Qualitative tests for the adulterant detection are advantageous because of it being selective in nature. Because of procedural variations in these tests, the inferences drawn when these tests are used remains doubtful sometimes. One of such sources of variation, intensity of heating in some tests for detection of glucose, sucrose, ammonium sulphate and formalin were evaluated. The optimum period of heating was found to be 3 minutes for Barfoed test for glucose, 5 minutes for Seliwanoff’s test for sucrose, 20 seconds for Phenol test for ammonium sulphate, 1 minute for Leach test using direct heating and 4 minutes for heating on boiling water bath for formalin.
