研究表明，通过对所吃食物的气味的愉悦度与其他食物的愉悦度的变化进行评级来衡量的嗅觉感官特异性饱腹感，可以通过吃到饱腹感而产生。研究还表明，咀嚼一种食物的时间大约与通常在一顿饭中吃的食物的时间一样长，就可以产生嗅觉和味觉上特定的饱腹感。研究进一步表明，部分嗅觉特异性的饱腹感可以通过闻食物产生，时间大约和食物在嘴里的时间一样长。这些对食物愉悦感的感官特异性变化似乎并没有反映出食物强度的变化，食物强度的变化很小，与愉悦感的变化没有高度相关。结果表明，至少部分嗅觉，以及味觉，感官特异性饱腹感不需要食物进入胃肠道系统，也不依赖于卡路里的摄入。研究人员考虑了对食物摄入控制的影响，以及大脑计算特定感觉饱腹感的方式。(C) 1997爱思唯尔科学有限公司
It is shown that olfactory sensory-specific satiety, measured by ratings of the pleasantness of the odour of a food eaten relative to the change in pleasantness of other foods, can be produced by eating a food to satiety. It is also shown that olfactory and taste sensory-specific satiety can be produced by chewing samples of a food for approximately as long as the food would normally be eaten in a meal. It is further shown that partial olfactory sensory-specific satiety can be produced by smelling the food for approximately as long as it would be in the mouth during a meal. These sensory-specific changes in the pleasantness of a food do not appear to reflect changes in the intensity of the foods, which were small and not highly correlated with the changes in pleasantness. The results show that at least partial olfactory, as well as taste, sensory-specific satiety does not require food to enter the gastrointestinal system, and does not depend on the ingestion of calories. The implications for the control of food intake, and the way in which the brain computes sensory-specific satiety, are considered. (C) 1997 Elsevier Science Inc.
