Résumé : |
At the University of Naples Federico II scientists tested a new foaming method on a special thermosetting polymer : pizza dough. This is a very complex viscoelastic heterogeneous polymeric mixture that forms bubbles in several hours thanks to the presence of the biochemical blowing agent yeast. The dough cures in the oven at 300 to 400 °C in a few tens of seconds. Possibility to concomitantly foam and bake, reducing the overall timing, is explored through comparison with the much faster polyurethane foaming. |
