E1451 - Acetylierte oxidierte stärke

Origin

Acetylated oxidised starch (E1451) is a modified starch derived from the treatment of starch with acetic anhydride and oxidising agents such as sodium hypochlorite. The starch source is typically corn, potato, tapioca, or wheat. The acetylation process introduces acetyl groups into the starch molecule, while oxidation introduces carbonyl and carboxyl groups. These modifications alter the starch's properties, enhancing its stability, texture, and functionality in food applications.

Usage

E1451 is used as a thickener, stabilizer, binder, and emulsifier in a wide range of food products. It improves the texture and mouthfeel of processed foods, prevents syneresis (water separation), and enhances the freeze-thaw stability of frozen products. Common applications include sauces, dressings, soups, processed fruits and vegetables, bakery fillings, and dairy products. It is also used in non-food applications such as adhesives and paper coatings. The level of use varies depending on the specific application and desired effect.

Side Effects

Acetylated oxidised starch is generally considered safe for consumption. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) 'not specified', meaning that, based on available data, the intake of E1451 at levels necessary to achieve the desired technological effect does not represent a health concern. However, as with any food additive, excessive consumption may lead to gastrointestinal discomfort in sensitive individuals. Regulatory bodies such as the EFSA and FDA have evaluated the safety of E1451 and have approved its use in food under specified conditions.
