Starch, oxidized #CAS65996-62-5

Oxidized starch is a modified starch derivative. Partial hydroxyl groups on the glucose units of the starch molecular chain are oxidized into carboxyl groups and aldehyde groups. It can swell and dissolve in hot water to form low-viscosity, clear and stable aqueous solution. It is insoluble in ethanol, acetone and most organic solvents. It features excellent film-forming ability, and the formed film is flexible, uniform and not easy to crack. It keeps stable under neutral and weakly alkaline conditions. In strong acid environment or under long time high temperature, the molecular chain will hydrolyze and break, leading to further decrease of viscosity. It is slightly hygroscopic. It has good compatibility with many water-soluble additives. It will not produce hazardous decomposition under normal storage conditions.

Applicaion of Starch, oxidized

Starch, oxidized is used as thickener; emulsifier; binder. It can be used as a binder in the surface seasoning of fried foods and in starch jelly. In bread production, it can improve gas retention, shorten fermentation time, and increase bread volume.

Oxidized starch (E1404, CAS 65996-62-5) is a low-viscosity modified starch with outstanding film-forming and binding performance. In the food sector, it functions as thickener, stabilizer, binder and coating agent. It is widely incorporated into salad dressings, tomato sauces, gravies, instant soups, canned fillings, meat products, puddings, jelly, gummy confectionery and fried batter coatings. It delivers mild thickening without excessive viscosity, forms clear, glossy and flexible films, reduces oil absorption during frying, prevents product stratification and syneresis, and stabilizes texture over shelf storage. In papermaking, it is commonly adopted as surface sizing agent and coating binder. It strengthens paper surface strength, boosts sheet smoothness and surface gloss, lessens surface dusting, improves ink receptivity and print sharpness, and enhances binding power between mineral pigments and paper fiber for coated paper, cultural paper and packaging board. In textile production, it works as warp sizing agent. It spreads evenly on yarn surfaces to form a thin, tough protective film, increases yarn abrasion resistance, decreases end breakage rate on weaving looms and raises overall weaving efficiency. It is also widely used as adhesive for corrugated cardboard, paper tubes and gypsum boards. In pharmaceutical manufacturing, it acts as tablet binder and filler, helping maintain uniform hardness and stable disintegration performance of tablets. It can also be used in cosmetic and personal care formulations as texture modifier and stabilizer, and applied in biodegradable film production for eco-friendly packaging materials.
