Botany origin and protein content of homemade honeys from Galicia hives (NW Spain)

The botanic origin and the protein content of 15 honeys from small bee farms exploitations of Galicia, for family consume, were studied; the aim is to check if the protein wealth and the pollen wealth are dependent parameters. Seven honeys resulted to be Rhamnus frangula unifloral (pollen patterns with low diversity), two Castanea sativa Miller unifloral, other one heather unifloral, and five was multifloral honeys of various pollen patterns (four Castanea predominant and one Rhamnus frangula predominant). Their pollen wealth was low; eight honeys classified in the Maurizio Class I, 3 in Class II, 2 in Class III, and one in Maurizio Class IV. There has been a wide variability in its protein content (0.09- 4.83 mg prot./g honey). The relative amount of pollen from different taxa has a direct or inverse proportionality to wealth protein.

Contribución al conocimiento melitopalinológico de Sierra Morena

Sc ha estudiado al microscopio óptico el sedimento de once muestras de miel de diversas localidades del este de Sierra Morena. Se pone de manifiesto que, en este área, el néctar de flores es la principal fuenle de miel para Apis mellifera,siendo la mielada poco importante. Echium plantagineum, Lavandula stoechas y Eucalyptus camaldulensis son las principales fuentes de miel en este área, en tanto que Cistus ladanifer, C. albidus, Olea europaea y Quercus sp. lo son de polen.
