Abstract
13 rats recognized the difference between distilled water and sucrose soln. in avg. concs. of 0.5% (or 0.0146 M). 45 young adult humans first recognized the difference between distilled water and sucrose soln. in avg. concs. of 0.17% and first recognized a sweet taste in avg. concs. of 0.41%. 19 adults from the laboratory staff and clinic patients showed similar results. The sugar taste threshold of 58 children averaged 0.68% and of 52 elderly individuals, 1.23%. Since the sucrose taste threshold of the rats (0.5%) agreed more closely with the sweet taste threshold of humans (0.4-0.7%) than with the taste difference threshold (0.17%), the rats apparently did not start to drink more sucrose and less water until they recognized a definitely sweet taste. Rats and humans have nearly the same sucrose taste thresholds.This publication has 1 reference indexed in Scilit:
