ABSTRACT

Antinutrients are metabolites that can decrease the bioavailability of nutrients in food, but they can be reduced by certain processing methods. The Obu Manuvu group in Marilog District, Davao City practices indigenous processing of corn. Analyses of the antinutrient content showed a significant decrease in cyanogenic glycoside and tannin. These changes profoundly affected the proximate composition and mineral content of corn. The total carbohydrate, zinc, manganese, and calcium content increased while moisture, crude fat, and crude fiber content decreased after processing. Hence, the indigenous processing of corn by the Obu Manuvu represents a good practice in improving the nutritional profile of corn in terms of greater availability of some nutrients.
