Volatilomic Analysis in Peel, Pulp and Seed of Hass Avocado (Persea americana Mill.) From the Northern Subregion of Caldas by Gas Chromatography With Mass Spectrometry

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
The volatilome of Hass avocado peel, pulp, and seed was characterized using HS‐SPME‐GC–MS, revealing 87 VOCs with tissue‐specific profiles. Terpenes dominated the seed, while esters and aldehydes were more abundant in the pulp, and oxygenated terpenes were prominent in the peel.
