Introduction
Raisins are one of the important and valuable agricultural products of Iran, obtained from drying grapes. Among the raisin producing regions, Takestan County in Qazvin Province holds a special place due to its suitable climatic conditions, high quality grapes, and traditional and industrial drying methods. Vineyard raisins have always been of interest in domestic and foreign markets due to their sweet taste, high nutritional value, and extensive applications in the food and pharmaceutical industries. In this article, we will examine the properties, types, and uses of grape raisins.
The history and importance of raisins in the vineyard
Due to its specific geographical conditions, Takestan County is considered one of the main hubs for grape and raisin production in Iran. Since ancient times, the people of this region have been drying grapes and producing high-quality raisins using traditional and natural methods. Today, with the advancement of technology, this process is also carried out industrially, and higher quality and longer-lasting products are being offered to the market.
Types of Raisins in the Vineyard
Raisins are divided into different types based on the type of grape, drying method, and sweetness level. Some of the most important types of raisins produced in the vineyard include:
1. Sunny raisins
Sunny raisins are one of the most natural types of raisins, prepared without the use of chemicals and only by exposure to sunlight. This type of raisin has a dark brown color and a sweet, natural flavor.
2. Tangy raisins
Pickled raisins are prepared using a pickling solution (a weak solution of potassium carbonate and special oils). This method speeds up the drying process of the grapes and maintains the lighter color of the raisins. Acid raisins have a more beautiful appearance and amber yellow color than sunny raisins.
3. Green raisins
This type of raisins is obtained from special grapes that are produced using the shade-dried method. Green raisins have a soft texture, light green color, and a mild flavor, and are mostly used in nuts and baking.
4. Raisins
Raisins are made from large, seeded grapes and are larger in size and have a richer flavor than other types of raisins. This type of raisin is highly recommended for boosting memory and increasing energy due to its high antioxidant and nutrient content.
