Measuring Acceptance of Milk and Milk Substitutes Among Younger and Older Children

Appropriate nutrient-dense foods and beverages are crucial for children for proper growth and development and to develop healthful lifelong habits. This study investigated children's (ages 8 to 16 y old) perception of sensory intensity, attribute liking and overall liking of unflavored and chocolate lactose-free cow's milk and soy beverages. Products were not identified as to whether they were soy or milk. Children showed greater acceptance of lactose-free cow's milk compared to milk substitute beverages, within flavor category. No differences in acceptance emerged by ethnic group (Caucasian, African American, Hispanic), but a large difference emerged by age group. All product acceptance differences perceived by older children reoccurred among the younger children and in the same direction, but the older children used a larger range of numbers, especially at the lower end, rather than at the higher end of acceptance. The effect of age is not a simple scaling bias but may suggest a reduced criticism by younger respondents of less-acceptable products.
