The invention discloses a novel aluminum-free, quick and safe special composite fried bread stick leavening agent which consists of the following raw materials in percentage by weight: 12%-18% of ammonium hydrogen carbonate, 12%-18% of sodium bicarbonate, 8%-12% of gluconic acid-sigma-lactone, 4%-7% of DL- tartaric acid, 4%-6% of calcium carbonate, 4%-6% of sodium pyrophosphate, 2%-5% of sodium dihydrogen phosphate, 2%-5% of calcium dihydrogen phosphate, 1%-2% of potassium hydrogen tartrate, 0.22%-0.76% of citric acid, 0.22%-0.76% of malic acid, 0.18%-0.56% of glucose oxidase, 0.16%-0.45% of pentosanase, 0.16%-0.25% of fungus alpha-amylase, 0.06%-0.22% of lipase, 10%-18% of salts, 10%-18% of modified starch, wherein the modified starch is one of modified corn starch, modified wheat starch, modified potato starch, modified sweet potato starch and modified cassava starch, wherein the moisture content of the modified starch is lower than 8%, the mass of the modified starch is 1%-3% the total mass of the flour. The special bread stick leavening agent disclosed by the invention can be used for quickly preparing an aluminum-free fried bread stick with a safe and bulk effect through a normal fried bread stick preparation process.
