Resumo: O objetivo deste trabalho foi avaliar a origem floral, a qualidade físico-química e a capacidade antioxidante de 15 amostras de mel, da região semi-árida do nordeste do Brasil e correlacionar os dados com a cor e o conteúdo total de fenóis (TPC). Observou-se uma predominância da cor âmbar. A maioria das amostras foi classificada como polifloral e, apenas duas amostras (amarelo claro) foram de origem monofloral. Os valores de TPC variaram de 27,0 a 92,7 mg EAG 100 g -1 de mel, sendo mais elevados em amostras mais escuras. Todas as amostras mostraram capacidade de sequestrar radicais DPPH  e poder redutor analisado pelos métodos de FRAP e CUPRAC, com melhor desempenho em amostras mais escuras. O TPC apresenta boa correlação (p<0,05) com os resultados relacionados à capacidade antioxidante. Foram observadas correlações significativas (p<0,01) entre a cor, o TPC (0,82) e também com o poder redutor, via CUPRAC (0,66). A cor mais escura do mel é um indicativo de maior teor de fenóis e maior capacidade antioxidante. As características aqui descritas enriquecem as propriedades de alimento funcional do mel e contribuem para o desenvolvimento da economia regional, fornecendo alternativas para a geração de renda familiar regional.Palavras-chave: Teor total de fenóis; capacidade antioxidante; análise físico-química; mel. AbstractThe aim of this work was to evaluate floral origin, physicochemical quality and antioxidant capacity of 15 honey samples, from a semi-arid region in the northeast of Brazil and to correlate data with color and total phenolic content (TPC). A predominance of amber color was observed. The majority of samples were classified as polifloral and only two samples (the light yellow ones) were monofloral. TPC values ranged from 27.0 to 92.7 mg GAE 100 g -1 of honey, being higher in darker samples. All samples had ability to scavenge DPPH  radicals and showed reducing potential analyzed by FRAP and CUPRAC methods, with the highest performance obtained in darker samples. TPC shows good positive correlations (p<0.05) with the methods used to evaluate antioxidant capacity. Significant correlations (p<0.01) between color and TPC (0.82) and also with reducing power, using CUPRAC (0.66) were observed. The darker color of honey is indicative of higher phenol content and antioxidant capacity. The reported characteristics give an enhanced functional food property to honey and contribute to the development of the regional economy, providing an alternative to family income increase.

“…Due to unique chemical composition of eucalyptus honey it had TRS between 69% to 72% and 75% to 78% respectively [38][39][40][41]. After comparing the three states it was observed that total reducing sugars in honey samples falls between 65% to 78.5%.…”

Honey is considered as natural and healthy product that has a highly concentrated solution of a complex mixture of carbohydrates. The quality of a honey depends on its geographical and botanical origin. Therefore, classification of honey according to geographical origin is of great interest. In this study, it is aimed to develop classification models of honey harvested in India based on geographical and botanical origin via GIS analysis. Seventy-seven honey samples were taken from different regions of North India (Punjab, Uttar Pradesh and Rajasthan States) and characterization was carried out on the basis of their quality parameters (moisture content, color, hydroxymethylfurfural (HMF), total reducing sugars, sucrose and fructose/glucose ratio) and these parameters were mapped and interpolated with GIS technologies.

“…The composition of honey varies with the feeding of the bees [14]. Honey has been reported to contain more than 180 substances and is considered as an important part of traditional medicine [8,15]. Honey has numerous uses and functional applications worldwide such as in food systems, religious and magical ceremonies as well as in human and veterinary medicine [16].…”

ABSTRACT. The objective of this study was to assess quality of Tigray honey and content of selected metals (Cu, Co, Cr, Ni, Fe, Zn, Cd, Mn). Thirty honey samples from various areas of Tigray Region, Ethiopia were collected and analyzed for major quality parameters (pH, electrical conductivity, moisture content, ash content and levels of selected metals). Moisture content had a value of 18.6 (minimum) and 18.8 (maximum) indicating optimum harvesting and good degree of maturity. All honeys analyzed in this work had ash contents less than 0.6%, indicating that they were more likely to be floral than honeydew origin. Electrical conductivity varies from 8.27 ± 0.02 µS/cm (Hawzene) to 33.5 ± 0.2 µS/cm (Abiy Adi). Values recorded for honey pH ranged from 3.82 ± 0.01 (Hawzen) and 4.45 ± 0.01 (Abiy Adi). In general the Tigray honey shows relatively acidic behavior which is similar to other honeys in the world. The concentration of trace metals in honey was more or less different depending on the sampling area. The highest concentration was observed for iron, copper, nickel, manganese, zinc, chromium, cobalt and cadmium in that order. The highest concentration of metals was observed in Adigrat honey and then Hagereselam, Abiy Adi, Hawezene and the least for Atsbi.
