 es Clasificación del Origen Botánico de la Miel Mediante la Combinación de Análisis Multivariado y Recuento de Polen
Corbella, Eduardo & Cozzolino, Daniel

Resumen

Este estudio reporta la combinación de técnicas de análisis multivariado y de polen para clasificar el origen botánico de muestras de miel provenientes de Uruguay. Muestras de miel de diversos orígenes botánicos, a saber Eucalyptus check for this species in other resources spp. (n = 10), Lotus check for this species in other resources spp. (n = 12), Salix check for this species in other resources spp. (n = 5), mil flores ( Myrtaceae check for this species in other resources spp.) (n = 12) y coronilla ( Scutia buxifolia check for this species in other resources Reissek) (n = 10) fueron analizadas usando Melisopalinología (identificación del polen). Análisis de componentes principales (APC) y de discriminantes lineales (ADL) fueron utilizados para clasificar las muestras de la miel de acuerdo a su origen botánico basado en el conteo de polen. Las muestras de miel que contenían más de un 70% de polen de Eucaliptus, Lotus y Scutia buxifolia fueron clasificadas correctamente en un 100% de los casos. Mientras que las muestras de miel identificadas como de Myrtaceae check for this species in other resources spp. y Salix fueron clasificadas correctamente en un 80 y 66% de los casos. El uso de APC y de ADL combinado con la identificación del polen probó ser una herramienta útil para caracterizar muestras de miel de diversos origenes.

 en Combining Multivariate Analysis and Pollen Count to Classify Honey Samples Accordingly to Different Botanical Origins
Corbella, Eduardo & Cozzolino, Daniel

Abstract

This study reports the combination of multivariate techniques and pollen count analysis to classify honey samples accordingly to botanical sources, in samples from Uruguay. Honey samples from different botanical origins, namely Eucalyptus check for this species in other resources spp. (n = 10), Lotus check for this species in other resources spp. (n = 12), Salix check for this species in other resources spp. (n = 5), "mil flores" ( Myrtaceae check for this species in other resources spp.) (n = 12) and coronilla ( Scutia buxifolia check for this species in other resources Reissek) (n = 10) were analysed using Melissopalynology (pollen identification). Principal component analysis (PCA) and linear discriminant analysis (LDA) were used to classify the honey samples accordingly to their botanical origin based on a pollen count. Honey samples of higher percentage (> 70%) of Eucalyptus, Lotus and Scutia pollen were 100% correctly classified, whilst samples from Myrtaceae check for this species in other resources spp. and Salix were 80 and 66% correctly classified, respectively. The use of PCA and LDA combined with pollen identification proved useful in characterizing honey samples from different botanical origins.
