Abstract
Salty taste is an important sensory attribute in many foods, which stimulates the appetite. But high-salt diets bring many health risks, and salty alternatives should be explored to solve this problem. The salt-reducing agents may impart new odors in food. Therefore, the research should focus on developing a novel agent, which would replace the salt without affecting the taste of the food. Generally, some yeast extracts taste salty and can be used for replacing salts in foods without imparting any additional odor. In this study, we fractionated salty peptides from FA31 (Angel Yeast) by ultrafiltration, gel permeation chromatography, preparative liquid chromatography (pre-HPLC), with the combination of sensory evaluation, and the peptide sequence was identified by ESI-Q-TOF LC/MS as Asp-Asp, Glu-Asp, Asp-Asp-Asp, Ser-Pro-Glu, and Phe-Ile.
