Are There Organoleptic Differences between Micronutrients Fortified Pure Natural Milk and Fortified Constituted Milk?

Introduction: The school age (6-11) is an important stage and a nutritionally vulnerable age group. Sensory acceptance for fortified micronutrients milk is required to expand the milk program to improve nutrition for school children on a nationwide scale. Objective: Assessing organoleptic acceptance of fortified micronutrients milk in primary school children in PhuBinh district, Thai Nguyen province, and a rural district in the Northern mountain of Vietnam. Method: Fortified micronutrients milk formula was developed base on the World Health Organization (WHO) recommendations. Children were chosen from the subjects that participated in the effectiveness study of fortified micronutrients 100% natural milk and fortified micronutrients constituted milk to involve in the sensory acceptance research using the hedonic scale (9 points). Results: Dietary intake in the research met the recommended dietary allowances for varying age groups of energy from 6.6% to 10.7%, of protein from 10.8% to 21.6%, of vitamin A from 19% to 25.3%, of vitamin D approximately 12.7%, of water-soluble vitamins from 13% to 36%, of iron from 15% to 30.9%, zinc from 16.7% to 30% and other minerals from 10.1% to 36%. Chi-square test gave a p-value<0.0001, showing a significant difference in the result of organoleptic acceptance ranging from terrible to great. The number of acceptance was much higher than that of unacceptance. Fisher extract test gave a p-value>0.05, showing no significant difference between the group of fortified micronutrients 100% pure natural milk and that of the fortified constituted milk for the score of larger than 5 among all organoleptic qualities including color, taste, smell, flavorful and overall acceptance. Conclusion: fortified micronutrients 100% pure natural milk and that of constituted milk can be used for school children in Vietnam under the standpoint of sensory acceptance.
