Summary	This standard specifies the methods for the determination of fructose, glucose, sucrose, maltose and lactose in foods. The first method of high performance liquid chromatography is suitable for the determination of fructose, glucose, sucrose, maltose, and lactose in grains and grain products, milk and dairy products, fruits, vegetables, and fruit and vegetable products, sweeteners, candies, beverages, and infant foods. The second method, ion chromatography, is suitable for the determination of fructose, glucose, sucrose, maltose, and lactose in food. The third method is the acid hydrolysis-Rhein-Eynon method, which is suitable for the determination of sucrose in food. The fourth method, the Rhein-Eynon method, is suitable for the determination of lactose in infant foods and dairy products.
