How soil type (gypsum or limestone) influences the properties and composition of thyme honey

View Article: PubMed Central - PubMed

ABSTRACT

Background and aims: The objective of this work was to determine the influence of the soil substrate on the characteristics and properties of a specific type of honey. As such, we analysed the features of a typical single-flower honey, thyme honey, produced in a specific Mediterranean region. Thymus is a genus of aromatic perennial plants that are native to Europe, North Africa and Asia.

Methods: A total of 70 honey samples from hives situated on limestone (38 samples) or gypsum soils (32 samples) were studied. The physical and chemical properties of each samples were analyzed using standard assays.

Results: Within the same geographical area and despite a similar thyme pollen content, we observed variation in the physicochemical, antioxidant and sensorial characteristics of monofloral honeys. The quantification of certain physicochemical parameters of the honey indicated these features were influenced by the soil type. Indeed, the soil type of the hives’ settlement area, limestone or gypsum, influences the conductivity, antioxidant capacity, colour and floristic composition.

Conclusions: The present work demonstrates that soil type (gypsum or limestone) influences the characteristics of honey, potentially providing added market value to these products.

Fig5: Pollen diversity in honeys samples

Mentions: The pollen types in the honey samples were analysed and for each type of honey, we chose to represent the most significant taxa (at the family or genus level) for clarity. Anemophilous species of the Fagaceae family (Quercus ilex subsp. ballota (Desf.) Samp. and Quercus faginea Lam) were more strongly represented in the honeys on limestone. Indeed, these species form forests on limestone, whereas on the gypsum substrates in the area studied they are found as isolated individuals. In the honey from monofloral thyme isolated from apiaries located on gypsum, the families and genera best represented were Brassicaceae, Caryophyllaceae, Scrophulariaceae, Asteraceae, Fabaceae, Rosaceae and the genus Helianthemum (Cistaceae) and Teucrium (Lamiaceae). By contrast, in the honey from apiaries located on limestone the Salicaceae, Boraginaceae, Cistaceae, Fagaceae and Rosmarinus officinalis L (Lamiaceae) families predominate (Fig. 5; see full details in Additional file 1).Fig. 5
