(P20-041-20) A Methodology to Assess a Relevant Combination of Parameters for a Satisfying Snacking in a Reasonable Portion Size

Objectives: Portion size, and especially oversizing lead to overconsumption without compensation at next meals. This has been well demonstrated in children and in adults (Hetherington et al. 2018). Downsizing showed interesting reduction in energy intake, especially in lab conditions (Poelman et al. 2015). One proposal from industry is to offer single-served packs, especially the ones more dedicated to snacking occasions. One of the big challenges is to provide high enough satisfaction to the consumer with a defined fixed portion. The objective of our methodology is to define the right portion size which provides enough satisfaction for most of the consumers, in line with the recommended daily allowance.

Methods: We developed a methodology to determine the right portion of food based on satisfaction. In cross-over designs, at least 100 consumers were asked to eat as much as they want of the proposed snack until they feel fully satisfied for a snack at this time of the day. We then evaluated the amount of snack consumed (g and kcal), their appetite sensations, the measured expectation based on pictures, the feelings after consumption (appropriateness, guiltiness, fullness) and the sensory properties of foods, in lab condition.

Results: Based on the results of 4 studies, the data showed that the right portion is not only about hunger. It is also a compromise including overall satisfaction driven by a balance between appropriateness, healthiness, less guiltiness, liking and other sensory dimensions. Cultural differences were observed with a higher preferred portion for the same product for UK compared to France. Optimal portion size is generally higher for men than women. The bigger the volume, the smaller the portion consumed. For several products, the portion inducing the higher level of satisfaction is different from the serving size mentioned on the packs.

Conclusions: In conclusion, portion control may help in snacking occasions if it is related to consumers’ satisfaction to limit energy intake during these eating occasions. This may be a complementary approach which could be part of mindful eating and limit the quantity of energy dense foods eaten each day.
