“…Beekeepers tend to move their hives following the diferent seasons and fower bloom to increase honey production [33]. According to a survey with Lebanese beekeepers [14], 87% of Lebanese beekeepers practice transhumance, with the lowest rate of migratory beekeeping found for beekeepers of the Baalbeck-Hermel region which may explain this distinction of the honey samples collected from this region. Considering the small area of Lebanon, felds with plants uniformity do not exist.…”

“…In Lebanon, beekeeping is a main activity in the agricultural sector. It is one of the oldest professions in the country and has an important economic impact [14]. Because of the small surface of the country, ofering within its 10,452 km 2 , many geographical and topographical morphologies with diferent altitudes, ranging from 0 to 3000 meters, and 4 distinct seasons, honey production in Lebanon is essentially multiforal [15].…”

“…In Lebanon, vertical transhumance is the base of professional beekeeping. It consists in moving hives from higher to lower altitudes according to the seasonal changes, the temperature variations, and the blooming of fowers [14]. Tis frequent practice makes the authentication of honeys according to their geographical and botanical origin even more difcult and challenging.…”

Honey is considered as a premium food produced by honeybees. It is highly appreciated by consumers around the world and raises a major concern nowadays which is ensuring its authenticity in respect to its production and its botanical origin. In Lebanon, honey is mainly multifloral which makes its authentication rather difficult. While mid-infrared (MIR) spectroscopy combined with multivariate analysis has proven to be successful in authenticating unifloral honey, the challenge with Lebanese honey lies in assessing its performance with multifloral honey. Therefore, this work aims to test the performance of common components analysis (CCA) applied on mid-infrared spectra in the authentication of multifloral Lebanese honey. For this purpose, 96 multifloral Lebanese honey samples of different floral sources were collected from different regions of the Lebanese territory and analyzed using MIR spectroscopy. CCA applied to the spectral data, allowed a separation between honeydew honey samples and floral honey samples. In addition, honey samples collected from the Bekaa plain region were differentiated from the other honey samples collected from all the other Lebanese geographical regions. This discrimination between the groups of honey samples is based essentially on their sugar composition.
