In the first series of experiments, 348 students assessed their appetite before and after exposure to one of three essential oil aromas of Sichuan pepper. After exposure to all three aromas, participants reported increased hunger and decreased feelings of fullness.
In the second series, 78 men inhaled one of the three aromas before breakfast. After exposure to the aromas, they consumed 15-19% more than after the control sample.
The third series of experiments demonstrated that the aroma could act even without prior food experience. Mice exposed to the essential oil vapors increased their food intake.
Researchers suggest that a familiar aroma may remind individuals of the taste and pleasure of food, enhancing the desire to eat. However, the effect may vary among women and older individuals, necessitating further research.
