Validation of preferred salt concentration in soup based on a randomized blinded experiment in multiple regions in Japan—influence of umami (L-glutamate) on saltiness and palatability of low-salt solutions

H. Hayabuchi, R. Morita, et al.

Discover how monosodium L-glutamate (MSG) can elevate the palatability of low-salt soups! This groundbreaking study explores the effects of MSG on the perceived saltiness and taste satisfaction in a controlled taste test with 584 participants, conducted by Hitomi Hayabuchi and colleagues. The findings suggest MSG could be the secret to enjoying low-salt diets without sacrificing flavor.

Abstract

This study investigated the effect of monosodium L-glutamate (MSG) on the saltiness and palatability of low-salt soup solutions. 584 participants tasted 0.3%, 0.6%, and 0.9% NaCl solutions with or without 0.3% MSG. Saltiness increased with NaCl concentration, and MSG significantly enhanced saltiness at the 0.3% NaCl level. Palatability was higher for solutions with MSG, especially the 0.3% NaCl + MSG solution, which was twice as palatable as the 0.3% NaCl solution without MSG. These results suggest that umami can compensate for palatability loss due to salt reduction, allowing for a reduction from 0.9% to 0.3% NaCl without compromising palatability.
