Classification of unifloral honeys using multivariate analysis

Journal of Essential Oil Research, 2015
The aim of this study was to investigate the physicochemical properties (moisture content, conductivity, 5-HMF, fructose, glucose, L*, a* and b* color parameters) and volatile compounds of Romanian honeys. According to the melissopalynological analysis, the honey samples were of the following botanical origins: acacia, sunflower and tilia.

Effects of conditioning on HMF content in unifloral honeys

Food Chemistry, 2004
Abstract HMF (5-hydroxymethylfurfural) is considered an important quality parameter for honey and maximum values are fixed by the European Directive no.110 (2001). In this paper, the HMF levels during the heating process of four unifloral Sicilian honeys (Orange, Eucalyptus, Sulla, Chestnut) were determined; the kinetics of HMF formation were also ...

Flavonoid pattern of sage (Salvia officinalis L.) unifloral honey

Food Chemistry, 2008
The aim of the present paper was to determine the flavonoids in monofloral sage (Salvia officinalis L.) honey which is characteristic and specific for the area of Croatian coast and islands. For that purpose 38 sage honey samples from two production seasons were analysed.

Characterisation of Moroccan unifloral honeys using multivariate analysis

European Food Research and Technology, 2003
Physicochemical properties of 39 samples of Moroccan honeys were analysed; 30 parameters were measured, including water content, pH, acidity (free and lactonic), HMF, diastase activity, electrical conductivity, mineral and sugar content, and colour. In addition, the characterisation of the five unifloral honeys (Eucalyptus sp., Citrus sp., Lythrum sp.,

Unifloral Honeys: Chemical Conversion and Pollen Reduction

Grana, 1994
Abstract Physico-chemical and pollen analyses were made of unifloral samples of nectar, crop content and honey. The samples were obtained by carrying out cage experiments exclusively with one plant species. The investigations of four plant species are presented: Centaurea montana, Coriandrum sativum. Euphorbia lathyris and Rubus idaeus.

Palynological characteristics of different unifloral honeys from Greece

Grana, 2004
Three hundred and twenty-nine Greek honey samples of different botanical and geographical origin were collected and examined by organoleptic evaluation, melissopalynological analysis, measurement of electrical conductivity and colour. The results showed that 208 samples were unifloral with 178 of them representing the main types of unifloral honey ...

Antioxidant capacity and correlated characteristics of 14 unifloral honeys

Journal of Apicultural Research, 1998
SUMMARYThe water-soluble antioxidant capacity of 19 samples of honey from 14 different floral sources was determined by a spectrophotometric assay. The highest concentration of antioxidants measured was 20.3 times that of the lowest, showing that great variation exists in the chemical nature of honey from different floral sources.
