There is an optimal rate for the pressure decrease: if the rate is too low, the dough collapses before baking; conversely, if it is too high, the baked dough ruptures due to the force exerted by the gas attempting to escape. Furthermore, the specific way in which pressure is applied causes coalescence to occur within the dough as it bakes.<\/p>\n\n\n\n<p>Based on these findings, a pressure vessel was designed, capable of baking a 28 cm pizza without the use of yeast. However, further research is required to better define the relationships between these variables and to refine the process.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Bibliographic references<\/strong>: E.
