When selecting ferric pyrophosphate raw materials with high cost-effectiveness, the following aspects can be considered:

I. Pay attention to product quality

Content of active ingredients: High-quality ferric pyrophosphate raw materials usually have a relatively high iron content, generally around 24% - 30%. It is advisable to choose products with an active substance content of approximately 99%.

Purity and impurity content: Ferric pyrophosphate with high purity has a low impurity content. The content of arsenic (calculated as As) should not exceed 0.0003%, and the content of heavy metals (calculated as Pb) should not exceed 0.002%.

Appearance and properties: Normal ferric pyrophosphate is a white or yellowish-white powder, odorless, with a slight iron smell. If there are obvious color abnormalities, caking, or peculiar smells, the quality may be poor.

II. Consider price factors

Compare different suppliers: Use platforms such as Alibaba and Food Business Network to find several suppliers and compare their prices.

Pay attention to the purchase quantity: Generally, the larger the purchase quantity, the lower the unit price. If the usage quantity is large, you can negotiate more favorable prices with the suppliers or strive for additional services.

III. Evaluate the reputation of suppliers

Qualification certification: Select suppliers with relevant production licenses and qualification certifications, such as food additive production licenses.

Market reputation: Consult peers or other enterprises that have used this raw material to learn about the reputation of the suppliers and the quality of their products. You can also check the evaluations of the suppliers on e-commerce platforms.

After-sales service: Good suppliers can provide timely after-sales service. For example, if problems arise during the use of the products, they can provide technical support and solutions.

IV. Consider application requirements

Application fields: Select according to your own needs. Ferric pyrophosphate used for food fortification should meet food-grade standards; for other industrial fields, it needs to meet the corresponding industry standards.

Solubility and stability: If it is used for liquid products, choose ferric pyrophosphate with good solubility; if the product needs to be processed at high temperatures or stored for a long time, choose ferric pyrophosphate with good stability and resistance to oxidation.
