Resumen: Venezuelan stingless bee honeys characterized by multivariate analysis of physicochemical properties. (Vit Olivier, Patricia; Persano Oddo, Livia; Marano, Maria Luisa y Salas de Mejias, Eddy) Abstract Stingless bee honey samples collected from 27 nests in Venezuela, were analysed for ten compositional factors (acidity, ash, electrical conductivity, diastase activity, hydroxymethylfurfural, invertase activity, nitrogen, reducing sugars, sucrose and water). The entomological origin of the honeys based on these factors was explored using three methods of multivariate analysis. Clustering was adequate to separate the honey samples into two stingless bee tribes with the exception of honeys from one genus ofTrigonini. Principal component analysis confirmed these findings and grouped the honeys to species level. Although discriminant analysis of the ten quality factors under consideration positioned all the samples in their respective entomological group, lowering the number of variables to reducing sugars, sucrose and diastase activity was still satisfactory for a correct classification. A fourth variable that could be used to assign correct membership was either acidity or nitrogen content. © Inra/DIB/AGIB/Elsevier, Paris
