For food manufacturers, the quality of raw ingredients directly impacts the final product's safety, consistency, and consumer appeal. Corn starch, a fundamental food additive used as a stabilizer, thickener, and filler, is no exception. Sourcing this versatile ingredient requires a keen understanding of its specifications to ensure it meets the stringent demands of food production. If you are looking to buy corn starch, focusing on these key parameters is paramount.

Key Specifications for Corn Starch Procurement

When engaging with a corn starch supplier, particularly those based in China offering competitive pricing for bulk purchases, pay close attention to the following:

• Assay (Purity): The assay percentage indicates the level of pure starch present. For most food applications, a high purity of 99% is desirable to ensure predictable performance and minimize unwanted by-products. This high assay is critical for applications like 'starch jelly' where texture and clarity are paramount.
• CAS Number: The Chemical Abstracts Service (CAS) number uniquely identifies chemical substances. For corn starch, the CAS number is 68412-29-3. Accurate identification through the CAS number is vital for regulatory compliance, inventory management, and supply chain traceability.
• Typical Properties: Food-grade corn starch must adhere to specific physical and chemical properties. These often include:
  • pH: Typically between 4.5 and 7.0, ensuring compatibility with other ingredients and stability.
  • Loss on Drying: A limit on moisture content (e.g., ≤14%) is crucial for shelf stability and accurate weighing.
  • Ash Content: A low ash content (e.g., ≤0.3%) signifies a purer product with minimal mineral impurities.
  • Sulfur Dioxide: Strict limits (e.g., ≤0.004%) are in place due to its potential use as a bleaching agent.
  • Heavy Metals and Microbial Limits: Compliance with regulations on heavy metals (e.g., ≤20ppm) and total microbial counts (TAMC, TYMC, absence of E. coli) is non-negotiable for food safety.
• Appearance: Corn starch is typically a white powder, indicative of its refined nature.
