Abstract
The invention discloses a production method of acid calcium pyrophosphate for food leavening agent. The production method comprises the following steps: carrying out neutralization by taking phosphoric acid and lime milk, or phosphoric acid and limestone as raw materials so as to obtain a monocalcium phosphate solution; drying the monocalcium phosphate solution by a spray drying tower and polymerizing by a polymerization furnace so as to form the acid calcium pyrophosphate which is used as a food leavening agent. With the production method of the acid calcium pyrophosphate for the food leavening agent, the problem of excessive sodium in the application process of the acid calcium pyrophosphate is solved, and the acid calcium pyrophosphate has a special effect of calcium supplement, so that the acid calcium pyrophosphate can replace the acid sodium pyrophosphate in the baking field. The production technology provided by the invention is strong in operability, the technological process is very convenient for industrialization, and the produced products are high in purity.
Description
Technical field
The production method of a kind of acid Calcium Pyrophosphate for food expander of the present invention.
Background technology
Raising agent is a kind of foodstuff additive commonly used in the foodstuffs industry, can emit great amount of carbon dioxide gas owing to it is heated with alkali substance reaction, thereby be widely used in the making processes of bread, cake, deep-fried twisted dough sticks, steamed bun etc.
The tradition raising agent is sodium acid pyrophosphate and acidic aluminium phosphate sodium etc., mainly is comprised of sodium, aluminium and phosphoric.Wherein the use of acidic aluminium phosphate sodium in deep-fried twisted dough sticks has history for many years, and along with going deep into of research, the unfavorable factor of aluminium salt pair human body makes it to use and is restricted.What application was more at present is sodium salt, but sodium element comes to be absorbed by the body after excessive, can surpass the scope that kidney can bear, and blood will be detained moisture, force heart working intensity to increase, cause hypertension, kidney disease, cardiovascular and cerebrovascular diseases, diabetes etc.So how to substitute sodium acid pyrophosphate with a kind of safer, more healthy raw material raising agent, solve the problem of " sodium exceeds standard " in the national diet system, become the later development trend of food baking industry.Acid Calcium Pyrophosphate (Calcium Acid Pyrophosphate is hereinafter to be referred as CAPP) is a kind of New Phosphorus hydrochlorate, at present the domestic relevant report that does not have its production technique.
Summary of the invention
The invention provides a kind of production method of the acid Calcium Pyrophosphate for food expander, do not contain sodium element in the food expander structure of the method gained, solved the puzzlement that sodium element brings, can also play the special-effect of replenishing the calcium.
Above-mentioned purpose of the present invention is to realize by such technical scheme: a kind of production method of the acid Calcium Pyrophosphate for food expander, take phosphoric acid and milk of lime or phosphoric acid and Wingdale breast as raw material, carry out neutralization reaction, obtain the biphosphate calcium solution, dry, the polymerization furnace polymerization of the spray-dried tower of described biphosphate calcium solution, make the acid Calcium Pyrophosphate, described acid Calcium Pyrophosphate is used for food expander.
It is 0.48-0.50 that the input ratio of raw material phosphoric acid and milk of lime or Wingdale breast is controlled at Ca:P.
The temperature of neutralization reaction is controlled at 60-80 ° of C, reaction times 1-1.5h.
The spray-drying tower inlet temperature is at 450-650 ° of C, and temperature out is at 90-140 ° of C.
The polymerization furnace polymerization temperature is at 240-300 ° of C, and steam partial pressure is at 4.5-6.5Mpa, reaction times 2-3h.
The production method of a kind of acid Calcium Pyrophosphate for food expander of the present invention has solved the problem of " sodium exceeds standard " in the sodium acid pyrophosphate application process, can also play the special-effect of replenishing the calcium simultaneously, can the replacing acid sodium acid pyrophosphate in the field of curing.Production technique provided by the invention is workable, and flow process extremely is convenient to industrialization, and the purity of products obtained therefrom is high.
