Qualitative Analysis of Carbohydrates: A Modified Approach to the Molisch Test

Abstract Carbohydrates serve as a primary energy source and structural components in biological systems. The identification of carbohydrates in unknown samples is a fundamental procedure in biochemistry. The Molisch test is the standard general test for the detection of carbohydrates. This article discusses the principle, procedure, and application of the Molisch test, highlighting a modified ("patched") procedure designed to enhance safety, efficiency, and color differentiation in the detection of trace carbohydrate quantities.

3.3. Patched pada Prosedur (Teknik Layering)

Modifikasi utama:

• If user selects "no reaction" but sample is known carbohydrate → alert to recheck acid/reagent order
• If ring color is brown but sample is pure carb → warn about overmixing or excess acid

Application: Acid must be added slowly down the side of the test tube to form a distinct layer without mixing. jurnal+uji+molisch+karbohidrat+patched

3. Introduction

• Briefly explain the Molisch test principle:
  Carbohydrates + α-naphthol + H₂SO₄ → furfural derivatives → purple condensation product.
• Mention limitations of conventional test (requires liquid sample, large volume, hazardous acid handling).
• Introduce the patched method:
