Acetylated distarch adipate

Acetylated distarch adipate (CAS 63798-35-6), also identified as E1422, is a chemically modified starch produced by dual treatment with acetic anhydride and adipic anhydride. This dual modification delivers superior freeze-thaw stability and resistance to retrogradation compared to native starches, making it a reliable thickener and stabilizer across demanding food processing environments.

In processed foods, E1422 maintains consistent texture and viscosity in sauces, dressings, soups, and fruit pie fillings that undergo freeze-thaw cycles or high-temperature processing. Dairy applications such as yogurts, cream-based desserts, and processed cheese benefit from its emulsification and water-binding capacity, which prevents syneresis and phase separation during shelf life.

In the paper and pulp industry, it functions as a surface sizing and coating agent, improving paper strength and printability. Textile manufacturers apply it as a warp sizing agent to reduce yarn breakage. Acetylated distarch adipate is supplied as a white to off-white powder in food-grade and technical grades. The food-grade specification conforms to FCC and E1422 regulatory standards.

Defined substitution levels govern the acetyl and adipate content within the chemical structure. Packaging typically ranges from 25 kg bags to bulk quantities depending on specific application requirements.
