Abstract： Choline is an important water-soluble micronutrient that is often classified as “vitamin-like.” It is critical for cell membrane structure and function and in synthesis of the neurotransmitter acetylcholine. Choline has been added in foods for special dietary users with a strict limitation to the amount of addition. Thus， accurate determination of choline has great significance. In this paper， the sample treatment， instrument， reagent and automation of the method for determination of choline in foods for special dietary users are brieflfly presented， so as to provide a reference for testing personnel.

Keywords： choline; foods for special dietary users; detection method; sample treatment
