Although Persian Sargol is considered as the premium saffron, there is another variation of Sargol Saffron. If three stigma threads are attached together and form a cluster, this type of saffron is called Negin. Since production of Negin saffron is an extremely delicate and precise manual skill, it is the most expensive type of saffron and very limited to offer. The ISO reading of Negin is usually more than 270.
Sargol (All Red)
This grade consists of ONLY dark red stigma tips and has the highest quality compared to the other types. Sargol saffron is the pure saffron with no broken stand and has the ISO reading of 260-270. Due to accumulation of saffron`s active components in stimas, Persian Sargol has a very strong arom and rich coloring capacity.
Pushal saffron is the stigma part of the plant attached to a 1-3 mm style end. According to ISO 3632 system, this type falls into grade II category that has a color reading of up to 250. Although Pushal does not have Sargol`s pure texture and premium quality, but some consumers prefer to purchase Iranian Pushal to be assured of saffron validity and authenticity.
Although Saffron powder is not a grade of Saffron, it is prepared by fine grinding of Sargol, Pushal and Bunch parts of the plant. This product has a slightly lighter color compared to Sargol and Pushal and its coloring capacity is obviously less. The manufacturing process is done by superior technology to avoid loss of Persian saffron`s quality. Saffron powder can be easily adultered and mixed with other ingredients such as artificial dye and turmeric, so it has always to be obtained from trusted source.
This grade consists of only yellow-white styles and has a very little aroma and coloring potential.
This grade is relatively low strength grade (ISO reading is 70 to 75) and consists of red stigmata plus large amount of yellow style, presented in a tiny bundle.
