Introduction to the Molisch Test

The Molisch test, named after the Austrian chemist Hans Molisch, is a sensitive chemical test used for detecting the presence of carbohydrates (sugars). It is a general test that can be applied to any type of carbohydrate, including monosaccharides, disaccharides, and polysaccharides, though it is more commonly used to detect the presence of carbohydrates in a solution rather than to quantify them.

The Molisch test serves as a general preliminary screening for carbohydrates. A positive result indicates that a substance contains a carbohydrate component, though it does not distinguish between specific types like glucose, fructose, or starch. 2. Principles of the Reaction Introduction to the Molisch Test The Molisch test,

• No liquid sample needed (works with solid patches).
• Reduced reagent use (drops vs. mL).
• Field-friendly – can be stored after spotting.

Jika tidak terbentuk warna ungu (atau hanya warna cokelat akibat oksidasi asam), maka sampel tersebut tidak mengandung karbohidrat. Protein atau lipid murni tidak akan memberikan hasil positif pada uji ini. Mengapa Menggunakan Asam Sulfat Pekat? No liquid sample needed (works with solid patches)

at the junction (interface) between the acid and the test layers confirms the presence of carbohydrates. Negative Result

❌ Negatif: Tidak terbentuk warna ungu (biasanya tetap hijau atau bening). ⚠️ Hal Penting untuk Diketahui
