“…The activation energy, E a , as described by Arrhenius Model, has proven to be a most valuable parameter in investigating the temperature sensitivity of the samples for comparison purposes (Sopade et al 2003). However, if a lot of papers report data on honeys viscosities at a specified temperature (i.e.…”

“…The subject has been widely studied and there is extensive literature available on the rheological properties of the honey collected in different parts of the world (Bhandari et al, 1999, Gómez-Díaz et al, 2006, Kayacier & Karaman, 2008Lazaridou et al, 2004;Mossel et al, 2000, Oh & Yoo, 2011Trávníček et al, 2012;Yoo, 2004,). Most of the reports on the subject maintain that honey is a Newtonian fluid whose viscosity depends on temperature and water content (Abu-Jdayil et al, 2002;Al-Malah et al, 2001;Bakier, 2007;Junzheng and Changying, 1998;Sopade et al, 2002;Yanniotis et al, 2006;Zaitoun et al, 2001). Some works indicate that liquid honey may have pseudoplastic properties (Gomez-Diaz et al, 2006;Mehryar et al, 2013) or thixotropic characteristics (White, 1978).…”

“…Some works indicate that liquid honey may have pseudoplastic properties (Gomez-Diaz et al, 2006;Mehryar et al, 2013) or thixotropic characteristics (White, 1978). To identify the rheological properties of honey, steady shear (Mossel et al, 2000;Recondo et al, 2006;Sopade et al, 2002;Yanniotis et al, 2006) and dynamic measurements have been used (Ahmed et al, bakier et AL.…”

A b s t r a c t The paper presents the results of rheological measurements conducted on three types of Polish honey: rape, multi-floral, and buckwheat honeys. The investigations involved identification of the properties of the honeys in both liquefied (by heating) as well as crystallised states. Both steady shear as well as dynamic rheological tests were performed. As a result, it was possible to show that the liquefied honeys behave like Newtonian fluids. Good agreement of the results between the rotary shear and oscillation rotary tests was observed, thus fulfilling the Cox-Mertz rule. The structure of the honeys was subjected to qualitative scrutiny by analysing photographs of the crystals taken in the conditions of shearing interferometry. The quantitative analysis was made by presenting a numerical distribution of crystal colonies with reference to the maximum dimensions of individual crystals. The geometric measurements of the crystals were carried out using analiSIS software. In the crystallised form, the media showed a thixotropic effect, and their apparent viscosity was many times higher than the dynamic viscosity in the liquid state. After plasticising by deformation with an increasing shear rate of up to 450s -1 , the equilibrium melting curves of the crystallised honeys were described by the Ostwald-de Waele model. One particular reason for the research was to show that the results obtained for the honeys crystallised by the steady shear method, were qualitatively different from the results obtained in the dynamic measurements. The Cox-Mertz rule cannot be applied for the crystallised honeys.

RESUME : Dans le cadre de la réforme du LMD (Licence -Master -Doctorat), et pour initier les étudiants à l'analyse scientifique, nous avons mis en place un enseignement sous la forme de projets tuteurés en L3 Physique à l'Université de Montpellier dans le Département d'Enseignement de Physique (DEPHY). La mise en place de ce module, les thèmes abordés, les modalités de contrôle des connaissances, le retour d'expérience sur 2 ans de fonctionnement, l'avis des étudiants sur cette unité d'enseignement sont présentés dans cette communication. Pour illustrer notre propos, nous mettons l'accent sur quelques thèmes qui ont motivé les étudiants et ont conduit à la réalisation de très bons projets.
