence of aflatoxin B 1 with an average concentration of 43 ng g −1 peanut.…”

“…Gürses13 examined 18 peanuts samples, bought from a Turkish market, and found that seven of them were positive for the presence of aflatoxin B 1 with an average concentration of 43 ng g −1 peanut. Furthermore, several insect species belonging to the Coleoptera and Lepidoptera attack peanut and pistachio nuts 11, 12. As a result, post‐harvest preservation strategies are necessary to prevent insect and microbial growth including mycotoxin production in nuts.…”

BACKROUND: The present study evaluated the quality of raw peanuts and pistachio nuts as a function of irradiation dose in order to determine dose levels causing minimal undesirable changes to these products. Physico-chemical (colour, peroxide value, hexanal content, fatty acid composition, volatile compounds) and sensory (colour, texture, odour, taste) properties of raw peanuts and pistachio nuts were determined after irradiation at doses up to 7 kGy. RESULTS:Results showed an eight-and seven-fold increase in peroxide value and a twelve and five-fold increase in hexanal content after irradiation at a dose of 7 kGy for peanuts and pistachio nuts, respectively. An increase was also observed in saturated fatty acids (20.51-28.28% and 15.24-24.87%) with a parallel decrease in unsaturated fatty acids (79.49-71.72% and 84.76-75.13%) for peanuts and pistachio nuts, respectively. Likewise, volatile compounds such as aldehydes, alkanes, ketones and alcohols comprising secondary oxidation products of peanut and pistachio nut lipids increased after irradiation. Pistachio nut colour parameter a * and to a lesser extent parameters, L * and b * decreased after irradiation leading to a slight but noticeable darkening in product colour while colour parameter L * , b * and a * of raw peanut remained unchanged by irradiation up to 7 kGy. CONCLUSION: Based on sensory evaluation, peanuts and pistachio nuts become unacceptable for consumption when irradiated at doses higher than 3 kGy.

A comprehensive review on the status of radiation processing and its future in Iran is presented since 32 years ago up to now to show the development of Iran's irradiation industry. Additionally, annual throughput of treated materials with their types and names are also given and also all of the radiation facilities both in service and under construction as well as the plans and estimations for establishing the new facilities are outlined. Our investigations show that the trend of radiation processing industry in Iran is growing rapidly.
