TASTE THRESHOLDS TO BITTER COMPOUNDS DURING A SUBMARINE PATROL

Abstract

Polaris submarines make two month patrols and are submerged without external ventilation during the entire time. The atmosphere is controlled to maintain habitability using CO, CO2 and H2 removers, as well as, O2 generators. The ambient CO2 is elevated during the entire patrol to an average level of 1. 0%. In general, the atmospheric trace components of this closed environment are expected to differ from those found under normal environmental conditions. Past study has indicated a decrease in the taste threshold for the sour modality aboard submarines. This study was undertaken to test the effect of this atmosphere on the bitter modality threshold. Taste thresholds for quinine (bitter) were determined during the refit period while in port and used as a baseline. Three subsequent taste tests were accomplished during the patrol at about two week intervals. A borderline statistically significant decrease in taste threshold (more sensitive) for quinine was noted. A consistently higher threshold was noted in smokers than in non-smokers.
