Iranian Raisin:
It is believed that humans discovered raisins when they happened upon grapes drying on a vine. History books note that raisins were sun-dried from grapes as long ago as 1490 B.C. But several hundred years passed before it was determined which grape variety would make the best raisin.
In Iran we can divide the variety of raisins into Seeded Raisins Unseeded Raisins
Green raisins, rice raisins and currants. Green raisins and rice raisins are obtained from seedless grapes and Currant is provided from variety of seeded grapes. We explain raisins preparation method, because these names are related to raisins preparation method as well as the kind of grapes, which is used in raisins production. In Iran over 200 varieties of grapes have been named in different languages, but it is obvious that most of these names are related to one item that has found different names in different locations.

Why do some raisins have a different color?
Raisin colors vary by drying process. For example, a dark purplish/black raisin is sun-dried. A light to medium brown raisin is mechanically dehydrated in special drying tunnels. A golden to bright yellow raisin is mechanically dried and treated with sulfur dioxide to retain color.

Summary of types (varieties) of processed raisins.
Raisins are produced in three methods:
1) Drying the grapes without using an alkaline solution. (NON_NITRIFIED RAISINS)
2) Grapes cluster is taken into an alkaline solution previously, and then it will be dried in front of the sunlight. These two methods for raisins preparation are used in Iran as well (NITRIFIED RAISINS)
3) Grapes are placed are faced to Sulphur smoke.

Processed Raisins are dried grapes
The processed raisins are prepared from clean, sound, dried grapes; are properly stemmed and cap stemmed except for cluster or uncap stemmed raisins; are properly seeded in seeded styles; are sorted or cleaned, or both; and except for cluster or uncap stemmed raisins, are washed in water to assure a wholesome product.
