The Seliwanoff color reaction, discovered by Russian chemist Feodor Feodorovich Selivanov, is used to differentiate between aldoses and ketohexoses based on their dehydration and reaction with resorcinol in acidic conditions. Ketoses like fructose react faster than aldoses like glucose, leading to a

Preparation of reagents such as Barfoed's reagent and Seliwanoff's reagent is essential for detecting monosaccharides in food analysis. Barfoed's test utilizes a mixture of acetic acid and copper(II) acetate to detect reducing sugars, while Seliwanoff's reagent helps identify ketoses in solutions. U

The lab features qualitative tests for identifying different types of carbohydrates such as pentose and hexose monosaccharides. Tests include Bial's test to distinguish between sugar types, Seliwanoff's test for aldoses and ketoses differentiation, and Iodine test for polysaccharide detection. Each
