Unifloral honey

Pollen analysis in combination with other techniques is still an effective tool for the authentication of the botanical origin of honey (Persano Oddo et ah, 1995 Von der Ohe et ah, 2004). It can distinguish polyfloral and different types of unifloral honeys (Mateo and Bosch-Reig, 1998). It can also indicate the percentages of different nectar contributions in honey products. A polymerase chain reaction technique and an...

Seventy different unifloral honey samples of specific botanical and geographical origins were analysed by an electronic nose. Fourteen samples from Robinia pseudoacacia L., 30 from Rhododendron spp. and 20 from Citrus spp. were of Italian origin, and six samples from Robinia pseudoacacia honey were of Hungarian origin. All samples were provided by the Istituto Nazionale di Apicoltura (Bologna, Italy) and their...

The extraction of ascorbic acid with metaphosphoric acid and the reaction of a citrate-buffered solution of analyte with a known amount of 2,6-dichlor-ophenol indophenol is the base for the colorimetric method developed by Bessey (1938). This method, which was later applied by Haydak et al. (1942) to honey, takes advantage of the fact that the absorbance decrease at 520 nm is proportional to the concentration of ascorbic acid. More recently, Ferreira et al. (2009) measured the concentration of vitamin C in three Portuguese unifloral honeys using the same principle, but unfortunately no validation parameters were provided in this study.
