- reducing the risk of pellagra by increasing niacin (Vitamin B3):
- increasing calcium ingestion because the maize grains absorb it from the lime during the boiling process;
- increasing fibre intake due to high content of resistant starch in food products; and,
- reducing mycotoxins in maize.
Mexico’s Maize Nixtamalization Project in Kenya
March 17, 2019
Challenge
Maize is a basic food product in Kenya. Its per capita consumption is high (103 kg/year) and it constitutes 31 per cent of Kenyans’ caloric intake. In Kenya, maize is used in only 10 food products, as opposed to Mexico, where it is used in more than 600. Its few uses in Kenya restrict both per capita consumption and demand for farmers’ production, while limited processing restricts the maize value chain and inhibits opportunities for industrialization in Kenya. Moreover, the devastating consequences of aflatoxin contamination are well- known in the agricultural sector and are also visible in the health and nutrition status of the affected population.
Towards a Solution
Mexico, as the cradle of corn, has vast experience in the use of maize and has developed diverse food products that use corn, principally derived from a process known as nixtamalization that involves cooking the grain in a lime solution and soaking it for a few hours to ensure the removal of any remaining organic components and excess alkali. This was seen as a solution to address Kenya’s challenge.
The process offers numerous nutritional benefits, such as:
