Overview
What is Sialic Acid (N‑Acetylneuraminic Acid)?Sialic Acid, chemically named N‑Acetylneuraminic Acid (Neu5Ac, CAS: 131-48-6), is a member of the sialic acid family and a naturally occurring carbohydrate derivative. It exists naturally in glycoproteins and glycolipids on the surface of animal cell membranes, and is also the most representative characteristic component in traditional bird’s nest, hence the common name “Sialic Acid (Bird’s Nest Acid)”. Commercially available Sialic Acid raw materials for industrial production are mostly manufactured by microbial fermentation, not extracted from bird’s nest. Powered by biosynthetic technology, high-purity products can be produced stably and on a large scale, breaking the constraints of limited natural bird’s nest output and volatile pricing, with controllable quality and consistent batches. The finished product appears as white crystalline powder. It features excellent water solubility, nearly odorless, good powder flowability and convenient feeding for processing. It also shows favorable compatibility with most food and cosmetic raw materials, suitable for a wide range of formulation systems. From a regulatory perspective, N‑Acetylneuraminic Acid is a novel food ingredient approved by China’s National Health Commission. It can be applied in nutritional foods, solid beverages, pressed candies, oral liquids and other dietary supplement foods. Regulations clearly stipulate that this ingredient shall not be used in infant foods. Meanwhile, N‑Acetylneuraminic Acid can also be used as a cosmetic formulation ingredient, added into serums, facial masks, skin lotions, creams and other cosmetic formulations.
