Under nonacidic conditions, it also contributes to the browning of the crust. One important role it plays is to delay starch gelatinisation and protein denaturation temperatures
during cake baking so that the air bubbles can be properly expanded by the carbon dioxide and water vapour before the batter sets (Rosenthal, 1995). As a result, the cake structure is highly
aerated and voluminous (Baeva, Terzieva, & Panchev, 2003).
