Propolis extract significantly reduces microbial load in fresh bee pollen for human consumption = El extracto de propóleos reduce significativamente la carga microbiana en el polen apícola fresco para consumo humano

We evaluated propolis as a preservative of fresh bee pollen for human consumption. An in vitro quantitative assay was performed to determine the antimicrobial activity of a propolis ethanolic extract against cultivable heterotrophic mesophilic bacteria, molds and yeasts in bee pollen for 22 days.

Summary:We evaluated propolis as a preservative of fresh bee pollen for human consumption. An in vitro quantitative assay was performed to determine the antimicrobial activity of a propolis ethanolic extract against cultivable heterotrophic mesophilic bacteria, molds and yeasts in bee pollen for 22 days. The chemical characteristics of the propolis extract were also determined. From the results of the quantitative antimicrobial assay, none of the control treatments exhibited an inhibitory effect similar to that of the ethanolic extract of propolis. This is one of the first studies that combine both bee products, propolis and pollen, to improve the preservation of fresh bee pollen, avoiding the drying process. The results of the in vitro assay were promising, as the antimicrobial action of propolis ethanolic extract against bacteria, molds and yeasts from fresh bee pollen was excellent.
