Process Standardization of Functionally Enriched Millet-Based Nutri-Cereal Mix Using D-Optimal Design Approach for Enhancing Food and Nutritional Security

Abstract

Millets are currently employed in a variety of ways, including direct consumption and usage in the manufacture of certain cuisines or snacks. The present investigation was aimed at optimizing functionally enriched millet-based nutri-cereal mix comprising chicken and vegetable for a nutrition-deficient population. A total of 16 experiments were carried out by using optimal (custom) design model of mixture design with 60% major ingredients, including malted sorghum flour (20−30%), malted green gram flour (15−25%), and boiled chicken powder (5−15%). To make 100% of the total nutri-cereal mixture, other ingredients such as malted pearl millet (10%), finger millet flour (10%), beetroot powder (2.5%), pumpkin powder (7.5%), skimmed milk powder (9.5%), and stevia powder (0.5%) were added. Numerical optimization was done using Design Expert software, version 13. The optimized ratio was 30% malted sorghum flour, 15% malted green gram flour, and 15% chicken powder. The predicted values of responses 5.
