“…Preharvest practices high in repeated misuse of chemical fertilizer and farmer‐saved seeds, poor harvesting conditions, poor drying conditions, and poor storage structures result in fungi growth and mycotoxin production (Lehmane et al., 2022 ; Tang et al., 2019 ). Hence, ZEA concentrations in food are underpinned by three powerful factors—Preharvest factors identified as fertilization levels, fungicides use, and harvest practices; postharvest factors such as drying techniques, storage conditions; and food processing factors including sorting and fermentation.…”

The fungal genus Fusarium contains many important plant pathogens as well as endophytes of wild and crop plants. Globally, Fusarium toxins in food crops are considered one of the greatest food safety concerns. Their occurrence has become more pronounced in Africa in recent times. Among the major Fusarium mycotoxins with food and feed safety concerns, zearalenone is frequently detected in finished feeds and cereals in Africa. However, the impact of indigenous agricultural practices (pre‐ and postharvest factors) and food processing techniques on the prevalence rate of Fusarium species and zearalenone occurrence in food and feed have not been collated and documented systematically. This review studies and analyzes recent reports on zearalenone contamination in maize and other cereal products from Africa, including its fungi producers, agronomic and climate variables impacting their occurrences, preventive measures, removal/decontamination methods, and legislations regulating their limits. Reports from relevant studies demonstrated a high prevalence of F. verticillioides and F. graminearum as Africa's main producers of zearalenone. Elevated CO2 concentration and high precipitation may carry along an increased risk of zearalenone contamination in maize. African indigenous processing methods may contribute to reduced ZEA levels in agricultural products and foods. Most African countries do not know their zearalenone status in the food supply chain and they have limited regulations that control its occurrence.

“…One of the major challenges in maize storage is the infestation by pests, such as weevils (Sitophilus zeamais), which can cause substantial grain damage and weight loss [10]. Additionally, improper storage conditions can lead to the growth of fungi, resulting in the production of mycotoxins that pose serious health risks to both humans and animals [11].…”

Complex Evaluation of Storage Impact on Maize (Zea mays L.) Quality Using Chromatographic Methods

et al. 2023

Maize (Zea mays L.), a food crop cultivated worldwide, is renowned for its nutritional and economic value. However, its quality can be significantly affected by various storage conditions, leading to changes in its nutritional composition and potential contamination with harmful substances, such as aflatoxins. This article presents a comprehensive evaluation of the impact of storage on maize quality, focusing on several key parameters analyzed using liquid chromatographic methods and FT-NIR spectrometry. The research reveals a decline in the concentrations of key nutrients over the storage period. Specifically, there was a 19.7% loss in vitamin B1, a 12.43% loss in vitamin B3, a 16.96% loss in α-tocopherol, a 13.61% loss in total tocopherols, and an 8.02% loss in β-carotene. Aflatoxins were mostly undetectable, with one exception in January that remained below the maximum permitted level of 0.3 µg/kg. The parameters include the concentration of vitamins B1, B3, α-tocopherol, total tocopherols, β-carotene, aflatoxin B1, total aflatoxins, carbohydrate content, and protein content. Aflatoxins were mostly undetectable, with one exception in January—0.3 µg/kg—that remained below the maximum permitted level. The study underscores the importance of cooling maize immediately after drying to minimize nutrient loss, providing valuable insights for optimizing storage processes to maintain the nutritional quality of maize.
