What is Calcium Propionate?

Calcium propionate is a secure and trustworthy antifungal representative for food and also feed approved by the Globe Health Company (WHO) and the United Nations Food as well as Farming Organization (FAO). Calcium propionate, like various other fats, can be soaked up by human beings and pets with metabolic process and supply the essential calcium for human beings as well as pets. This advantage is unmatched by other antifungal agents as well as is considered GRAS. The calcium propionate created by our firm uses high-purity imported propionic acid and ion-exchange membrane fluid caustic soda as basic materials, and the high quality is steady. Its antibacterial impact is influenced by the pH worth of the setting. The mold inhibitory result is the most effective when the pH value is 5.0; the anti-bacterial capacity is considerably decreased when the pH worth is 6.0, and also the minimal inhibitory concentration is 0.01%.

Calcium Propionate Uses

  1. Calcium propionate can be utilized as a chemical in solid foods such as bread, bread, cheese, etc, as an antifungal agent as well as mineral additive in the feed industry.
  2. Calcium propionate liquid damp acid chemical, its antibacterial result is influenced by the pH of the setting. The minimum inhibitory focus is 0.01% at pH 5.0 and 0.5% at pH 6.5. It has a solid inhibitory result on numerous mold and mildews, cardiovascular bacillus or gram-negative bacillus in acidic medium. It has a special result on protecting against the manufacturing of aflatoxin, however it is nearly ineffective on yeast. Furthermore, it is also utilized as a food chemical.
  3. Calcium propionate is utilized as a food antibacterial and also antifungal representative, as well as has a wide range of repressive results on mold and mildew, yeast and also microorganisms.
  4. When calcium propionate is used as a feed chemical, the impact of salt propionate is much better than that of calcium propionate. However calcium propionate is more steady than salt propionate. Propionate is not only made use of in bread, pastry, cheese, and so on in food, however also made use of in soy sauce to prevent mold and hinder re-fermentation. In medicine, propionate can be made into powder, option and ointment to deal with diseases brought on by skin parasitical molds. The ointment (liquid) consists of 12.3% salt propionate, and also the powder has 15% calcium propionate.

Preparation of Calcium Propionate

Method 1: A process with a production capacity of 600t/a that is neutralized by propionic acid and calcium carbonate or calcium hydroxide. The reaction of propionic acid with calcium carbonate is completely similar to that of propionic acid with sodium carbonate. The reaction of propionic acid with calcium hydroxide and its production process are shown in the figure:

The main raw materials are propionic acid (food grade, content above 99.5%), quicklime (industrial grade, content of calcium chloride above 95%), deionized water (arsenic and heavy metals in the water must not be detected). Neutralization reaction conditions: the reaction temperature is 70-90°C, the reaction time is about 2-3 hours, and the pH value at the end of the reaction is 7-8. Concentration and crystallization process conditions The heat transfer oil inlet temperature is 170-180°C, the outlet temperature is 120-130°C, and the heat transfer oil flow rate is 6m3/h. Airflow drying process conditions The hot air temperature is 200°C, the drying temperature is 120-130°C, the material outlet temperature is 60°C, and the wind pressure is 4-5kPa.

Method 2: A membrane chemical reactor is used to prepare a high-purity calcium propionate. The preparation process roughly includes the following steps: (1) Put a certain amount of deionized water into the above membrane chemical reactor, and then heat it at 50-80°C At this time, the input amount of solid calcium hydroxide and propionic acid is alternately input into the membrane chemical reactor in 4-10 batches according to the mass ratio of 1:3.5-3.7, that is, a batch of propionic acid is added and then a batch of calcium hydroxide is added. , during the process of putting in the last batch of calcium hydroxide, test the pH value of the neutralizing solution several times, control the feeding speed and amount of the remaining calcium hydroxide according to the pH value, and stop feeding when the pH value reaches 6.4-8.0; (2 ) After feeding, keep the above reaction solution at 70-80°C for 30-40 minutes, and control the pH value of the reaction solution to 6.4-8.0; (3) After the reaction in the membrane chemical reactor, press filter, Crystallization, dehydration, and drying processes to obtain calcium propionate powder.

Calcium Propionate Usage Limit

GB2760-96 (g/kg): Bread, vinegar, soy sauce, soybean food, cakes, 2.5; raw noodle damp items (referring to chopped noodle, wonton skin) ≤ 0.25 (determined by propionic acid).
FAO/WHO (1984 ): Refined cheese 3000mg/kg (used alone or in combination with propionic acid, sorbic acid as well as their salts).
Japan (computed as propionic acid): 2.5 g/kg (3.15 g of this product). Mostly made use of for bread and also pastries. 1.0 g of calcium salt (monohydrate salt) is equivalent to 0.790 g of propionic acid. Utilizing excessive will certainly stop the development of baker’s yeast as well as impair flavor. It can stop the growth of Aspergillus niger (Asp. Niger) and cardio spore-forming bacteria (B. Subtilis).
USDA, 9CFR, § 318.7( 2000 ): Flour products, 0.32% (based upon the amount of wheat flour, used alone or in mix with salt propionate).
USDA § 381.147 (1994 ): 3% of new pie dough (based upon the quantity of wheat flour).
Calcium salts are generally used in bread, as well as sodium salts are made use of in pastries. The alkalinity caused by making use of salt salts will certainly postpone the fermentation of dough, while the use of calcium salts has the result of enhancing calcium. If calcium salt is made use of in West Factor, it will certainly react with sodium bicarbonate in the raising agent to generate insoluble calcium carbonate, decreasing the amount of CO2 created, so sodium salt is mostly utilized.
