Longer exposure to the aroma leads to an increased feeling of fullness

The feeling of fullness increases with the aroma released during food consumption. Furthermore, the complexity of aromas and the length of time food is chewed influence appetite regulation. Groundbreaking research on the role of aromas in satisfying hunger was presented by Rianne Ruijschop from NIZO Food Research in the Netherlands. The obesity epidemic is presenting scientists with new challenges. Rianne Ruijschop was the first in the world to demonstrate that aromas that reach the nose during eating affect satiety and can, consequently, interrupt a meal. Aromas released during chewing can effectively reduce hunger, preventing overeating. How did the researcher reach her conclusions? Ruijschop observed a group of people chewing their food. They directed the odor from their mouths toward the back of their noses. This activated the area of ​​the brain responsible for the feeling of fullness. Hunger was effectively suppressed. What increased the feeling of satiety? By isolating aroma profile from other stimuli, Ruijschop investigated the importance of smell in satiety using a specially adapted olfactometer. She found that the complexity of the aroma composition, the time it takes for food to process in the mouth, and the duration of the aroma's lingering effect all enhance the feeling of being full. Do solid and liquid foods fill you up similarly? Liquid foods release aromas for a much shorter time than solid foods, making them less filling. Solid foods, which require chewing and swallowing, release aromas that help satisfy hunger. For example, modifying the properties of a beverage to release as many aromas as solid foods will increase the feeling of fullness. How do complex fragrances work? Multi-component aromas are perceived as more complex despite similar aroma quality, intensity, and pleasant character. Ruijschop demonstrated that multi-component strawberry aroma, compared to single-component strawberry aroma, can increase satiety. Complex aromas suggest meal variety and larger portion sizes. How will this discovery help prevent obesity? The goal is to enhance the flavor and aroma of foods in a way that induces a feeling of fullness. This will counteract the effects of overeating. Consider adding flavor enhancers or ingredients that encourage chewing.
