Sodium Metabisulphite - Food Grade
Sodium metabisulphite Food grade is manufactured by Aditya Birla Chemicals (Thailand) Ltd - sulphites division, that is widely used in the food industry as a preservative for products like dehydrated foods, shrimps, bakery items, and biscuits. Beyond food, it is used in starch processing, pharmaceutical and API industries, as it serves as an excipient and preservative. The values as per the TDS are according to the requirements of FDA - Food & Drug Administration of Thailand, FCC - Food Chemical Codex ( FCC XII ), USA BP - British Pharmacopoeia, England.

Application:
1. Food and Beverage Industry: Acts as a preservative and ntioxidant that helps to extend shelf life of the product (Biscuit and Bakery, dried fruits, jams, and pickles etc) 2. In baked products Sodium Metabisulphite is used as a dough conditioner by reducing disulfide (S–S) bonds in gluten proteins, improving dough flexibility without compromising structural integrity. 3. Starch Industry: Prevents enzymatic browning and oxidative degradation during starch extraction and maintains the whiteness. 4. Shrimps & Seafood: Helps to prevent melanosis / discoloration of shell. 5. Pharmaceutical & API: prevent oxidation of sensitive pharmaceutical ingredients.

Sodium Metabisulphite - Tech Grade
Sodium metabisulphite technical grade is manufactured by Aditya Birla Chemicals (Thailand) Ltd- sulphites division that is a versatile chemical used across multiple industries for its reducing and bleaching properties. It is widely applied in photographic processing, chemical synthesis, water treatment, and rubber production. Additional uses include mining, textiles, tanneries, and dye manufacturing, where it functions as a flotation aid, dechlorinating agent, and oxygen scavenger.

Application:
1. Water treatment: Reverse osmosis (RO) desalination, sodium metabisulphite is added for Dichlorination, neutralizing free chlorine before it reaches sensitive membrane systems and acts as a preservative in RO membrane storage to maintain a reducing environment and inhibit microbial enzymes, preventing biofouling and oxidative degradation. 2. Textile: removal of chlorine from fabric before dyeing process, therefore improves the quality of fabric. 3. Photographic industry: Used as developer baths (preserves developing agents from rapid oxidation) and fixers (stabilizes the thiosulfate ion) 4. Mining: . Cyanide treatment: precious metals such as gold and silver are often found within complex polymetallic ores containing other metals like copper, lead, or zinc. It is extracted using cyanide leaching, which dissolves these precious metals into solution. Sodium Metabisulphite (SMBS) is used to detoxify cyanide by oxidizing it into non-toxic byproducts. . Froth flotation is widely used to extract base metals from complex sulfide ores. Air and reagents are added to a slurry to separate minerals; valuable ones float, while others sink. Sulfide minerals have similar surface properties and float together, leading to poor selectivity. This results in lower concentrate purity and increases downstream processing costs. Sodium Metabisulphite (SMBS) acts as a selective depressant, modifying the surface of non-target minerals (like pyrite) to prevent them from floating. 5. Leather treatment: in Pre-Tanning Treatment, sodium metabisulphite (SMBS) is added during deliming to neutralize lime by forming calcium sulphite and oxidize residual sulfides, preventing H₂S formation.
