Determination of Choline in Infant Formula and Other Food Samples by IC

Introduction Choline is a water-soluble micronutrient vital to cell membrane integrity, support of methyl group metabolism, and nervous system activity.1 It is present as free choline in small quantities in a wide variety of foods and frequently found in its esterified forms.2 Choline can also be found in fortified foods and dietary supplements; e.g., choline is a required additive in many infant formulas. It is therefore important to determine the choline content of common foods.
