Pizza

Time was, frozen pizza had a relatively short shelf life due to the breakdown of gluten, a component of pizza dough.  Today's pizzas can be frozen for longer periods due to the addition of gums, protein film formers, and surfactants, which allow the dough to retain its structure during freezing. The resulting combination of puffiness and sturdiness has paved the way for rising crusts, a staple of many popular brands.
