“…This makes the pollen grains easy to decant with the supernatant liquid. The lack of pollen recovery due to using these techniques has lead many authors to look at ways to improve pollen sedimentation from honey (Agwu & Akanbi 1985, Gadbin 1979, Lieux 1972Louveaux 1966, Louveaux & Maurizio 1963, Louveaux et al 1970, 1978Low et al 1989, Maurizio 1951, White et al 1991. Low et al (1989) found significantly greater pollen sedimentation when honey was diluted with more water than the recommended, and was then centrifuged faster and longer than other techniques.…”

“…Pollen analysis of honey is used to determine a honey's floral type, quality, and origin (Barth 1990, Deans 1957, Feller-Demalsy et al 1987a1989, Lieux 1972, 1977, 1978Louveaux 1956, Maurizio 1951Maurizio & Louveaux 1965, White et al 1962. In many countries, import and export laws require three types of certification including verification of the honey's floral type, quality, and precise place of origin.…”

2004. The use of ETOH for the dilution of honey. -Grana 43: 174-182. ISSN 0017-3134.Since the beginning of honey production, certain honey types are preferred because they taste better, are better for cooking, or do not rapidly crystallize. Pollen found in honey is used to determine the honey's type. Techniques used to extract pollen from honey vary in the amount of honey examined, the amount of water used to dilute the honey, and the time and speed of centrifugation. These variations address the disparity in pollen recovery that is due to the specific gravity and sinking rates of the different pollen types. Ethyl alcohol (ETOH) was used as a dilution liquid for honey and compared to two water-dilution techniques, one with a short centrifugation time (1 minute) and the other using a long centrifugation time (10 minutes). The ETOH samples were centrifuged for 3 minutes. All samples were centrifuged at 4000 r.p.m. Significantly higher pollen concentration values were found in the ETOH-diluted samples. Pollen concentration values of the ETOH-diluted samples were 5.26 times greater than water-diluted, short centrifugation samples, and 3.26 times greater than water-diluted, long centrifugation samples. ETOH-diluted samples produced 16% more taxa than the water-diluted short centrifugation technique, and 10% more taxa than the water-diluted long centrifugation technique. The pollen spectra were not consistent across the three techniques. Additional research is needed to determine the efficiency of other ETOH concentrations in recovering pollen from honey. We recommend that the ETOH-dilution technique become the standard technique for the extraction of pollen from honey for pollen analyses because of the improved pollen recovery.

“…The only samples that show some differentiation (I, II, VIII and XV) were based on pollen types represented only as minor pollen, some of which were recorded only once in the pollen spectrum (Table II). Minor and trace pollen, due to its extremely low numbers, should be considered carefully before any assessment is made of their presence in honey sample (Lieux, 1978). A possible explanation for the random variation of samples in the study is the number of uncontrolled factors which can influence the presence of pollen types in honey samples, such as availability at the time, unbalance in the abundance of flowers among plants species, bee collection preferences, and others.…”

“…Pollen analysis of the honey samples revealed that the pollen grains in minor and rare groups contained various plant taxa. Lieux (1979) demonstrated that most of the taxa in the minor and trace groups were randomly mixed in the honey samples. The rare groups of pollen was recorded in samples 13 and 15 from the Karaman region.…”

For pollen analysis, 19 honey samples were collected from different localities in Ereğli, Karapınar, Ayrancı and Ulukışla regions of Konya, Karaman and Ulukışla, respectively, in November 2015. All investigated honey samples were multifloral because they contained secondary and minor pollen groups. The dominant group of pollen grains were determined as the families of Fabaceae in 2 samples and Scrophulariaceae in 5 other samples, Helianthus annuus in 1 sample and Zea mays in 1 sample. Secondary pollen groups consisted of the families of Amaranthaceae, Brassicaceae, Fabaceae, Poaceae, Rosaceae, Scrophulariaceae and genera of Centaurea, Cistus, Eucalyptus and Linaria. Pollen of 55 plant taxa were identified in examined honey samples of which 21 were classified on the family level, 30 were on the genera level, 1 was on the tribe level and 3 were on the species level. The total number of pollen (TPN-10) in 10 grams of honey ranged from 332 to 42496. According to the results of the TPN-10 analysis in honey samples, 3 samples were normal and others were poor. The taxa of Zea mays, Cistus, Poaceae, Scrophulariaceae and Amaranthaceae were found in pollen sources. Helianthus annuus and Brassicaceae were found in nectar sources. Fabaceae, Rosaceae, Eucalyptus, Centaurea were found in nectar and pollen sources and were identified in the honeys.
