“…For instance, Inan, Pala, and Doymaz () studied the reductions of AFB 1 content in flaked and chopped red peppers were 80% and 93% after exposure to 33 mg/L ozone and 66 mg/L ozone for 60 min, respectively. Tripathi and Mishra () studied the degradation of AFB 1 in chili powder by physical, chemical, and biological methods. Among methods, the degradation rate of AFB 1 was reported to be 83.32% when heated directly at 120℃ for 12 hr.…”

Aflatoxins (AFs) are secondary toxic metabolites. In this study, peanuts were contaminated with 500 µg/L B1, 250 µg/L B2, 250 µg/L G1, and 250 µg/L G2, then exposed to ultraviolet–ozone (UV/O3) with ozone concentrations of 3, 5, and 7 mg/L and exposure times of 10, 20, 30, and 60 min. With increasing exposure time and ozone concentration, the detoxification rates of AFB1, AFB2, AFG1, and AFG2 became more obvious, AFB1 showed the highest degradation rate. After peanuts were treated with 5 mg/L ozone under UV irradiation for 30 min, the degradation rates of AFB1 and AFs (AFs = AFB1 + AFB2 + AFG1 + AFG2) were 79.01% and 67.24%, respectively. Moisture content in peanuts decreased significantly (p < 0.05) with rising ozone concentration. No significances (p > 0.05) were found on the polyphenols, acid value, and peroxide value between UV/O3‐treated and non‐AF‐inoculated peanuts. UV/O3 was a promising method for AFs detoxification in peanuts without affecting nutritional quality. Practical applications The main characteristic of peanut is its high nutritional value, such as vitamins, minerals, and fatty acids. Peanuts are contaminated by AFs easily. The effect of UV/O3 on the AFs, produced by Aspergillus flavus and Aspergillus parasiticus on peanuts, was determined. The results showed that UV/O3 was a promising method in degrading AFs, which was good for long‐term storage of peanuts.

“…However, the application of biological elements such as probiotics is a very efficient method to reduce aflatoxin in foodstuffs (Zoghi et al 2014). It must be mentioned that each strategy has some advantages and disadvantages, and there is not one unique method for all situations (Tripathi and Mishra 2009).…”

Nanocellulose conjugated with retinoic acid: its capability to adsorb aflatoxin B1

et al. 2014

The main aim of this study was to evaluate the adsorption of aflatoxin B1 by nanocellulose conjugated with retinoic acid (NCRA). First, aflatoxin B1 and NCRA were modeled in the Hyperchem software, and then the adsorption of aflatoxin B1 was simulated by the molecular dynamics technique. Second, nanocellulose was synthesized and conjugated with retinoic acid by cross-linker. Third, the adsorption of aflatoxin B1 and NCRA and its release were evaluated at different conditions. Fourth, its adsorption was evaluated in different foodstuffs. Sixth, its toxicity was evaluated on mouse esophageal cells (MECs). Computer-based simulation showed the adsorption of aflatoxin B1 by NCRA. This study showed that the adsorption and release were less affected by temperature and incubation time but highly affected by pH and concentration. Moreover, it was found that NCRA could adsorb aflatoxin B1 in different foodstuffs. Importantly, NCRA had no remarkable toxicity on the MECs.

“…The massive economic effects on the agriculture segment can also be considered because this contamination is able to decrease nutritional significance of food and feedstuff, reduction in meat production, reduced kidney and liver function, immune system suppression and finally created harmfulness to the consumers of dairy/ foodstuffs. So, numerous strategies have been recommended for the AFs detoxification from contaminated food and feedstuff [ 5 – 7 ]. Though, most of the reported methods are having certain drawbacks.…”

Facile, one-pot biosynthesis and characterization of iron, copper and silver nanoparticles using Syzygium cumini leaf extract: As an effective antimicrobial and aflatoxin B1 adsorption agents

In this study, a facile, ecological and economical green method is described for the fabrication of iron (Fe), copper (Cu) and silver (Ag) nanoparticles (NPs) from the extract of Syzygium cumini leaves. The obtained metal NPs were categorized using UV/Vis, SEM, TEM, FTIR and EDX-ray spectroscopy techniques. The Fe-, Cu-and Ag-NPs were crystalline, spherical and size ranged from 40−52, 28−35 and 11−19 nm, respectively. The Ag-NPs showed excellent antimicrobial activities against methicillin-and vancomycin-resistance Staphylococcus aureus bacterial strains and Aspergillus flavus and A. parasiticus fungal species. Furthermore, the aflatoxins (AFs) production was also significantly inhibited when compared with the Fe-and Cu-NPs. In contrast, the adsorption results of NPs with aflatoxin B 1 (AFB 1) were observed as following order Fe->Cu->Ag-NPs. The Langmuir isotherm model well described the equilibrium data by the sorption capacity of Fe-NPs (105.3 ng mg-1), Cu-NPs (88.5 ng mg-1) and Ag-NPs (81.7 ng mg-1). The adsorption was found feasible, endothermic and follow the pseudo-second order kinetic model as revealed by the thermodynamic and kinetic studies. The present findings suggests that the green synthesis of metal NPs is a simple, sustainable, non-toxic, economical and energy-effective as compared to the others conventional approaches. In addition, synthesized metal NPs might be a promising AFs adsorbent for the detoxification of AFB 1 in human and animal food/feed.
