Caracterización físicoquímica de miel de angelita Tetragonisca angustula (Latreille, 1811) producida en Esmeraldas, Ecuador / Physicochemical characterization of “angelita” Tetragonisca angustula (Latreille, 1811) honey produced in Esmeraldas, Ecuador

En Ecuador la megabiodiversidad está presente también en las mieles producidas en potes de cerumen, las cuales no están incluidas en las normas técnicas de calidad del Instituto Ecuatoriano de Normalización NET INEN 1572. Las normas de miel sólo se refieren a la miel producida por la abeja comercial Apis mellifera. “Angelita” es el nombre étnico de la abeja sin aguijón Tetragonisca angustula en Ecuador y en otros países latinoamericanos. A fin de singularizar las mieles de T. angustula, se realizó su caracterización físicoquímica según los métodos clásicos de indicadores de calidad en las normas para miel de abejas. El contenido de nitrógeno se determinó por microKjeldahl. Son mieles claras de color ámbar entre 75 y 102 unidades Pfund. La composición físicoquímica varió así: acidez libre 22,50 – 25,20 meq/kg, azúcares reductores 56,43 – 63,83 g/ 100g, cenizas 0,50 – 0,16 g /100 g, color 75 – 102 unidades Pfund, hidroximetilfurfural 0,44 – 1,41 mg/kg, humedad 23,1 – 25,2 g/100 g, nitrógeno 33,66 – 85,78 mg/100 g, pH 3,66 – 4,22, sacarosa aparente 1,46 – 2,36 g/100 g y sólidos insolubles en agua 0,03 – 0,07 g/100g. ABSTRACTIn Ecuador the mega-biodiversity is also present in the honey produced in cerumen pots, which are not included in the technical quality norms of the Ecuadorian Institute of Norms NET INEN 1572. The honey norms only refer to the honey produced by the comercial honey bee Apis mellifera. “Angelita” is the ethnic name of the stingless honey bee Tetragonisca angustula in Ecuador and in other Latin-American countries. In order to single out the honey of T. angustula, its physicochemical characterization was carried out according to conventional methods of quality indicators in standards for honey. The nitrogen content was determined by microKjeldahl. These are clear amber color honeys from 75 to 102 Pfund units. The physicochemical composition varied as follows: free acidity 22.50 – 25.20 meq/kg, reducing sugars 56.43 – 63.83 g/ 100g, ash 0.50 – 0.16 g /100 g, color 75 – 102 Pfund units, hydroximethylfurfural 0.44 – 1.41 mg/kg, moisture 23.1 – 25.2 g/100 g, nitrogen 33.66 – 85.78 mg/100 g, pH 3.66 – 4.22, apparent sucrose 1.46 – 2.36 g/100 g and water insoluble solids 0.03 – 0.07 g/100g.
