Sodium aluminum phosphate

Table 6 Hsts the leavening acids and the corresponding rates of reaction. The leavening acids most frequently used iaclude potassium acid tartrate, sodium aluminum sulfate, 5-gluconolactone, and ortho- and pyrophosphates. The phosphates iaclude calcium phosphate [7758-23-8] CaHPO, sodium aluminum phosphate, and sodium acid pyrophosphate (66).

A number of acidic phosphates which vary in their rate of reaction are available for use in a wide variety of bakery appHcations. These acids, which include monocalcium phosphate, sodium aluminum phosphate, and sodium acid pyrophosphate, release carbon dioxide at a controlled rate to give a certain fraction prior to baking the remaining fraction is released at a specific time during baking. Controlled releasing of carbon dioxide at the time it is needed can also be achieved by a mixture of different types of leavening acids. 

DKP = dipotassium phosphate Poly = polyphosphate and SALP = sodium aluminum phosphate. Other terms may be found in the text.

For pancake and waffle mixes, a common blend of leavening acids is 20-5097 monnealcium phosphate monohydrate or monocalcium phosphatc lanhydrousi. combined with 70-81)97 sodium aluminum phosphate A hatter of this type can he prepared several hours in advance if retained under refrigeration It lias been observed that such u batter will sour before a serious loss ol leavening power occurs. 

Prepared bi.scitil mixes made of flour, shortening, and salt usually contain 50-5057 lnnnncaleium phosphate I anhydrous) and 50-71)97 sodium aluminum phusphale or sodium acid pyrophosphate. Sell-rising flours and corn meals usually contain flour or com meal, salt, soda, and leavening acid. Usually used in these products are combinations of sodium aluminum phosphate and monncalciuin phosphate (anhydrous).

Endocrine Effects. Little is known about the effects of aluminum on endocrine systems. The oral administration of sodium aluminum phosphate to male and female Beagle dogs for 6 months did not alter thyroid, adrenal, or pituitary gland weight or microanatomy (Katz et al. 1984 Pettersen et al. 1990). These organs were also normal in male and female Wistar rats fed a diet containing unspecified amounts of aluminum phosphide/ammonium carbamate for 24 months (Hackenberg 1972).
