Effect of body mass index in acceptability of regular and light drinking yoghurt

Abstract:

Calorie reduced products represent an important market for many food companies. For a given type of calorie reduced product, the consumer has in many cases, several brands to choose from. Such a strong competition require an optimization of the sensory attributes of the product. In addition, consumer expectations for" light" products are as high as for the regular counterparts." Light" products are targeted to both normal and overweight consumers. Thus it is important to detect if body weight status has an effect in food sensory acceptability. The objective of this work was to study if body mass index had an effect on the sensory acceptability of three commercial strawberry drinking yoghurts and their calorie reduce versions. A total of 350 adult consumers evaluated the acceptability of the products and each consumer had its body mass index measured. Based on the BMI, consumers were classified in two groups: normal (BMI< 25), overweight/obese (BMI> 25). Analysis of Variance was used to evaluate the effect of BMI and yoghurt type on the acceptability of the products. For both groups of consumers, the" light" products had lower acceptability than the regular ones. For the normal consumer group, the degree of sweetness and tartness was less acceptable in the light products than in the regular products, while the overweight/obese group did not reported a significant difference. The selection of the best products varied between the two groups. These results suggests that BMI has an effect on the sensory evaluation of food products
