“…Chemical detoxification is mostly limited to human food, but some compounds (e.g., ammonium, hydrated bentonite, magnetic carbon) can reduce aflatoxin concentration in the final product [36]. Finally, other practices such as crop drying, improved sanitation, controlled processing and storage conditions, significantly contribute to reduce aflatoxin accumulation [22,24,26,30,[37][38][39][40].…”

Aflatoxin contamination of important food and feed crops occurs frequently in warm tropical and subtropical regions. The contamination is caused mainly by Aspergillus flavus and A. parasiticus. Aflatoxin contamination negatively affects health and trade sectors and causes economic losses to agricultural industries. Many pre- and post-harvest technologies can limit aflatoxin contamination but may not always reduce aflatoxin concentrations below tolerance thresholds. However, the use of atoxigenic (non-toxin producing) isolates of A. flavus to competitively displace aflatoxin producers is a practical strategy that effectively limits aflatoxin contamination in crops from field to plate. Biocontrol products formulated with atoxigenic isolates as active ingredients have been registered for use in the US, several African nations, and one such product is in final stages of registration in Italy. Many other nations are seeking to develop biocontrol products to protect their crops. In this review article we present an overview of the biocontrol technology, explain the basis to select atoxigenic isolates as active ingredients, describe how formulations are developed and tested, and describe how a biocontrol product is used commercially. Future perspectives on formulations of aflatoxin biocontrol products, along with other important topics related to the aflatoxin biocontrol technology are also discussed.

“…The results showed that the targeted gene was present in A. carbonarius but absent in A. niger. It has been suggested that AF biosynthesis is a complex pathway involving the pattern of positive-and negative-acting transcriptional regulatory factors affected by environmental and nutritional parameters [35,36]. Thus, AF production does not only depend on the presence of the gene involved in AFs production but also the environmental condition that favors the production of AFs.…”

The growing interest in spicy foods leads to the global demand for spices, particularly dried chili. This study aimed to assay both aflatoxin (AFs) and ochratoxin A (OTA) contamination using an integrative method of morphological identification, molecular detection, and chromatography analysis on dried chili provided from traditional and modern markets in Indonesia. The results showed that total fungal infection ranged from 1-408 × 103 CFU/g. Eighty percent of the chili obtained from both the traditional and the modern markets were infected by Aspergillus spp., in which 50% of the infections were identified as A. parasiticus and A. flavus. A complete set of targeted genes involved in AF production and OTA were detected in two isolates of A. flavus and one isolate of A. carbonarius, respectively. The levels of AFs B1, B2, and OTA in the contaminated dried chilies were in the range of 39.3–139.5 µg/kg, 2.6–33.3 µg/kg, and 23.7–84.6 µg/kg, respectively. In contrast, no AFs G1 and G2 were detected. This study showed that the fungal infection of Indonesian dried chili occurs both in the field and during storage; thus, it is suggested to implement good agricultural and handling processes.

“…Up until now, both aflatoxin detoxification and quality retention in treated products by any single method has not appeared . Although USS can eliminate AFB 1 in peanut, the effect of high temperature on oil quality in oilseeds should be carefully examined.…”
