"Complementary to ingredients that focus on the postingestive and postabsorptive stage of the satiety cascade, retronasal aroma release, operating during food ingestion, has a consumer benefit that is immediately noticeable," they added. (via Stephen Daniells,
"Among the proof-of-principle studies that were performed, the prolongation of the duration of retronasal aroma release, the addition of specific ingredient-related aroma cues, the engineering of more complex aroma compositions, and the adaptation of bite size or duration of oral processing may prove to be valuable aroma concepts for the development of foods containing triggers that induce or increase the feeling of satiation.
A recent article in the Journal of Agricultural and Food Chemistry, a publication of the American Chemical Society, described the phenomenon in scientific prose like this: "Although the extent of retronasal aroma released appears to be subject-specific, food product properties can be tailored in such a way that these can lead to a higher quality and/or quantity of retronasal aroma stimulation.
