“…As long as the values do not overcome the standard limit (20%), they are declared conform and no danger of fermentation is present. The obtained values are comparable with other studies on honey from Romania [ 17 , 20 , 22 , 23 , 26 , 30 , 31 , 32 ]. Electrical conductivity is another parameter used in honey authentication; monofloral light honeys must have low values of this parameter.…”

“…The available scientific literature indicates increasing published research data regarding the chemical composition, bioactivity, the profile and content of flavonoids and phenolic acids in Romanian honeys [ 17 , 20 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. This is due to the variety and quality of Romanian honey, the fact that agriculture is less developed and chemicalized, and the fact that different landscapes provide very good “raw material” for the bees (nectar, pollen and honeydew), materials clean of any contaminants and having a huge variety of botanical origins.…”

Bioactive molecules from the class of polyphenols are secondary metabolites from plants. They are present in honey from nectar and pollen of flowers from where honeybees collect the “raw material” to produce honey. Robinia pseudoacacia and Helianthus annuus are important sources of nectar for production of two monofloral honeys with specific characteristics and important biological activity. A high-performance liquid chromatography–electro spray ionization–mass spectrometry (HPLC–ESI–MS) separation method was used to determine polyphenolic profile from the two types of Romanian unifloral honeys. Robinia and Helianthus honey showed a common flavonoid profile, where pinobanksin (1.61 and 1.94 mg/kg), pinocembrin (0.97 and 1.78 mg/kg) and chrysin (0.96 and 1.08 mg/kg) were identified in both honey types; a characteristic flavonoid profile in which acacetin (1.20 mg/kg), specific only for Robinia honey, was shown; and quercetin (1.85 mg/kg), luteolin (21.03 mg/kg), kaempferol (0.96 mg/kg) and galangin (1.89 mg/kg), specific for Helianthus honey, were shown. In addition, different phenolic acids were found in Robinia and Helianthus honey, while abscisic acid was found only in Robinia honey. Abscisic acid was correlated with geographical location; the samples collected from the south part of Romania had higher amounts, due to climatic conditions. Acacetin was proposed as a biochemical marker for Romanian Robinia honey and quercetin for Helianthus honey.

“…According to Venir, Spaziani, and Maltini (2010), honey fructose to glucose ratio of 1.14 indicates a tendency to granulate more rapidly than honey with a ratio significantly above 1.58. As observed in previous studies that values above 1.3 had a slower granulation tendency (Dobre, Escuredo, Rodriguez-Flores, & Seijo, 2014). The F/G ratio of around 1.2 found in our samples was within the range reported in other studies (Bentabol, García, Galdón, Rodríguez, & Romero, 2011;Dobre et al, 2012).…”

Honey is a viscous, aromatic, sweet food that is consumed and enjoyed by people all around the world. For this reason, it requires certain standards and norms that guarantee its identity and quality so that consumers feel they can safely consume it, and at the same time, the product can enjoy circulation in the internal market and access to the external market "Council directive, 2001/110/RC, 2002." Many regions of the world have recorded honeybee losses in recent years. The cause of the decline in bee numbers has not been

“…The average TP and TF values were slightly higher than those reported for Romanian acacia, rape and honeydew honeys, Serbian polyfloral honeys, Malaysian acacia honeys and polyfloral, honeydew and acacia honeys from Burkina Faso . Even if the investigated honey samples are old samples, the bioactive properties are within the natural range of variation, storage condition affecting only to a minor degree the honey therapeutic potential …”

Introduction Honey has been considered to have therapeutic properties since ancient times and among the factors responsible for such activity are phenolic compounds including phenolic acids and flavonoids from different natural sources. Objective This study investigated the phenolic compounds profile and bioactive properties of different honey types from Romanian flora in order to develop reliable tools for honey floral origin, thus contributing to the honey traceability in the European Union context. Material and methods Thirty‐three honey samples were examined, including unifloral (acacia and rape), polyfloral, honeydew honeys and mixture honeys. Phenolic acids and flavonoids were isolated from the water soluble honey matrix using a solid‐phase extraction (SPE) method and analysed by ultra‐high‐performance liquid chromatography diode array detector electrospray ionisation mass spectrometry (UHPLC‐DAD‐ESI/MS). Honey bioactive properties were measured in honey dissolved in 80% ethanol using UV‐visible spectrophotometric methods. Multivariate statistical tools (principal component analysis and hierarchical clustering analysis) were used for honey classification. Results The results of this study confirm that honey samples had similar, but quantitatively different, phenolic acids and flavonoids profiles and bioactive properties, related with honey floral source. Coloured honeys, such as honeydew honey, show high phenolic composition and bioactive properties and implicitly a high therapeutic potential compared with the other floral honeys. Conclusion Distinctive clusters obtained by principal component analysis enabled us to consider that honeydew and polyfloral honeys could be distinguished from acacia and rape honey with the analytical methods developed. Based on this study, the methods might be promising tools for honey traceability, which needs to be explored on a larger set of samples with different regional floral origins in future studies.
