SI.No.	Test	Observation	Inference
1.	Fiehe’s test Take about 3ml of honey + 2ml of ether and shake thoroughly and allow the 2 layers to separate and evaporate to dryness. The upper etherial layer is separated and put in a china dish and evaporate, to the residue add 1% resorcinol and HCl.	Transient pink colour Permanent red colour	Pur honey Adulterated honey(Invert sugar)
2.	Molisch’s Test Honey is treated with alpha Napthol and concentrated sulphuric acid	Purple colour	Presence carbohydrate
3.	Reducing Sugar Test Heat honey to this add a drop of mixture of Fehling’s solution A & B	Brick red colour of cuprous oxide	Presence monosaccharide
