E1000 - Cholsäure

Origin

Cholic acid (E1000) is a bile acid produced in the liver of most vertebrates. It is a naturally occurring steroid carboxylic acid and is the most abundant bile acid in humans. It is synthesized from cholesterol and plays a crucial role in the emulsification of fats and the absorption of fat-soluble vitamins in the small intestine. Commercially, cholic acid can be extracted from animal bile or synthesized chemically.

Usage

Cholic acid and its derivatives are used in the pharmaceutical industry as intermediates in the synthesis of various drugs. It is also used in cell culture media to improve the solubility and absorption of certain nutrients. In the food industry, cholic acid has limited direct use, but it can be found in some dietary supplements aimed at improving digestion or fat metabolism. Its primary function is as an emulsifier, aiding in the dispersion of fats in aqueous environments. It is also used in research and development.

Side Effects

Cholic acid is generally considered safe when consumed in normal physiological amounts. However, excessive intake can lead to diarrhea, abdominal discomfort, and potential interference with the absorption of other nutrients. High doses may also affect liver function. Individuals with pre-existing liver conditions should exercise caution. There is no established Acceptable Daily Intake (ADI) set by regulatory bodies for cholic acid as a food additive, as its use is limited and primarily physiological. However, pharmaceutical uses are subject to strict dosage guidelines.

Regulatory Status

Cholic acid is not widely regulated as a direct food additive. Its use is more common in pharmaceutical applications, where it is subject to drug regulations. In the EU, it is listed as E1000, indicating its potential use as a food additive, although specific regulations regarding its usage levels are not widely defined. In the US, cholic acid is generally recognized as safe (GRAS) for specific uses, particularly in pharmaceutical formulations. Regulatory oversight varies depending on the specific application and intended use.
