Abstract
A new leavening acid composition is provided comprising a potassium modified 1:3:8 sodium aluminum phosphate, the calcium modified derivatives or mixtures thereof in combination with an alkali metal acid pyrophosphate such as sodium acid pyrophosphate. The leavening action of the combination in biscuits using a slow sodium acid pyrophosphate is slower than the action of either ingredient alone. The compositions are useful in leavening baked goods and especially refrigerated canned biscuits.
Claims11
A leavening acid composition for biscuits comprising:
- (a) a sodium aluminum phosphate derivative selected from the group consisting of a potassium modified 1:3:8 sodium aluminum phosphate, the calcium modified derivatives thereof prepared by contacting a slurry of said potassium modified sodium aluminum phosphate with a calcium compound followed by granulating the product while drying and mixtures thereof;
- in combination with
- (b) a slow alkali metal acid pyrophosphate having a doughnut dough rate of reaction of less than 30% CO.sub.2 evolved after two minutes and less than 35% evolved CO.sub.2 after ten minutes at 27.degree. C.
A leavening acid composition comprising:
- (a) a calcium modified derivative of a potassium modified sodium aluminum phosphte of the approximate formula:
- Na.sub.(b) K.sub.(b) Al.sub.3 H.sub.14 (PO.sub.4).sub.8.4H.sub.2 O
- wherein (a) and (b) are numbers and the additive total of (a) and (b) is a number within the range of from about 0.92 to about 1.08;
- in combination with
- (b) a fast alkali metal acid pyrophosphate having a doughnut dough rate of reaction greater than 34% evolved CO.sub.2 after two minutes and greater than 40% evolved CO.sub.2 after ten minutes at 27.degree. C.
