En Ecuador la megabiodiversidad esta presente tambien en las mieles producidas en potes de cerumen, las cuales no estan incluidas en las normas tecnicas de calidad del Instituto Ecuatoriano de Normalizacion NET INEN 1572. Las normas de miel solo se refieren a la miel producida por la abeja comercial Apis mellifera. “Angelita” es el nombre etnico de la abeja sin aguijon Tetragonisca angustula en Ecuador y en otros paises latinoamericanos. A fin de singularizar las mieles de T. angustula, se realizo su caracterizacion fisicoquimica segun los metodos clasicos de indicadores de calidad en las normas para miel de abejas. El contenido de nitrogeno se determino por microKjeldahl. Son mieles claras de color ambar entre 75 y 102 unidades Pfund. La composicion fisicoquimica vario asi: acidez libre 22,50 – 25,20 meq/kg, azucares 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, nitrogeno 33,66 – 85,78 mg/100 g, pH 3,66 – 4,22, sacarosa aparente 1,46 – 2,36 g/100 g y solidos 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.
