Project within WP4 (and to a lesser extent WP2 & WP3)

Objectives:

(1) To evaluate alternatives based on cross-modal interactions to reduce the sugar content of dairy products targeted at preadolescents

(2) To determine difference thresholds for sugar in dairy products

(3) To develop dairy products with reduced sugar content and high acceptability from children

(4) To develop guidelines for sugar reduction in dairy products targeted at preadolescents

(5) To investigate the influence of taste sensitivity on preadolescents’ sensory, hedonic and emotional perception of sugar-reduced dairy products

(6) To explore the influence of package design and information on the sensory and hedonic perception of sugar reduced dairy products by preadolescents and their mothers

(7) To compare methodologies for evaluating preadolescents’ sensory and hedonic perception of sugar-reduced products.

Expected results:

The project will provide research-based guidelines for sugar reduction in dairy products targeted at preadolescents, which can encourage the adoption of sugar reduction strategies in the industry. Specific sugar-reduced products would be developed and evaluated. Difference threshold for sugar in three different dairy products (yogurt, chocolate flavoured milk and milk desserts) will be determined with preadolescents. The project will also investigate how package design and information affect sensory and hedonic perception of sugar-reduced products by children and their mothers. 3 papers submitted.

Planned secondments:

(1) Applied secondment in a Norwegian industry (Tine), 3 months, aimed at developing dairy products with reduced sugar content (20-30%). ESR11 will evaluate the influence of sugar reduction on children’s sensory and hedonic perception and shelf life. This project will include close contact to product developers, food technologists, marketing, production and the final consumer via consumer testing.

(2) Academic secondment with NOFIMA, 4 months, to explore multiblock statistical techniques to analyse data of methodologies for evaluating children’s sensory and hedonic perception of sugar-reduced products.

(3) Applied secondment in the public sector with a local policy maker (INDA), 3 months, aimed at studying the influence of packaging on sensory and hedonic perception of sugar-reduced products on preadolescents and their mothers. This project will include close contact to nutritional policy and intervention makers as well as final consumers.
