Everyone is aware that there is a scent that could be appetizing, and also the smell that makes us nauseous and lost appetite. But you know, there are molecules in the aroma of foods that can trigger certain parts of the brain to feel full.
The scent which helps relieve that hunger is a fragrance that rises from the mouth into the cavity behind the nose when we chew, so the discovery team Ruijschop Rianne, an expert in food technology from NIZO Food Research Centre, in Ede, Netherlands.
"This result is unexpected," said Ruijschop. "We were quite surprised and enthusiastic about the results of these findings."
Variations findings
Aroma, flavor, and texture can make some people feel full. Some of the facts found, among others:
* Solid foods to be chewed and swallowed, and thus produce the scent that remains long, proved to be more satiating than liquid foods.
* The smell associated with fat, carbohydrates, or proteins, can increase satiety, perhaps because this smells indicate that foods containing high energy consumption.
* The smell is more complicated, with many components, more filling than a monotone. Complex aroma can make our brains feel that we have consumed many foods, and concluded that the portions are certainly large.
* The size of food samples was also influential, since the sample in small pieces to prolong the onset of the effects of scents.
In the experiment, the researchers can vary the level of satiety arising from a variety of foods. For example, create a strong-flavored beverages such as solid foods may increase satiety.
Satiety
These findings could help researchers create a new generation with the scent of a glut of food, so they can combat obesity and overeating tendencies. Scientists can add a capsule that could increase or prolong the taste that remains in the mouth or adding a particular aroma. In addition to the effects of scent, they also might be able to create materials that can be chewed, or out on pieces of food so that people chew more; as more chewing makes us think more of food portions. Complex aromas that can be added, and also the smell that makes us think that foods rich in energy consumed.
In recent findings, Ruijschop said that by controlling the scent they can reduce the amount of food consumed approximately 10 percent. Now the scientists are doing research to see what long term effects on people who have for months to consume food that flavor has been altered.
Although the smell could help reduce obesity, but, "this alone is not a solution," said Ruijschop. "The point is to change the pattern of life."
Ruijschop and its partners have outlined their findings in the 11 November issue of the journal Agricultural and Food Chemistry. -kompascom
