Eurofins Microbiology Laboratories has investigated the ability of Saftea® Urn Liners to inhibit growth of bacteria, yeast, and mold in a brewed tea product in commercial urns held under typical room-temperature commercial storage conditions. As compared to an urn containing either a similar competitor liner product, or an urn using no liner at all, the tea contained in the urn using the Saftea® Urn Liner was better able to resist the outgrowth of bacteria, yeasts, and molds, especially over extended storage periods. The effect against fungal organisms (yeasts and molds) was most significant, with levels of these organisms recovered at 10-100 times less over the course of the study in the Saftea® Urn Liner-lined urn than the competitor-lined urn or the urn with no liner. This means that the use of a Saftea® Urn Liner, as opposed to either the lack of a liner or the use of a competitor liner, may increase both the shelf life and the overall safety of brewed tea held in these urns over extended storage times.
