How do you use anti caking agent 341?

Answer 1

All I can tell you is that 341, Is Calcium Phosphate

From wikipedia

Calcium dihydrogen phosphate is also used in the food industry as a leavening agent to cause baked goods to rise. Because it is acidic, when combined with an alkali ingredient - commonly sodium bicarbonate (baking soda) or potassium bicarbonate - it reacts to produce carbon dioxide and a salt. The carbon dioxide gas is what leavens the baked good. When combined in a ready-made baking powder, the acid and alkali ingredients are included in the right proportions such that they will exactly neutralize each other and not significantly affect the overall pH of the product.Apart from acting as leavening agent, it also inhibits microbial activity because of the phosphate ions present in the molecule"
