    Food Grade Sodium Metabisulfite (SMBS, CAS 7681‑57‑4) is a versatile and essential food additive recognized globally for its powerful bleaching, antioxidant and preservative properties. Also known as sodium pyrosulfite and coded E223, it is processed through advanced purification and crystallization technology, achieving a high purity of over 96.5%. With ultra-low heavy metal, arsenic and moisture indicators, the product eliminates harmful residues and meets strict international food safety standards, making it safe for direct food contact and industrial food production.

    This high-performance SMBS boasts multiple core functional advantages that solve key pain points in food processing. Firstly, it acts as an efficient food bleaching agent, effectively fading yellow and dark pigments in flour, pastries, candies and preserved fruits, improving product brightness and appearance quality. Secondly, its strong antioxidant capacity can block food oxidation reactions, prevent enzymatic browning of fruits, vegetables and aquatic products, and retain the original fresh color and nutritional state of raw materials. In addition, sodium metabisulfite has excellent bacteriostatic and antiseptic effects, which can inhibit the growth of mold, yeast and spoilage bacteria, effectively extending the shelf life of canned food, beverages, grain products and seafood ingredients.

    With mild reaction characteristics, stable performance and wide formula compatibility, food grade sodium metabisulfite is suitable for diversified food processing scenarios. It is commonly used as a flour conditioner, bakery loosening agent, fruit and vegetable fresh-keeping agent, and beverage antioxidant. Different from single-function additives, SMBS integrates multiple effects to reduce production costs and improve finished product stability. All our products undergo strict batch testing and quality inspection, with consistent indicators and reliable safety. Supported by complete export qualifications and mature global supply chain, we provide stable bulk export supply and cost-effective food additive solutions for global food factories and processing enterprises.
