Microbiological quality of honeys marketed in Recife - PE on isotopic evaluation

Resumo

Microbiological analysis and adulterants researches contribute to surveillance of honey: both ensure trade of the products with sanitary and nutritional quality. The main microorganisms identified in honey are fungi and coliforms, and more frequent adulterations by sugars and syrups of the C4 plants, like sugar cane and corn. In this context, the objective of this work was to investigate the microbiological quality of pure and adulterated honeys marketed in Recife - PE, Brazil. In full, 55 honey samples were submitted to isotopic evaluation honey and its protein, and to search of mold and yeasts; coliforms 35°C and 45°C. The results revealed that 31 (56,36%) samples were adulterated with sugars or syrup of the C4 plants and 46 (83,64%) honeys were contaminated with molds and yeasts. Pure and adulterated honeys with sugars or syruos of the C4 plants, contaminated for fungi, were marketed in Recife - PE, Brazil. Its ingestion may harm the consumer when acquire products with microbial contamination.
