reduce the likelihood of counterfeiting.
Saffron of grade 1, grade 2 and grade 3 is in the group of saffron shoals.
Pushal saffron contains the stigma with an approximate 3-5 mm style.

This kind of saffron has lower color strength respect to Sargol saffron. It is produced at the early stages of harvesting season. This saffron grade is not cut like sargol and therefore contains more yellow parts from the style of the plant and higher floral waste. It contains 5% flower waste. It is called mancha saffron inSpain. 101 kg of saffron flowers produces 1kg
of sargol saffron.

This kind of saffron is pure and contains the stigma without the style. The Threads or stigma of the flower is the actual source of saffron. 105-115 kg of saffron flowers produces 1kg of Sargol saffron. Persian Sargol saffron in Iran exceeding ISO 3632 Grade 1 standard and has very high quality. In Spain it is called cope saffron.

Negin saffron:

Negin saffron is a special type of pooshal saffron, in which the 3 branches of red and thick chalk and without style part (yellow) are separated from existing strands and bulky saffron is produced. Negin saffron is the richest
and most expensive saffron type and has the highest coloring power (between 230 and 270 units). The production and sale of Pallal Negin saffron is usually decreasing due to the times consuming process and the more processing required for processing.

White saffron:

By separating the Sargol from the bunch, the root remains, which is called white saffron or Konj in Iran. In Europe, this part is known as Style. Scientific research shows that valuable materials of saffron are only in its red color. This material (especially crocin as a saffron color factor) is transmitted from the stigma to the Style due to the movement of the plant tissue, due to the presence of more moisture in the Style, in appearance more perfume comes from the Style. White saffron is not included in the category of saffron, but due to its beautiful color and appearance, it is not possible to cheat.
