Calcium Propionate powder Usage and Synthesis.

Calcium propionate is the normal intermediate product of animal body metabolism, it is safer for animals to feed on. It has a wide range of antimicrobial effect on mold, enzyme bacteria and bacteria, inhibit microbial reproduction, can prevent moldy feed, can be used as food and feed mold inhibitor and bread and pastry preservation agent.

As a feed additive, it can effectively inhibit moldy feed and prolong the preservation period of feed, and if it is used with other inorganic salts, it can also improve the appetite of livestock and milk production of cows, and its additive amount is less than 0.3% of the compound feed (in terms of propionic acid).

China's regulations as a food additive, according to GB2760-86 implementation, the scope of its use only bread, vinegar, soy sauce, soy products, the maximum use of 2.5g/kg.

Uses of Calcium Propionate powder.

Calcium propionate is also an acidic food preservative, and its bacteriostatic effect is affected by the environmental Ph value. The minimum inhibitory concentration is 0.01% at Ph 5.0 and 0.5% at Ph 6.5. It has strong inhibitory effect on various types of molds, gram-negative bacilli or aerobic bacilli in acidic medium.

It is effective in preventing the production of aflatoxin, while it is almost ineffective against yeast. In the food industry, it is mainly used in vinegar, soy sauce, bread, pastry and soybean products, the maximum use (propionic acid, the same below) 2.5g/kg; in the raw noodles and wet products, the maximum use of 0.25g/kg. it can also be used as feed mold inhibitor.

It can be used as preservative of bread, pastry and cheese, and antifungal agent of feed. As a food preservative, propionate and calcium propionate are mainly used in bread because sodium propionate raises the ph value of bread and delays the fermentation of raw noodles; sodium propionate is mostly used in pastries because synthetic bulking agents are used to bulking up pastries, and there is no problem with the development of yeast caused by the rise in pH value. When used as a feed preservative, sodium propionate is better than calcium propionate. However, calcium propionate is more stable than sodium propionate.

Propionate in food in addition to bread, pastries, cheese, etc., can also be used for soy sauce mold, inhibit re-fermentation effect. In medicine, propionate can be made into bulk, solution and ointment to treat diseases caused by skin parasitic mold. The ointment (liquid) contains 12.3% sodium propionate and the bulk contains 15% calcium propionate.

Preparation of Calcium Propionate powder.

First of all, the raw material calcium carbonate made of water suspension, the water should be refined and purified to remove impurities such as heavy metals and magnesium. CaCO3 water suspension quantitatively into the neutralization kettle, keep the kettle temperature of 60 ~ 80 ℃, while stirring while adding propionic acid, neutralization reaction lasted 2 ~ 3 hours, at this time there is a large amount of CO2 gas escapes, can be discharged through the condenser vent pipe.

By adjusting the external heating temperature, adding acid and stirring speed to achieve the best reaction conditions, the end point of the reaction pH value should be controlled at 7 ~ 8, the reaction is reversible, the CO2 gas should be discharged in time to better control the end point of the reaction.

After neutralization of the aqueous solution through vacuum filtration, the filtrate in the evaporation kettle concentration, and then put into the crystallization tank at room temperature and pressure at room temperature and pressure slowly cooling crystallization. The mother liquor can be returned to the evaporation kettle set for 2 to 3 times and then discarded. The separated solid is dried into small particles and crushed, measured and packaged to obtain calcium propionate finished product.

Product method of Bulk Calcium Propionate powder.

Produced by propionic acid and calcium hydroxide or calcium carbonate reaction: industry generally use calcium hydroxide as raw material, in the reaction pot will be adjusted to calcium hydroxide suspension, add propionic acid, the reaction temperature is maintained at 70-100 ℃, the reaction 2-3 hours, the end of the reaction pH control in 7-8, the reaction material filtration, drying that is the finished product.
