What is satiating? Consumer perceptions of satiating foods and expected satiety of protein-based meals

Sammendrag

Designing food items with high satiating capacity is an area of increasing interest. It would be desirable for consumers to be able to make informed choices about individual products based on understanding the energy balance and the meaning of satiety. In the present work, the perceptions that consumers have of the word “satiating” and of different protein-based dishes were investigated in two populations (100 subjects related to the field of food science and technology and 100 unrelated to it). The Word Association (WA) technique was used, asking the consumers for the first four words that came into their mind when they thought of “satiating food”. This was followed by a Free Listing (FL) exercise that asked themto list four satiating food items. They also completed aNutritional Knowledge Questionnaire. To evaluate the consumers' perception of the expected satiating capacity of different protein-based meals, they were shown eight photographs of equicaloric dishes composed of one piece of protein (beef, pork, chicken or fish) and one of two different side vegetables (salad or boiled potatoes). The expected satiety scores ranked fish last among the protein foods and potatoes last among the side vegetables. The results indicated that “satiating” food was related more with the immediate sensation of “stomach full” than with the cessation of hunger. This was reinforced by the mention of negative sensations of discomfort after a copious meal. Hearty dishes and meat were the meals most associated with satiating food items.
