“…Blossom honey is levorotatory in contrast to honeydew and some adulterated honey, which are normally dextrorotatory. This is a consequence of normal preponderance of fructose in the floral honey, which shows a negative specific rotation over glucose [22]. In this study all samples turned out to be levorotatory, with a mean value of −7.5 ± 0.8, indicating the floral origin of honeys and validating the higher fructose than glucose content found in the carbohydrate and pH analysis.…”

Characterizations of Apis mellifera honey produced in Southwest of Antioquia, an important coffee region of Colombia, have not been published in recent years. In the present work, seven samples of honey collected in the mentioned region, were physically (refractive index, specific rotation, density), chemically (moisture content, water activity, pH, free acidity, carbohydrates) and microbiologically (Clostridium, fungi and yeast) analyzed. The results show that the analyzed honeys meet both national (Resolución 1057 of 2010) and International (Codex-Stan 12 of 1981) standards for moisture content, free acidity, sucrose content and microbiological parameters, indicating their good quality. Fructose/glucose ratio, pH and specific rotation values indicate that the samples are blossom honeys. Key words: honey; honey bee; apis mellifera; physicochemical parameters; microbiology analysis; quality standards. Highlights• Southwest of Antioquia honeys have different water activity behavior than honeys from other Colombian regions.• Absence of microorganisms reveals the application of good manufacturing practices.• Fructose/glucose ratio, pH and specific rotation values indicate that the samples are blossom honeys.• Southwest of Antioquia honeys meet current Colombian and International regulation.Caracterización físico-química y microbiológica de la miel de Apis mellifera sp. del Suroeste de Antioquia, Colombia ResumenCaracterizaciones de miel de Apis mellifera producida en el Suroeste de Antioquia, una región cafetera de Colombia, no se han publicado recientemente. En el presente trabajo, siete muestras de miel recolectadas en la región mencionada, fueron físicamente (índice de refracción, rotación específica, densidad), químicamente (contenido de humedad, actividad acuosa, pH, acidez libre, carbohidratos), y microbiológicamente (Clostridium, hongos y levaduras) analizadas. Los resultados muestran que las mieles analizadas cumplen tanto los estándares nacionales (Resolución 1057 de 2010) como internacionales (Codex-Stan 12 de 1981) para contenido de humedad, acidez libre, contenido de sacarosa y los parámetros microbiológicos, indicando su buena calidad. Los valores de relación fructosa/glucosa, pH y rotación específica indican que las muestras son mieles florales.Palabras clave: miel de abejas; abeja melífera; apis mellifera; parámetros físico-químicos; análisis microbiológico; estándares de calidad.

Abstract. Honey is a nutritious product that is produced by honey bees. Its composition depends highly on the type of flowers utilised by the bee as well as the climatic conditions. This study was intended to evaluate the quality parameters of ten honey samples, from various regions in NorthWest of Algeria. The physicochemical property of the honeys [moisture, electrical conductivity, hydroxymethylfurfural, pH, acidity (free, total and lactone), reducing sugars, apparent sucrose, insoluble material, ash, and diastase activity] was determined. The moisture shows values of 14.21±0.18 % and 16.59±0.12%. The water insoluble material content ranged between 0.01 ± 0.03 to 0.67 ± 0.07%. The reducing sugars were between 66.3 ± 0.37 and 88 ± 0.23 %, mean percentages of apparent sucrose were 6.54 ± 0.23%. Honey samples showed an appropriate diastase number with an average of 12.35 ± 0.24, and their HMF (hydroxymethylfurfural) content ranging from 5.65 ±0.37 to 37.42 ± 0.55 mg/kg, Conductivity values ranged from 10 ± 0.54 to 606 ± 2.45 µS/cm. The ash content ranged from 0.019 ± 0.01% to 0.37 ± 0.05%. All honeys were acidic, having a pH in the range 3.7 ± 0.03-4.78 ± 0.05. The average values for free acidity in samples were between 10 ± 0.22 and 25 ± 0.5 meq/kg. Lactonic acidity ranges were from 2 ± 0.15 to 5 ± 0.15 meq/kg. Total acidity ranged from 12 ± 0.37 to 30 ± 0.65 meq/kg. All the samples were found to meet all major national and international honey specifications.

“…Przybylowski and Wilczyńska (2001), studying the mineral levels in honey samples from the Pomerania region, found an average value for Zn of 7.76 mg/kg, which exceeded the limits accepted by legislation in that region. Nanda et al (2003) studied the presence of mineral content in six floral honey samples from different botanical sources in Northern India and found considerable variations in the concentrations of Na, K, Ca, Fe, Cu, and Zn.…”

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
