  • Calcium Propionate FAQ

    Q1: Is calcium propionate dangerous to the human body?
    A1: Is calcium propionate bad for you? When used within safe limits, it is harmless and can even supplement calcium. Excessive intake can irritate the digestive tract and stomach lining. Children and pregnant women should avoid it as much as possible.
     
    Q2: Is calcium propionate a natural preservative?
    A2: Calcium propionate is mainly made by neutralizing natural propionic acid and calcium salts, and is a synthetic food preservative. However, small amounts of natural components may be found in Swiss cheese.

    Q3: Is calcium propionate halal?
    A3: Is calcium propionate vegan? Calcium propionate does not involve any animal ingredients in its production process and is a safe and clean food-grade preservative for halal and vegan use. Customers should consider whether other ingredients are halal and vegan when purchasing.

    Q4: Does Calcium Propionate Contain Iodine?
    A4: Calcium propionate, with the molecular formula Ca(C₂H₅COO)₂, does not contain iodine but provides the essential calcium for the human body.

    Q5: Where Can I Buy Calcium Propionate?
    A5: Polifar --- Calcium Propionate Distributor, providing long-term wholesale services. Polifar offer a one-stop purchasing solution, helping you obtain satisfactory products worry-free, conveniently, and quickly!
     
     


  • Packaging and storage

    Most pre-mixed packaging bags use three-in-one paper bags, which have the advantages of waterproof, light-proof, no leakage and not easy to damage. Generally 20-25 kg/bag. Since the premix contains a variety of active micro-components, the chance of their interaction will increase, so care should be taken to prevent moisture during storage.
     
  • Measurement and mixing

    For the measurement of micro-components, electronic scales should be used, accurate to 0.01 grams, and large amounts of raw materials can be used on scales. There are many kinds of mixers. Ordinary vertical mixers are prone to shortcomings such as automatic separation and slow discharge speed due to their slow feeding speed. It is best to use a horizontal double ribbon mixer or a cone mixer.
  • Amino acid addition problem

    Many experiments have confirmed that adding rumen bypass methionine and lysine can increase milk production and economic benefits. This can be added by dairy farms according to specific conditions.
  • Stability of trace components

    Under normal storage and use conditions, the physical and chemical properties of trace elements, vitamins and other components in the premix are stable, but when the moisture content is high, the stability is poor and the loss rate is large. Strictly control the water content of the premix, preferably not more than 5%.

Product performance:

As amino acid for forge, threonine is widely added in the forage for newborn pig, covering pig, poultry, shrimp, eel and so. It can:

1. Keep the balance of amino acids in the forage and stimulate the growth of the animals;

2. Improve the meat quality;

3. Increase the nutritive value of forage raw materials which have low amino acid digestibility;

4. Apply to the production low-protein forage;

5. Cut down the cost of raw materials for forage;

6. Decrease the nitrogen content in the excrement and urine of animals so that the release of ammonia is slowed and the ammonia concentration is kept low in animal shed.            Meihua, Eppen, FUFENG, JINXIANG

Q1: What is feed grade L-threonine?

A1: Feed grade L-threonine is a specific form of the essential amino acid L-threonine that is produced and formulated for use as an additive in animal feed. L-threonine is categorized as an essential amino acid because animals cannot synthesize it in sufficient quantities and must obtain it from their diet. Feed grade L-threonine is typically manufactured through fermentation or chemical synthesis processes to ensure its purity and quality meet the requirements for animal nutrition. It is commonly used in animal feed formulations to supplement and balance the amino acid profile, particularly in diets where the natural sources of L-threonine may be inadequate to meet the animals' requirements for growth, development, and overall health.


Q2: What is the difference between feed grade L-threonine and L-arginine?

A2: Feed grade L-threonine and L-arginine are both essential amino acids used in animal nutrition, but they serve different functions in the body and have distinct characteristics. L-threonine is primarily involved in protein synthesis, immune function, and intestinal health, while L-arginine plays roles in protein metabolism, immune response, hormone secretion, and blood vessel dilation. Additionally, L-threonine has a hydroxyl group (-OH) attached to its side chain, whereas L-arginine contains a guanidino group (-NH-C(NH2)(NH2)) in its side chain. While both amino acids are important for animal health and growth, they are sourced differently and have specific applications in animal feed formulations.
