MONTENEGRO, G et al. Analysis of volatile compounds in three unifloral native Chilean honeys. Phyton (B. Aires) [online]. 2009, vol.78, n.1, pp.61-65. ISSN 1851-5657.

Three unifloral honeys were identified by the pronounced presence of specific compounds by means of sensorial analysis and SPME-GC-MS. Smoky and resinous (‘propolis') odors characterized unifloral "quillay" (Quillaja saponaria) honey. "Corontillo" (Escallonia pulverulenta) honey was characterized by caramel and vanillin aromas, and "ulmo" (Eucryphia cordifolia) honey by having an anise scent with a floral jasmine note. Safranal was a useful marker for "corontillo" honey. Isophorone and cetoisophorone were the distinctive compounds of unifloral "ulmo" honey. In "quillay" honeys, megastigmatrienone, 2-p-hydroxyphenylalcohol and minor quantities of β-pinene and linalool oxide were correlated with their sensory properties such as resinous.

Palabras clave : Ulmo honey; Escallonia or "corontillo" honey; Quillaja honey; SPME-GC-MS analysis.
