Iranian Sultana Raisins—famous for their golden color, natural sweetness, and chewy texture—are among the most sought-after dried fruits in the global market. Grown primarily in sun-rich regions like Takestan and Malayer, they are carefully processed and exported worldwide. However, to preserve their premium quality, it’s essential to store them under the right conditions—especially during transportation and long-term warehousing.

Why Storage Matters

Due to their high natural sugar content and low moisture, Sultana raisins are shelf-stable—but only if stored properly. Improper storage can lead to:

•  Clumping and crystallization of sugars

•  Hardening of texture

•  Loss of flavor

•  Mold growth due to excess humidity

•  Insect contamination

To avoid these issues and maintain product quality from farm to fork, both exporters and importers should follow industry-standard storage practices.

Ideal Storage Conditions for Sultana Raisins

Here’s what you need to know about proper storage:

1. Temperature

•  Ideal storage temperature: 5°C to 10°C (41°F to 50°F)

•  For long-term storage (over 6 months), use cold storage at 0°C to 4°C.

•  Avoid exposure to high temperatures, which can degrade color and flavor.

2. Humidity

•  Relative Humidity (RH) should be kept between 45% to 55%.

•  High humidity promotes mold growth; low humidity causes excessive dryness and hardening.

3. Packaging

•  Raisins should be packed in airtight, food-grade packaging, such as:

o  Polyethylene (PE) bags

o  Vacuum-sealed pouches

o  Carton boxes lined with plastic

•  Bulk packaging should be layered with moisture barrier liners to avoid moisture exchange.

4. Light Exposure

•  Raisins are sensitive to light, especially UV, which can affect their color and reduce shelf life.

•  Always store in dark or shaded areas, away from direct sunlight.

5. Pest Control

•  Storage facilities should be insect- and rodent-proof.

•  Use of food-safe pest control systems like pheromone traps is recommended.

6. Air Circulation

•  Ensure adequate air ventilation in storage rooms to avoid condensation.

•  Avoid storing raisins near strong-smelling substances as they can absorb odors.

Shelf Life of Iranian Sultana Raisins

•  Under optimal conditions: 12 to 18 months.

•  Once opened: should be consumed within 6–8 weeks, or refrigerated to extend freshness.

Tips for Importers and Distributors

•  Request COA (Certificate of Analysis) and MOQs with recommended shelf life from exporters.

•  Store in a cool, dry, and hygienic warehouse.

•  Use First-In, First-Out (FIFO) inventory management to reduce spoilage.
