Effects of different purities of calcium hydroxide on nutrient composition and reduction of aflatoxin and fumonisin in maize and maize-based food

Mycotoxin contamination in maize remains a significant issue in Kenya. Nixtamalization, a chemical detoxification method, has been employed to reduce aflatoxin and fumonisin levels in maize. Despite its long-standing use, the uptake of nixtamalization in Kenya is limited due to the lack of high-quality Ca(OH)?. The available lime in the market has a purity of only 85%. Therefore, this study aimed to assess the...
