“…Thus, the determination of HMF is an indicator of honey quality because when it is formed, it indicates loss of enzymatic activity enzymes of glucose oxidase, for example. The average value obtained was 5.14 mg.kg -1 indicating that the sample is below the maximum value established by national and international legislations, and it is also below the values found by Bendini and Souza (2008) The honey acidity is due to the variation of organic acids caused by different sources of nectar, by the action of the glucose oxidase enzyme which generates gluconic acid, by the action of bacteria during honey ripening, and even by the amount of minerals found in honey.…”

ResumoProdutores de mandioca da região de Marília, Estado de São Paulo, estão consorciando a atividade da apicultura em meio à cultura visando diversificar a renda obtida pela propriedade rural. Este trabalho teve como objetivo avaliar a qualidade físico-química e microbiológica do mel produzido por abelhas Apis mellifera africanizadas, elaborado a partir de flores de mandioca, no ano de 2008. Foram realizadas análises de pH, sólidos solúveis totais (SST), acidez, umidade, açúcares redutores e totais, sacarose aparente, hidroximetilfurfural, cor, cinzas, proteínas, sólidos insolúveis em água, atividade diastásica, teor de minerais e monitoramento dos teores de ácido cianídrico (HCN), além de avaliações microbiológicas. O mel apresentou características físico-químicas e microbiológicas favoráveis à comercialização, com exceção da sacarose aparente e da acidez, sendo necessária atenção na maturação do mel no momento da coleta e melhor monitoramento nas fases de produção e processamento. A comercialização brasileira do mel de mandioca é ainda pouco explorada, mas pode ser amplamente disseminada no mercado, visto que os valores de HCN não apresentaram risco ao consumidor e a produção do mel paralelamente ao plantio da mandioca proporciona uma alternativa de aumento na renda familiar. Palavras-chave: Manihot esculenta Crantz; ácido cianídrico; apicultura. AbstractCassava producers in the region of Marília-São Paulo are integrating their farming activity with beekeeping to diversify their income. The aim of this study was to evaluate the physicochemical and microbiological quality of honey samples produced by Africanized honeybees Apis mellifera from cassava flower in 2008. Analysis were carried out for pH, total soluble solids (TSS), acidity, moisture, reducing and total sugars, apparent sucrose, hydroxymethylfurfural, color, ash, proteins, water insoluble solids, diastasic activity, mineral content, microbiological evaluations, and mineral and hydrocyanic acid (HCN) content. The honey samples showed physicochemical and microbiological characteristics favorable to commercialization, with the exception of apparent sucrose and acidity, which show the need for a narrow focus of attention to the honey maturation degree at the harvest time and more careful monitoring during production and processing. The commercialization of Brazilian cassava honey, still little explored, can be widely spread in the market since the levels of hydrocyanic acid (HCN) showed no consumption risk; in addition the simultaneous production of honey and cassava provides an alternative to family income increase.

“…63 Despite not being required by Brazilian legislation, 50 for pH (range of 3.20 to 4.60), the values were within the allowed Brazilian standards, like in honey from cashew flowers, around, 3.67. 40 The content of HMF in honeys is indicative of freshness of honey samples. 30 The diastase activity is a parameter related to the maturity and freshness of honey and diastase (α-amylase) is an enzyme present in honey.…”

“…20 The cashew honey from Piauí was shown to be dark colored and to have pronounced acidity and a relatively high amount of amino acids, so, the geographical origin of honey is an important parameter in this area of research. 40 In the semi-arid region of northeast of Brazil, there is a diversified flora. In the Bahia State, many types of farmhouse honey are produced.…”

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.

“…Moisture is the key criterion that determines the ability of honey to remain fresh and free of fermentation (BOGDANOV et al, 1999). Bendini and Souza (2008) found values of moisture varying from 16.50 to 19.20% in honey samples originating from cashew flowers from the city of Cascavel, Ceará State. These results are close to those obtained in the present study.…”

ResumoEste trabalho avaliou propriedades físico-químicas, teores de proteína e minerais em méis do Ceará, um dos principais exportadores do País. Também foi analisada a importância nutricional com relação aos minerais detectados. As propriedades físico-químicas foram determinadas pelos métodos da AOAC e CAC, o conteúdo de proteína pelo método de Bradford e os minerais por espectrometria de absorção atômica. Todas as análises foram feitas em triplicata. Os níveis dos macrominerais sódio (Na), potássio (K), cálcio (Ca), e magnésio (Mg) variaram de 1,80-47,20, 21,30-1513,30, 14,58-304,82 e 2,48-28,33 mg/kg, respectivamente, e os elementos traços ferro (Fe), cobre (Cu), manganês (Mn), zinco (Zn), selênio (Se), e cromo (Cr) variaram de 0,12-8,76, 0,07-1,29, 0,06-1,96, 0,07-1,85 mg/kg, 0,36 × 10 -3 -62,00 × 10 -3 e 22,50 × 10 -3 -170,33 × 10 -3 µg/kg, respectivamente. A amostra de Myracrodruon urundeuva apresentou altos teores dos principais minerais (Na, K, Ca, e Mg). O teor de proteínas para o mel de Anacardium occidentale foi o maior (1121,00 µg/g) entre as amostras de méis analisadas. Entre os minerais, detectados, K apresentou a maior concentração seguido por Ca, Na, e Mg. A pesquisa de elementos traços pode indicar contaminação ambiental. As amostras de méis estudadas apresentaram-se livres de contaminação por elementos traço, excetuando-se quanto ao Mn, em que apenas a amostra proveniente de Piptadenia moniliformis apresentou-se dentro da legislação. As variações dos constituintes químicos devem-se provavelmente às variadas origens florais e os teores de proteínas e minerais ratificam a importância nutricional dos méis do Ceará. Palavras-chave: mel de Apis mellifera; origem floral; importância nutricional. AbstractThis study evaluated the physicochemical properties and protein and mineral content of honey samples from Ceará State, Northeastern Brazil, one of the major honey exporters in the country. Nutritional importance of the minerals detected was also analyzed. Physicochemical properties were examined according to the AOAC and CAC official methods; the protein content was determined using the Bradford method, and the minerals were analyzed by atomic absorption spectrometry. All analyses were performed in triplicate. The levels of macrominerals sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg) varied from 1. 80-47.20, 21.30-1513.30, 14.58-304.82, and 2.48-28.33 mg/kg, respectively, and the trace elements iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), selenium (Se), and chromium (Cr) varied from 0.12-8.76, 0.07-1.29, 0.06-1.96, 0.07-1.85 mg/kg, 0
