Propane-1,2-diolester von Fettsäuren

Origin

E477, also known as Propane-1,2-diol esters of fatty acids or Propylene Glycol Esters (PG esters), are synthetic emulsifiers produced by esterifying propylene glycol with edible fatty acids. The fatty acids can be derived from vegetable oils or animal fats. The properties of the resulting ester depend on the type of fatty acids used. These esters are mixtures of mono- and diesters of propane-1,2-diol with fatty acids.

Usage

E477 functions primarily as an emulsifier, stabilizer, and aerating agent in food products. It is used to improve the texture, stability, and appearance of various foods. Specific applications include: baked goods (cakes, pastries), where it improves aeration and crumb structure; emulsified sauces and dressings, where it helps to stabilize the emulsion; non-dairy creamers, where it contributes to a smooth texture; and whipped toppings, where it aids in foam formation and stability. It is also used in some confectionery products and frozen desserts. The permitted levels vary depending on the food application, adhering to Good Manufacturing Practices (GMP).

Side Effects

Propylene glycol esters are generally considered safe for consumption at the levels typically used in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 'not specified', meaning that, based on available data, the total dietary intake of the food additive arising from its use at the levels necessary to achieve the desired technological effect does not represent a hazard to health. However, as with any food additive, excessive consumption could potentially lead to gastrointestinal discomfort in sensitive individuals. There are no significant concerns regarding carcinogenicity, genotoxicity, or reproductive toxicity at the levels used in food.

Regulatory Status

E477 is approved for use as a food additive in many countries, including those in the European Union (EU) and the United States. In the EU, it is subject to Regulation (EC) No 1333/2008 on food additives. In the United States, it is regulated by the Food and Drug Administration (FDA) under specific conditions of use. The regulatory status ensures that the additive is used within safe limits and according to established guidelines.
