Spaceward senses: examining retronasal aroma and mouthfeel perception in simulated space-microgravity environments

Abstract

It has been reported that conditions in space missions alter the taste and perception of orthonasal aroma by astronauts. However, there is limited knowledge of the effects of space environments associated with the sensory perception of mouthfeel and retronasal aromas. This research aimed to study alterations in retronasal aromas and mouthfeel under an immersive space-simulated environment with a simulated microgravity seating position. A total of 12 well-trained panelists evaluated the intensity of different samples for retronasal aromas and mouthfeel using a neutral environment and a space-simulated environment. Non-invasive facial biometrics were also analyzed from participants’ videos usi..
