Water testPlace saffron strands in water. Pure saffron releases its golden-yellow colour slowly, while fake ones release colour instantly or turn the water reddish.
Rub testRub saffron strands between your fingers. Pure saffron doesn’t break easily and leaves a yellow stain, while fake saffron may crumble or leave a reddish colour.
Smell testPure saffron has a distinct, earthy aroma with honey-like sweetness. Fake saffron often smells synthetic or lacks fragrance.
Taste testAuthentic saffron tastes slightly bitter, not sweet. If it’s sweet, it may be adulterated.
Float testDrop saffron strands in water. Real saffron floats initially before sinking, while fake saffron often sinks immediately due to added weight.
Solubility testReal saffron retains its thread-like structure even after soaking in water for hours, while fake strands often dissolve or disintegrate.
Vinegar testMix saffron strands with vinegar. If bubbles form, they may contain impurities like chalk powder.
Thread inspectionExamine saffron threads closely. Pure saffron has uneven, slightly curled strands with tapered ends, while fake ones are often uniform and artificially dyed.
Milk testSoak saffron in warm milk. Pure saffron imparts a golden hue without any residue, whereas fake saffron may leave artificial dye traces.
Paper towel testRub saffron strands on a white paper towel. Pure saffron leaves a yellow stain, while fake saffron may leave red or other dye marks.
