Background

With the development of times and the progress of scientific technology, the work and life rhythm of people is greatly accelerated, the industry of instant food which is suitable for transportation is rapidly developed, particularly, the scale of quick-frozen food is continuously enlarged, the variety is continuously increased, such as quick-frozen steamed bread, steamed stuffed bun and the like, the quick-frozen steamed bread, steamed stuffed bun and the like provide convenient and delicious food for people, particularly office workers, and are generally popular with people.

The leavening agent is a common food additive, is widely applied to quick-frozen wheaten food, enables the food to form a leavened and porous structure in the processing process, has soft and crisp texture, is easy to chew, increases nutrition, is easy to digest and absorb, and presents special flavor, thereby improving the quality of the food. The leavening agent can be directly added into food, and slowly decomposed during dough kneading and heating to generate a large amount of CO₂The gas makes the dough rise and forms a uniform porous tissue structure in the dough, so that the food has the characteristics of crispness or loftiness and softness.

In recent years, aluminum-containing leavening agent is abused in flour products, and the excessive aluminum in food can cause harm to human body, such as toxic action to cranial nerve, influence on memory function in light people, and intelligence decline, brain injury and senile dementia in serious people; aluminum can cause nervous system disorders, leading to a failure in visual and motor coordination; interfering the acid-base balance of the maternal body of the pregnant woman, shrinking the ovary and causing the growth arrest of the fetus; cholestatic liver disease, hypochromic anemia of blood cells; aluminum ions can hinder the absorption of calcium, zinc, iron, magnesium and other elements in a human body, and can easily cause bone softening and fracture; aluminum deposits on the skin and can reduce skin elasticity and increase wrinkles. The aluminum limit in Chinese flour food should be less than or equal to 100 mg/kg.

Therefore, the leavening agent which is free of aluminum and suitable for processing quick-frozen foods is developed to meet the requirement of market development.
