Typically, at the time of harvesting saffron, the stigmas are separated from the lower part of the red section, which is called style. Therefore, apart from the red part, a stigma also has an orange-yellow part. When there is about 1 to 3 mm of style in one branch, it is called Pushal saffron. This category of saffron has more stigma and as a result it will have a higher coloring power (between 170 and 250 units).
The existence of the yellow part in Pushal saffron is a sign of the originality of saffron in the eyes of many consumers and buyers. Because connecting the stigma to the style is a strong proof of the health and originality of the saffron string, and in this way the buyer will be sure that (s)he is not buying fake saffron.
