Abstract: Vitamins are essential substances for human health and growth. Storage, aging, and processing of foods may cause vitamin loss. There is a need to develop a fast and accurate analytical method for the determination of vitamins in foods. The determination of vitamins in sugar-based matrix is usually a challenging task due to the complexity of the matrix and instability of vitamins. Gummies are sugar-based candies which are fortified with selected vitamins. Until now, no method has been proposed for the determination of vitamins in gummies. In this work, the determination of six water-soluble vitamins and three fat-soluble vitamins is studied by reverse phase liquid chromatograph(RP-LC) with ultra-violet detector at different wavelengths, on a C-8 column using phosphate buffer and acetonitrile as mobile phase.Summary: Separation and determination of the vitamins was achieved by RP-LC. For most vitamins, quantitative results close to the label claim are determined. The stability of the vitamin extracts and potential interference by co- extracted sugar are being investigated to improve these results prior to validation of the final method.Report abuse »
