Propionate formula Propionate Chemical Properties,Uses,Production Food antifungal agent Calcium Propionate as the newer food antifungal agent, is the calcium salt of propanoic acid which is a antifungal agent. It appears as white crystalline or powder, odorless or having slight specific odor of propionic acid, stable under light and heathygroscopic, soluble in water while aqueous solution is alkaline, slightly propiojate in methanol and ethanol, not soluble ciclo stanozolol rwr feminino benzene and acetone. Under acidic propionate formula, it generates free propanoic acid which is weaker than sorbic acid while stronger than acetic acid, and propionate formula an antibacterial effect on Aspergillus niger and gas bacillus rather than yeast. Calcium Propionate is a normal intermediate product of animal metabolism and is safe eaten by animals.

    Properties Safety Price 7 Uses Suppliers Calcium Propionate Properties Melting point: Incompatible with strong oxidizing agents. Calcium Propionate Chemical Properties,Uses,Production Food antifungal agent Calcium Propionate as the newer food antifungal agent, is the calcium salt of propanoic acid which is a antifungal agent.

    It appears as white crystalline or powder, odorless or having slight specific odor of propionic acid, stable under light and heat , hygroscopic, soluble in water while aqueous solution is alkaline, slightly soluble in methanol and ethanol, not soluble in benzene and acetone.

    Under acidic conditions, it generates free propanoic acid which is weaker than sorbic acid while stronger than acetic acid, and has an antibacterial effect on Aspergillus niger and gas bacillus rather than yeast. Calcium Propionate is a normal intermediate product of animal metabolism and is safe eaten by animals. It has a broad antibacterial activity to mold bacteria and yeast bacteria, inhibiting the propagation of microorganisms, preventing feed molding, which can be used as a fungicide on food and feed and a preservative for bread and pastries.

    As a feed additive ,it can effectively prevent feed molding and prolong shelf life of feed. If combined with other inorganic complexes, it can also improve the appetite of livestock, increase milk production in cows, and its dosage is less than 0.

    China provides when it is used as a food additive, according to GB execution, it can be added to bread, vinegar, soy sauce, soy products, and the maximum use is 2. Production Method First, the raw material calcium carbonate is made into aqueous suspension, the water needs to be refined and purified to remove heavy metals magnesium and other impurities.

    Adjusting the heating temperature outside, adding acid and stirring rate can help the reaction to achieve the best conditions , the reaction should be controlled in the final pH of 7 to 8, this reaction is reversible, which means CO2 gas should be promptly discharged to control the end point of the reaction better.

    The neutralized aqueous solution is filtrated through vacuum , concentrated in an evaporator vessel, and then placed in a crystallizer tank at normal temperature and pressure to cool slowly into crystallization.

    The mother liquor can be returned to the evaporator vessel to apply 2 or 3 times and then can be discarded. Dry the separated solids into small particles and after crushing, metering and packaging , Calcium Propionate products are obtained. The above information is edited by the Chemicalbook of Tian Ye. Japan use propionic acid to count: It is mainly used for bread and pastry. The excess of amount will prevent the growth of yeast in the bread, which damages the flavor.

    It can be used to prevent growth of Aspergillus niger Asp. Niger , aerobic spore-forming bacteria B. Calcium salt is generally used in bread while sodium salt is used in West Point. Alkalinity resulting from the use of sodium causes the delaying of the dough fermentation but use of calcium can strengthen the role of calcium. If calcium salt is used in West Point, then it can react to the sodium bicarbonate in the leavening agent, producing insoluble calcium carbonate, which reduces the amount of CO2 generated,so sodium salt is mainly used.

    Chemical Properties White crystalline powder or granules. Odorless and minor irritation. Uses Reagents for the analysis. Calcium Propionate is an acid-type food preservative, with its inhibitory effected by the environmental pH.

    In the acidic medium ,it has a strong inhibitory effect on the various types of fungi, aerobic bacillus or gram-negative bacilli.

    It has a specific effect on preventing the production of Aflatoxin streptozotocin, but has little effect on the yeast. In the food industry, it is mainly used in vinegar, soy sauce, bread, cakes and soy products,whose maximum usage use propionic acid to count, the same below is 2.

    Also ,it can be used for feed antifungal agent. It is used for breads, pastries and cheese preservatives and feed fungicide. Calcium Propionate as a food preservative, calcium propionate is mainly used for bread, because sodium propionate keeps pH of bread rising, delays the fermentation of the dough; sodium propionate is more widely used for cake, because the pastry gets bulky by using leavening agent, there is no problem about yeast development caused by tincrease in the pH.

    As a feed preservative, sodium propionate is better than calcium propionate. But Calcium Propionate is more stable than sodium propionate. In food industry , except uses for bread, pastries, cheese, Calcium Propionate can also be used for preventing soy sauce from getting moldy which inhibits the refermentation.

    In medicine, Calcium Propionate can be made into powders, solutions and ointments to treat skin disease caused by parasitic fungi. Ointment liquid contains Production method By reacting propanoic acid with calcium hydroxide or calcium carbonate: The product is obtained after filtering and drying the reaction mass.

    Propionic acid neutralizes calcium hydroxide. Neutralization fluid is filtered to remove insoluble material. The supernatant is concentrated, cooled and crystallized,separated, dried to obtain products. Chemical Properties white powder Uses As an inhibitor of molds and other microorganisms in foods, tobacco, pharmaceuticals; in butyl rubber to improve processability and scorching resistance.

    Storage Characteristics Ventilated, low-temperature ,dry storeroom. No account, fast registration. Jiangsu Kolod Food Ingredients Co. Henan Tianfu Chemical Co. Meryer Shanghai Chemical Technology Co.
