Five commercial samples were analyzed, including pH, electrical conductivity, total acidity, color, humidity, ash, heavy metals, trace elements, density, quantification of sugars, polyphenols and corresponding flavonoids for physicochemical properties; In addition, antioxidant properties such as antioxidant capacity and antimicrobial activity using 16 strains ATCC Gram positive, Gram negative, fungi and yeasts; Was evaluated with inhibition halos. The results obtained revealed that all the honey honeys were found within the corresponding parameters of the physical-chemical tests; On the other hand, the honey with code C obtained a high value in the content of polyphenols; In flavonoids bee honeys with code A and B presented higher concentration and in the antioxidant capacity the honey A was highlighted; With regard to heavy metals, all honeys have small concentrations of lead but are not harmful to health, in addition, honey C had favorable results to the concentration of trace elements highlighting the magnesium, finally the antimicrobial activity almost all the honeys had similar results , However, D honey showed less activity against susceptible strains |
