Detection of original saffron is sometimes very difficult and even experts cannot do it and cheating is revealed only by laboratory tests.

However, detection of original saffron form twigs of saffron is the easiest way because twigs of saffron have three branches and their upper part is like clarion which become narrower as it becomes lower but if the saffron is powdered, the only way of detection is use of laboratory devices.

Other methods are as follows:
If twigs of saffron are very bright, it should be sent to the laboratory.
Corn awn is straight but the top of saffron is curved Pieces of saffron will turn purple or orange in exposure to Butane gas which is due to its potassium but yellow color is created in case of fake saffron (this method is mostly done in laboratories) If we put saffron strands in brown paper and press it, there should be no grease stains and if there is, saffron is fake
Color of saffron strands are insoluble in gasoline which means color of gasoline should not change when we put saffron strands in it.
If we place a few saffron strands in a cup of boiling water, it should not turn white after about 5 minutes and if it does, saffron is fake
If we place saffron in boiling water, its color should turn yellow and not red or dark orange
Color, odor and taste of it is a crucial test for experts. Original taste of saffron is slightly bitter but pleasant and it has slightly spicy odor.
