Abstract

Palynological characteristics of sweet chestnut honeys from Galicia (NW Spain).

Abstract

Pollen analyses were carried out on 83 honey samples from Galicia in which Castanea pollen constituted over 70% of total pollen (over half had more than 80%). The mean number of pollen types found in a sample was 21 (range 8-35) and mean pollen content was 263 840/10 g honey (Maurizio's class III). Other pollens in these honeys included Rubus, Erica, Eucalyptus, Cytisus and Campanula. Chestnut honey is produced principally in Lugo and Ourense provinces. The main difference from chestnut honeys produced elsewhere in Spain is that Galician honeys do not contain Lavandula stoechas, Cistus ladanifer and Clematis vitalba pollens, and Calluna vulgaris is rare.
