Determination of Coenzyme Q10 in Food

Introduction

In Japan, coenzyme Q10 has traditionally been used as a pharmaceutical for improving myocardial metabolism. In accordance with revisions to the Food and Medicine Differentiation List (Pharmaceuticals and Food Safety Bureau, Ministry of Health, Labor and Welfare, Japan) in 2001, coenzyme Q10 was moved to the food section of the list. It is now the focus of attention as a food supplement. According to the Japanese Pharmacopoeia, which lists coenzyme Q10 under the pharmacological name, “Ubidecarenone”, the recommended analysis method for coenzyme Q10 is the HPLC method. Here we introduce an analysis of coenzyme Q10 in commercially available food products using the Prominence Photodiode Array UV-Vis detector SPD- M20A.
