Do you mean Sodium acid pyrophosphate?

  If that is what you mean, It releases most of the CO2
during the heat of baking. Several types show various rates of
reaction. These differ in terms of processing, porosity and
granulation, but they are chemically the same. Typically SAPP releases
from 22% to 40% of the gas in the first two minutes of mixing, little
or none during holding, and the balance during baking. High levels can
promote a slightly bitter aftertaste in the finished product. SAPPs
often are used in cake doughnuts and refrigerated and frozen doughs

Each acid produces a
slightly different texture. Ions making up the acid salts influence the
crumb structure and texture. Calcium and aluminum ions contribute to a
fine grain and also strengthen the structure of the batter and produce
a spongy texture.
