E1422 - acetyliertes Distärkeadipat

Origin

Acetylated distarch adipate (E1422) is a modified starch derived from the chemical modification of starch. The starch base can originate from various sources, including corn, potato, tapioca, wheat, or rice. The modification process involves acetylation and treatment with adipic anhydride, which cross-links the starch molecules. This process alters the starch's properties, enhancing its stability and functionality in food applications.

Usage

E1422 is used as a thickening agent, stabilizer, and binder in a wide range of food products. Its primary function is to improve the texture and consistency of foods, providing a smoother mouthfeel and preventing syneresis (water separation). It is commonly found in sauces, gravies, yogurts, desserts, processed fruits, and canned goods. The modified starch provides improved freeze-thaw stability and resistance to high temperatures and acidic conditions, making it suitable for various processing methods. It is also used in some non-food applications, such as adhesives and paper coatings.

Side Effects

Acetylated distarch adipate is generally considered safe for consumption. The European Food Safety Authority (EFSA) and the Food and Drug Administration (FDA) have evaluated its safety and have not established a numerical Acceptable Daily Intake (ADI) due to its low toxicity. However, as with any food additive, excessive consumption may lead to gastrointestinal discomfort in sensitive individuals. Some individuals with starch intolerance may experience bloating or diarrhea. Regulatory bodies have set limits on the levels of residual modifying agents (acetic anhydride and adipic anhydride) to ensure consumer safety. It is important to note that the modification process does not typically introduce allergenic proteins if the starting starch material is derived from wheat; however, proper labeling is required to indicate the starch source.

Regulatory Status

E1422 is approved for use as a food additive in many countries, including those in the European Union, the United States, Canada, and Australia. Regulatory bodies such as EFSA and the FDA have established specifications and purity criteria for acetylated distarch adipate to ensure its safety and quality. These regulations specify the maximum permitted levels of residual modifying agents and other contaminants. Food manufacturers are required to comply with these regulations to ensure that the additive is used safely and effectively.
