Organoleptic Evaluation of Amomi Fructus and Its Further Background Verified via Morphological Measurement and GC Coupled with E-Nose

الملخص EN

The present study investigated the maneuverability and reasonability of sensory analysis, which has been applied in TCM identification for a long time.

Ten assessors were trained and generated the human panel to carry out the organoleptic evaluation of twenty-five batches of Sha-Ren samples.

Accordingly, samples were scored from 0 (lowest) to 10 (highest) for sensory attributes.

Based on this, samples were divided into three classes: high class (Yang-Chun-Sha from Guang-Dong), moderate class (Yang-Chun-Sha samples from Yun-Nan and Guang-Xi), and low class (Lv-Qiao-Sha from marketplaces).

For further background, three instrumental approaches were employed: morphological measurement with three indices (longitudinal diameter, transverse diameter, and 100-fruit weight), GC for determination of bornyl acetate contents, and E-nose for aromatic fingerprint.

It is demonstrated in the results that GC and E-nose analyses were in great agreement with organoleptic evaluation.

It gives insights into further studies on searching better morphological indicators and improving discriminant model of E-nose.
