“…In the dry condition, both mycotoxins were stable to irradiation at 50 kGy. Using electron bean irradiation, Stepanik and others () also demonstrated a dose‐dependent reduction of DON contents in wet distiller grains used as feed supplement. Reductions reached 47.5% to 75.5% at the highest doses (about 50 kGy).…”

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.

“…The hydroxyl radicals remove hydrogen atoms from sugar and from the 4 bases of DNA strands (Lado and Yousef ). The other free radicals will also attack and break down organic molecules (Stepanik and others ). Potentially lethal DNA lesions are randomly scattered throughout the cell population during ionizing.…”

“…At the irradiation dose of 50 kGy, the degradation rates of ZEN and OTA in corn kernel were 71.1% and 67.9%, respectively. Stepanik et al [34] found that the reduction of deoxynivalenol level in wet distillery grain, distiller’s solubles, and stillage exhibits a dose-dependent increase. Aziz et al [35] reported that gamma irradiation is effective against AFB 1 , ZEN, and OTA in food and agricultural products; at 20 kGy, AFB 1 and ZEN are completely disrupted and OTA content in samples is reduced by 72%–76%.…”

Zearalenone (ZEN) and ochratoxin A (OTA) are secondary toxic metabolites widely present in grains and grain products. In this study, the effects of electron beam irradiation (EBI) on ZEN and OTA in corn and the quality of irradiated corn were investigated. Results indicated that EBI significantly affected ZEN and OTA. The degradation rates of ZEN and OTA at 10 kGy in solution were 65.6% and 75.2%, respectively. The initial amounts significantly affected the degradation rate. ZEN and OTA in corn were decreased by the irradiation dose, and their degradation rates at 50 kGy were 71.1% and 67.9%, respectively. ZEN and OTA were more easily degraded in corn kernel than in corn flour. Moisture content (MC) played a vital role in ZEN and OTA degradation. High MC was attributed to high ZEN and OTA degradation. The quality of irradiated corn was evaluated on the basis of irradiation dose. L* value changed, but this change was not significant (p > 0.05). By contrast, a* and b* decreased significantly (p < 0.05) with irradiation dose. The fatty acid value increased significantly. The pasting properties, including peak, trough, breakdown, and final and setback viscosities, were also reduced significantly (p < 0.05) by irradiation. Our study verified that EBI could effectively degrade ZEN and OTA in corn. Irradiation could also affect corn quality.

“…The toxicity of transformation products had been lowered after heat treatment, but there was no phenomenon about the degradation of T-2 toxin [8]. Similarly, the obvious reduction of T-2 toxin amount in grains did not appear after treatment of γ-ray and electron beam [11]. The toxicity of T-2 toxin could be lowered by treatment of NaClO solution in NaOH, but it could result in the Chloride residue [12,13].…”

The degradation of T-2 toxin in aqueous solution and patulin in apple juice at different conditions by glow discharge plasma (GDP) was investigated. High performance liquid chromatograph (HLPC) was used to analyze the toxins concentration which was changed by treatment time. The results showed that GDP treatment could rapidly and effectively degrade T-2 toxin in aqueous solution and patulin in apple juice. The higher the initial toxin concentrations, the higher treatment efficiency could be achieved within the same time. The degradation rates of T-2 toxin at any different initial concentration were all up to 30% after 8 min, whilst no T-2 toxin was detected after 40 min. The toxin removal rate was faster at a relatively higher acidity and alkalinity levels. The Fe 2+ and H 2 O 2 exhibited strong catalysis ability to the degradation reactions. The values of pH in the degraded solution were decreased rapidly due to the formation of carboxylic acids. Afterwards, the values were increased as carboxylic acids were decomposed into CO 2 and H 2 O. The dynamics equation curve is most appropriate and confirms that the degradation reaction of T-2 toxin by GDP belonged to the first order kinetics reaction, which could be expressed as ln (C 0 /C t )=kt. Quality evaluation of the apple juice indicated that GDP treatment within 10 min had little effects on quality of apple juice.
