Food astringency evaluating method and astringency evaluating apparatus

摘要

The food astringency evaluating method of the invention comprises a step in which an astringent component of a food is reacted with a peptide to form a complex, a step in which a prescribed measured value is obtained corresponding to the amount of formation of the complex, and a step in which the strength of astringency is determined from the obtained measured value based on a previously obtained correlation between strength of astringency and the prescribed measured value.
