Abstract

This invention discloses a method for identifying tamarind maturity based on aroma markers. Through systematic research, this invention, for the first time, discovers the correlation between eight characteristic aroma markers and tamarind maturity: for unripe tamarind, phenylacetaldehyde, sec-butylamine, 5-acetoxymethyl-2-furfural, and tea spiroane; for ripe tamarind, 5-hydroxymethylfurfural, octanal, p-cymene, and styrene. This method is simple to operate, has an accuracy rate of ≥98%, and is suitable for tamarind harvesting and grading, quality evaluation, and processing quality control.
