Saffron, scientifically known as "Crocus Sativus”, is a perennial plant that is harvested in southwest Asia, southern Spain, and southern Europe. This plant has a spherical corm (crocus bulb) covered with a brown membrane, stem, six purple flowers, and 3 threads of vivid crimson stigma, which is the most important commercial part, and in fact, it is what we commonly know as Saffron. The stigma contains fatty substances, minerals, and mucilage. Its pleasant fragrance is because of the colorless tropane essential oil and an oxygenated compound with cineole called safranal. The slight bitterness of saffron is due to picrocrocin. And finally, crocin is the carotenoid pigment of saffron
To classify different types of saffron, the method of detaching the stigma from the style is usually considered. Saffron is divided into different categories. The higher the purity and quality of Saffron, the higher its coloring power and aroma. The grade of saffron depends on several factors such as the quality and size of the corm, the place of cultivation, and the method used to make it dry. In general, saffron is divided into 5 different categories:
Bunch saffron is obtained by stacking and drying the full strings of saffron, consisting of stigma and style part with its yellow color. The style size attached to stigma varies from 3 to 5 mm and depending on the quality of Saffron, the stigma can be longer or shorter. The power of coloring in bunch saffron is between 120 and 150 units.
By separating sargol saffron from the bunch, in Iran, the remaining part is called Sefid (white) or konj saffron. Cream is another name used worldwide for this part. In Europe, it is known as White or Style. This part has the properties of Saffron to some extent but lacks the pigmentation of other types. Contrary to rumors that the fragrance of konj is more than the sargol and other types, according to scientific studies, the valuable ingredients of Saffron lie only in its red stigma. Style is not a category of saffron, but its beautiful color and appearance also the fact that it cannot be cheated, attract people's attention.
Negin saffron consists of three large & thick threads of red stigma completely separated, which, do not contain any part of the yellow style. The pieces of threads are smooth, stuck together, and free from frizz. Negin saffron is the most luxurious and expensive type of saffron and with a minimum of 220 units, it has the highest pigmentation power.
In this type, red stigmas completely separated from each other and fully detached from style make pure saffron. In addition to Sargol, Sargalam, Sarrisheh, and Mumtaz are also used for this type of Saffron. In sargol Saffron, the difference in quality causes a different coloring grade. The pigmentation spectrum of sargol saffron varies between 200 to 250 units.
In this kind of saffron, the three threads of red stigma were attached together along with 1 to 3 mm of the style part with yellow color. Depending on its quality, the coloring power of pushal saffron is from 180 units and above.
There are some tips which should be kept in mind when storing saffron. Especially if you keep it ground and in form of powder, it should be kept away from light, moisture, and heat (max. 20 degrees Celsius) and maintained in covered containers because the essence (aromatic substances) of saffron is volatile and can be evaporated, over time, if it stores in an open package. In this case, its taste, aroma, and medicinal effects will be reduced in a short time and its quality will be significantly lost. The package should be made by metal, glass, polyethylene, and also laminated aluminum foil pouch and be preferably colored. In order to prevent compression and crushing during transport, the inner packages should be placed in a carton or in wooden & metal boxes. In general, saffron packages should be moisture-proof, air-tight, and made of materials with no negative effects on the product itself.
One of the distinctive features of this plant is the growth of its flower before any other vegetative organs. It begins to grow in the fall and ends in the spring. Its flowers should be harvested early in the morning before warming up the weather. Propagate of saffron is exclusively done by its bulb (Corm). Harvesting operation includes picking the flowers and separating the stigmas from other parts of the flowers, and finally drying the stigmas. The lifespan of flowers is 3 to 4 days. On average one kilogram of saffron flowers is almost equivalent to 2500 flowers. After harvesting the flowers and separating the stigmas, the most important parameter in the quality of saffron is how to dry them. It should be done in a clean environment, in a short time (about 2 to 3 hours), and more importantly at an adequate temperature. At present, all stages of flower harvesting and stigma separation are done manually.
The factors effective on processing a good Saffron
• Soil type and planting depth (about 25-20 cm) are really important factors.
• Allocating appropriate time for irrigation and proper irrigation volume.
• Shortening the period of utilization of farm for planting to 6 years (before bulbs size reducing happening).
• Adding rotten animal manure and suitable soil nutrients every year to fertilize the soil and improve efficiency.
• By choosing larger bulbs, the yield becomes more productive, both in the first year and the following years.
• Number of bulbs planted per square meter
• Harvesting of flowers at the right time and early in the morning, before sunrise.
• The period of saffron farm flowering is usually 15 to 25 days and from the day 7th to 9th, the quantity of flowers increases.
• Choosing the right cultivation method, preferably row system planting.
• Separating the stigma from other parts of the flower at fast as possible and drying it quickly and correctly.
