Calcium Propionate Powder - Food Grade Preservative Supplier

Shaanxi Nuoyuan Biotech Co., Ltd. delivers Calcium Propionate Powder at 99% purity, produced by our 30000㎡ accredited factory with 20000 tonnes yearly capacity. Our food-grade preservative E282 efficiently prevents the formation of mould and bacteria and maintains the activity of yeast, a need for industrial bakery operations.

5 sophisticated HPLC testing equipment ensure that every batch made is being continuously quality checked to fulfil FCC and E282 requirements. Our product has excellent water solubility (40g/100ml at 20°C) and excellent heat stability under baking conditions. Every batch is rigorously tested for heavy metals (Lead ≤2mg/kg, Arsenic ≤3mg/kg) and has less than 4.0 % moisture content. We have a ready supply to send fast to our clients in North America, Europe and worldwide markets.

What is Calcium Propionate Powder?

It is the calcium salt of propionic acid, known generally as E282, a non-toxic organic preservative that is of fundamental importance to the food and feed sectors.

This crystalline white chemical acts by disturbing microbial metabolism. It is very effective in preventing the growth of moulds and rope bacteria (Bacillus mesentericus) without any interference with the yeast fermentation. This makes it ideal for your bread and pastry manufacturing lines.

It is most effective when used in acidic conditions, i.e. below pH 5.5. It also provides a readily accessible supply of calcium and so boosts the nutritional value of your recipes. The FDA deems it GRAS ( Generally Recognised as Safe ) and your body treats it as it does other common fatty acids .

The solution tackles three major concerns for producers that have spoiling issues with high moisture products. They are: 1. Bakery items that expire quickly 2. Storage of feed that goes bad 3. Shelf stability without changing the flavour or the texture.

Industrial Applications & Key Benefits

Bakery & Cereal Products

In large-scale bread manufacturing, add 0.2-0.5% product directly into your dough formulation. It prevents mold and rope bacteria even in tropical high-humidity climates where traditional preservatives fail.

Keeps your tortillas, breads and pastries fresh longer. The chemical does not affect yeast activity therefore fermentation is normal and shelf life is extended by 5-10 days.

Animal Feed and Nutrition

Our product is used by Feed Manufacturers to avoid aerobic spoiling of silage and concentrated feeds. It inhibits mycotoxin production – safeguarding animal health and milk production.

The calcium part is two-fold, as a nutritional supplement and as a preservative. Your formulations are in compliance with safety and nutrition regulations at the same time.

Dairy & Processed Food

Cheesemakers use it to prevent mould on surfaces. Jam makers improve shelf life without altering sweetness characteristics. In processed meats it suppresses bacterial development during distribution.

The compound remains stable through heat processing, pasteurization, and sterilization cycles. That thermal stability gives you consistent results across various production conditions.

Manufacturing Process & Quality Assurance

Our production uses controlled neutralization of propionic acid with pharmaceutical-grade calcium hydroxide. The reaction occurs at 70-100°C with precise pH monitoring between 7.0-8.0 over 2-3 hours.

After synthesis we filter solution via many steps for the removal of insoluble contaminants. The concentration and crystallisation are performed under vacuum conditions. Crystals are separated by centrifugation and the final white powder is produced by spray-drying, controlling the particle size distribution.

Each batch is tested by microbiological screening for Salmonella and E. coli. We do heavy metal analysis using ICP-MS and we check the bulk density to ensure your automated mixing systems don't become clogged.

We have very stringent documentation during manufacturing. Traceability assures compliance with international food safety standards from the procurement of raw materials to the final packaging.

Characteristics of Industrial Use Property

It has the usual little smell of propionic acid that is hardly perceptible in the completed product. It is highly soluble in water, which permits facile inclusion into aqueous systems and dough matrices.

The chemical is very heat stable in comparison with sorbates. Potassium sorbate breaks down at temperatures above 180°C, although our product is OK up to typical baking temperatures (200-250°C).

pH-dependent action indicates best antibacterial efficacy in slightly acidic formulations. The advantages of calcium fortification are maintained, but the efficacy is reduced under neutral pH conditions.

Particle size distribution (95% to 80 mesh) allows for consistent dispersion in dry mixtures. Controlled bulk density (0.55-0.65 g/cm3) enables dust problems in manufacturing facilities, but achieves flowability by use of automated dosing equipment.

Certifications & Compliance Standards

Frequently Asked Questions

Q: What is the minimum order amount?

A: We are glad to accept sample orders from 100g. Commercial orders start from 25kg with ready stock for fast dispatch.

Q: How long does Calcium Propionate last in baked goods?

A: When applied at a concentration of 0.2-0.5%, it enhances the mold-free shelf life by 5-10 days compared to unpreserved items, depending on storage circumstances.

Q: Is it an effect on yeast fermentation in making bread?

A: No. There are some preservatives that have a huge effect on the yeast and prevent it from doing its job of fermenting and rising.

Q: Can I use this in organic certified products?

A: Rules differ from area to area. It is normally banned in USDA Organic goods in the U.S., but allowed in regular foods. Check local organic requirements.

Q: What is the wait time for large orders?

A: We ship in-stock merchandise within 3-5 business days. Custom specs may take 15-20 days manufacture time.

Q: How do I store it to maximise shelf life?

A: Store in cool, dry conditions below 25°C in sealed containers. Proper storage extends its quality for 24 months from the date of manufacture.
