Development of a nutrient-fortified cereal-legume bar: A novel approach to combating micronutrient deficiencies in developing countries

Abstract

The development of nutrient-dense food products is a critical strategy to combat micronutrient deficiencies, particularly in low-income populations. This study focuses on the formulation and evaluation of a novel cereal-legume bar, fortified with essential micronutrients, including iron (10 mg), calcium (200 mg), zinc (5 mg), magnesium (50 mg), and vitamins A (200 IU) and C (25 mg), aimed at addressing malnutrition. The fortified bar was evaluated for sensory attributes, physico-chemical properties, microbiological safety, and nutritional content. Results showed that the fortified bar had a significant increase in nutrient content compared to the control bar, with iron, calcium, and zinc levels exceeding recommended daily intakes by 30%, 25%, and 40%, respectively. Sensory evaluation using a 9-point hedonic scale revealed an overall acceptability score of 8.2±0.5 for the fortified bar, significantly higher (p
