Recent advances in aflatoxin B1 detection based on nanotechnology and nanomaterials-a review. Aflatoxins can be absorbed by microorganisms directly either by concatenating to their cell wall contents through effectual internalization or congregation (Motawe et al. (2014). 2017). https://doi.org/10.1016/j.ijfoodmicro.2016.08.019. The study findings reveal that, in general, aflatoxin contamination was a bigger problem in groundnut than in maize samples from similar sources in Malawi for the reported period. Aflatoxin M1 contamination in dairy products. Here they have used HPLC, which is Electrochemical enzyme-linked oligonucleotide array for aflatoxin B1 detection. Qureshi, H., Hamid, S. S., Ali, S. S., Anwar, J., Siddiqui, A. Journal of Biosciences, 40(5), 943954. (2015). There are mainly six different types of aflatoxins-Aflatoxins-B1(AFB1), Aflatoxins-B2(AFB2), Aflatoxin G1(AFG1), Aflatoxins G2 (AFG2), Aflatoxin M1 (AFM1), and Aflatoxin M2 (AFM2) (Quadri et al. associated with deleterious health effects. 2010). Vitamins, amino acids, and metal ions also promote aflatoxin production in combination. Apart from the above-mentioned factors, A. flavus is the main species that is mainly responsible for aflatoxin production and crop contamination because it is the most copious molds found in soil and possesses the saprobe character that enables it to grow on many organic nutrient substrates including compost piles, plant debris, cotton, dead insects, stored grains, field crops, animal corpses and animal fodder (Kakde 2012).

Issue Section: Food Chemical Contaminants Fungal bioaerosols: Global diversity, distribution, and its impact on human beings and crops. Weeds mostly grow as a competitor and cause plant stress which is associated with aflatoxin production.

Several approaches have been manifested to reduce the aflatoxin contamination in crops which include various physical, chemical, and biological methods. Food Control, 45, 2935. Aflatoxin B1 and B2 are produced by A. flavus, while Aflatoxin G1 and G2 are synthesized by A. parasiticus and largely contaminate a wide range of food commodities including cereals (maize, sorghum, pearl millet, rice, and wheat), oilseeds (peanut, soybean, sunflower, and cotton), spices (chilies, black pepper, turmeric, coriander, and ginger), nuts (almond, Brazil nut, pistachio, walnut, and coconut), yam and various milk products (Rajarajan et al.

Matumba, L., Sulyok, M., Njoroge, S. M., Ediage, E. N., Van Poucke, C., De Saeger, S., & Krska, R. (2015). Aflatoxins are a naturally occurring carcinogenic byproduct of common fungi on grains and other crops, particularly maize and groundnuts. The recent development of aflatoxin contamination biocontrol in agricultural products. The persistent occurrence of aflatoxins in food and feed remains a problem for producers of commodities subject to colonization with toxigenic molds. Because of their toxic nature, these food contaminants have acknowledged considerable attention in recent years. Among gasses, ozone was found to be most effective in maximizing the aflatoxin degradation on legumes and cereals by an electrophilic attack on carbon bonds of furan ring (Jalili 2016).

In particular, aflatoxin B1 has been identified as a Class I carcinogen to humans by the International Agency for Research on Cancer (IARC). Lipids also play an important role in aflatoxin production. Mycotoxin Research, 32(4), 179205. Nitrogen in the form of nitrite and nitrate also increases the aflatoxin production level by A. flavus in various ways (Wang, Han, et al. Hence, those methods that provide instant results are proved to be useful when considering a large sample. https://doi.org/10.1021/acs.analchem.7b02794.

The four major aflatoxins like AFB1, AFB2, AFG1, and AFG2 are commonly found in a wide range of food commodities, AFB1 and AFB.2 are produced by A. flavus while AFG1 and AFG2 are produced by A. parasiticus. Because current screening methods for these toxins are lengthy, destructive, and costly, there is a continuous search for a more . highly sensitive and robust aflatoxin analysis can be assured. Chu, X., Wang, W., Yoon, S. C., Ni, X., & Heitschmidt, G. W. (2017). While handling pure aflatoxin reference material, extreme precautions are to be taken as they are electrostatic. In recent years, post-column bromination reactions have replaced older PLoS One, 12(6), e0178810. Various methods were introduced to detect aflatoxins, such as ELISA and HPLC using mass detection and several other methods.
