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.

“…For example, Yang et al assessed the feasibility of mid-infrared (MIR) technique to screen AFB1- and AFT-positive peanut oil. Different models could both reach 100% in calibration and validation [ 26 ]. However, the AFT-contaminated samples used in their study were produced using the general AFTs induction methods.…”

This study proposes a label-free rapid detection method for aflatoxin B1 (AFB1) in pressing peanut oil based on Raman spectroscopy technology combined with appropriate chemometric methods. A DXR laser Raman spectrometer was used to acquire the Raman spectra of the pressed peanut oil samples, and the obtained spectra were preprocessed by wavelet transform (WT) combined with adaptive iteratively reweighted penalized least squares (airPLS). The competitive adaptive reweighted sampling (CARS) method was used to optimize the characteristic bands of the Raman spectra pretreated by the WT + airPLS, and a partial least squares (PLS) detection model for the AFB1 content was established based on the features optimized. The results obtained showed that the root mean square error of prediction (RMSEP) and determination coefficient of prediction (RP2) of the optimal CARS-PLS model in the prediction set were 22.6 µg/kg and 0.99, respectively. The results demonstrate that the Raman spectroscopy combined with appropriate chemometrics can be used to quickly detect the safety of edible oil with high precision. The overall results can provide a technical basis and method reference for the design and development of the portable Raman spectroscopy system for the quality and safety detection of edible oil storage, and also provide a green tool for fast on-site analysis for regulatory authorities of edible oil and production enterprises of edible oil.

“…Using near infrared (NIR) technology to detect mold in edible oil has also been a research hotspot in recent years. Researchers have promoted the further application and development of IR technology by establishing qualitative and quantitative analysis models for AFB 1 pollution in edible oil [ 151 , 152 , 153 ].…”

Recent Progress on Techniques in the Detection of Aflatoxin B1 in Edible Oil: A Mini Review

Contamination of agricultural products and foods by aflatoxin B1 (AFB1) is becoming a serious global problem, and the presence of AFB1 in edible oil is frequent and has become inevitable, especially in underdeveloped countries and regions. As AFB1 results from a possible degradation of aflatoxins and the interaction of the resulting toxic compound with food components, it could cause chronic disease or severe cancers, increasing morbidity and mortality. Therefore, rapid and reliable detection methods are essential for checking AFB1 occurrence in foodstuffs to ensure food safety. Recently, new biosensor technologies have become a research hotspot due to their characteristics of speed and accuracy. This review describes various technologies such as chromatographic and spectroscopic techniques, ELISA techniques, and biosensing techniques, along with their advantages and weaknesses, for AFB1 control in edible oil and provides new insight into AFB1 detection for future work. Although compared with other technologies, biosensor technology involves the cross integration of multiple technologies, such as spectral technology and new nano materials, and has great potential, some challenges regarding their stability, cost, etc., need further studies.
