Lai, X., Liu, R., Ruan, C., Zhang, H., & Liu, C. (2015). Large doses of aflatoxins lead to direct death and damage, while small longstanding doses lead to immunologic or nutritional effects, but both types of doses lead to liver cancer due to the accumulation of aflatoxin (Marroqun-Cardona et al. Aflatoxin occurrence in nuts and commercial nutty products in Malaysia. (2015). 2014). A., & Khan, N. A. Tropical Biology and Conservation Management, 7, 6084. However, due to the bad image quality of VNIR, some recent studies focused on the combined use of the HSI technique with chemometric data analysis that resulted in better identification of AFB1 on the surface of maize kernels (Kimuli et al. The amount of aflatoxin production mainly depends on types of fungi; insects wound in the plant cause stress and provide the site for aflatoxigenic fungi for contamination (Kinyungu 2019). 2009). Shu, X., Wang, Y., Zhou, Q., Li, M., Hu, H., Ma, Y., & Wu, L. (2018).

TRFICA and PD-IPCR provides a detection limit of 0.05 ng/mL and 0.0.03 ng/mL respectively for aflatoxins. including Aspergillus, Penicillium, Fusarium, and Alternaria but Aspergillus flavus and Aspergillus parasiticus are known to produce the most toxigenic strains of aflatoxins. Mycotoxin Research, 31(1), 5762. Consumption of foods and feeds contaminated by aflatoxins are hazardous to human and animal health, hence the detection and quantification of aflatoxins in foods and feeds is a priority from the viewpoint of food safety. 2016). This study has implications for planning an integrated approach for management of aflatoxin contamination in food in sub-Saharan Africa. Some food additives are also used for the inhibition of fungal growth and aflatoxin production in combination with some physical factors like temperature and moisture. Embaby, E., & Hassan, M. K.
