“…Numerous studies have reported that the softening of fruits induced by irradiation is associated with the decrease in total pectin content (Gunes et al, 2001;Massey and Smock, 1964). Gamma ray irradiation at doses above 400 Gy decreases the firmness of Fuji apples immediately after irradiation (Al-Bachir, 1999; Gunes et al, 2001;Mostafavi et al, 2012). In this study, the firmness of Fuji apples and Niitaka pears was especially reduced at a dose of 800 Gy ( Table 2).…”

“…Nonetheless, no studies were conducted to evaluate the quality and physicochemical parameters of the irradiated fruits. More recently, Mostafavi and others () studied the influence of low‐irradiation doses on apple preservation. The results demonstrated that the germination of spores from Penicillium expansum was completely inhibited with a 0.6‐kGy dose and that doses between 0.3 and 0.6 kGy, which were combined with storage at 1 ºC, could avoid the development of rot for 9 mo without significantly changing the phenolics content, antioxidant activity, firmness, weight loss, and total soluble solids of the treated apples.…”

The mycotoxin issue requires constant vigilance from economic, regulatory, and scientific agents to minimize its toxicological effects on human and animals. The implementation of good practices to avoid fungal growth and mycotoxin production on agricultural commodities is essential to achieve most restrictive safety standards; however, the contribution of novel technologies that may act on postharvesting and poststorage situations may be equally important. Several methodologies, more or less technologically advanced, may be used for this purpose. In this work, we review the role, contribution, and impact of irradiation technology to control the presence of fungi and mycotoxins in food and in feed. The effect of this technology on the viability of mold spores and on the elimination of mycotoxins is reviewed. A critical evaluation of the advantages and disadvantages of irradiation in this context is presented.

“…On the other hand, RT holding after removal from storage caused fluctuations in phenolic content. Increases may be due to ethylene action, known to stimulate phenylalanine ammonia lyase (PAL) activity, a regulatory step in phenolic biosynthesis resulting in accumulation (Mostafavi et al ., ), while the loss of phenolic compounds can be attributed to biotransformation. Napolitano et al .…”

Summary ‘Kathista’ and ‘Lortiko’ are regarded as traditional and highly appreciated apple cultivars in Cyprus, yet their postharvest behaviour and phytochemical content are largely unknown. Such fruits were examined for their qualitative traits, phenolic composition and antioxidant capacity after harvest or short, intermediate or extended cold storage and additional ripening at room temperature (RT), using ‘Gala’ as reference cultivar. Total phenolic content was dependent on cultivar and length of cold storage, while hydroxycinnamic acids were always at higher levels compared to total flavonols for all the examined cultivars. No clear trends regarding the influence of cold storage or RT maintenance on fruit antioxidant properties were evident. Overall, quality attributes and polyphenolic content of the traditional apple cultivars were comparable with ‘Gala’ at harvest; thus, they can be considered a good source of nutraceuticals as summer apple cultivars. However, extended cold storage deteriorates fruit behaviour and antioxidant capacity, particularly in ‘Lortiko’ fruit.
