Procuring high-quality Sodium Stearoyl Lactylate (SSL/E481) is fundamental to achieving consistent results in food production. Key technical specifications define its quality and functionality. First, appearance should typically be a cream-colored powder or flakes with a characteristic mild odor. The assay (content of sodium stearoyl lactylate) is critical, often required to be not less than 90-98%. Acid value and lactic acid content are important indicators of proper esterification. Loss on drying measures moisture content, affecting powder flowability and stability. Sodium content and heavy metal limits (like lead and arsenic) must comply with strict food-grade standards to ensure safety. Reputable suppliers provide a Certificate of Analysis (CoA) for each batch, verifying compliance with these specs and relevant food pharmacopoeias (like FCC, USP, or E481 standards). Partnering with a reliable supplier who guarantees consistent, high-purity SSL is an investment in your product's quality and your brand's reputation.
