Date export is one of the most profitable sectors of agricultural trade in Iran and Middle East countries. But the key to success in this competitive market is not only the production of quality products; Rather, maintaining this quality until it reaches the final consumer on the other side of the border. Storage of dates and correct methods of keeping dates play a vital role in preventing spoilage, sugaring and changing the taste of the product. In this comprehensive article, we examine all the standards required for storing this black gold. If you are looking for a successful export, Tek Aghaj Company, as one of the pioneers of the date industry, offers new solutions in packaging and supplying this product.
The importance of basic storage of dates in international trade
Why is date storage so important? Dates are a fruit that, although it looks resistant, it is highly sensitive to changes in temperature and humidity. In the date export process, the product may remain in storage for months or travel long distances. Any mistake in setting the environmental conditions can lead to sourness, pest infestation or color change, which has no result other than the return of the cargo and heavy financial damage.
Using modern storage systems not only increases the useful life of the product, but also preserves its added value. With a deep understanding of these sensitivities, Tek Aghaj company always tries to provide products that are ready to enter the global markets by complying with the highest maintenance standards.
Standard environmental conditions for keeping dates
In order for dates to maintain their original quality, three main factors must be controlled in storage: temperature, relative humidity and ventilation. Each type of date (dry, semi-dry or wet) has different needs.
1. Suitable temperature for different types of dates
Temperature is the most important factor in date storage. Biological activities and growth of microorganisms are directly related to temperature.
- Fresh dates (moist): This type of date is very perishable due to high humidity. The best temperature for moist storage is freezing or below zero (between minus 5 and minus 18 degrees Celsius). At this temperature, the activity of bacteria is stopped and the freshness of the product is preserved. The suitable temperature for their long-term storage is between zero and 4 degrees Celsius. Of course, for short-term periods, the cool temperature of normal warehouses (less than 10 degrees) is also acceptable.
- Dried dates: This type of dates is the least sensitive, but it should still be kept in a cool environment away from direct heat. The ideal temperature is around 10 to 15 degrees Celsius.
Note that temperature fluctuation is the worst enemy of dates. The thermal shock causes the moisture inside the package to condense and create a suitable environment for the growth of fungi. Tek Aghaj consultants always recommend that warehouse refrigeration systems are equipped with accurate sensors and warning systems.
2. Control the relative humidity of the warehouse
The humidity of the date storage environment must be carefully controlled. If the air humidity is high, dates will absorb moisture and become sour or moldy. On the other hand, very dry air causes the fruit to lose its natural moisture and its texture to harden (false sugaring).
Generally, the relative humidity (RH) suitable for most date varieties is between 65 and 70%. For drier cultivars, the ambient humidity can be slightly lower. It is mandatory to use hygrometers and dehumidifiers in specialized date export warehouses.
3. The importance of ventilation and air circulation
Stagnant air can cause the accumulation of gases produced by the fruit and increase the local temperature. Date storage requires an air conditioning system that circulates the air evenly among the pallets. The arrangement of the pallets should be such that there is at least 15 to 20 cm distance between them and the walls so that the air can flow.
Date preparation steps before storage
Correct harvesting and initial sorting
Mechanical damage during harvesting opens the way for microbes to penetrate. Dates whose skin is cracked or crushed should not enter the date export cycle. In the sorting stage, experts must carefully separate the defective dates. Tek Aghaj, by using advanced sorting devices, ensures that only healthy and uniform products enter the final packaging.
Washing and disinfection
Dust and pest waste must be removed from the product before storing dates. Washing with clean water and then drying completely (to prevent moisture build-up) is essential. In some cases, for export to European countries, it is necessary to use special disinfectants or use organic methods to control warehouse pests such as Indian moth.
Fumigation
One of the vital steps in date storage is gasification or fumigation. This operation is done to destroy insect eggs and larvae that may be hidden inside the date. Usually, aluminum phosphide tablets or methyl bromide gas are used (following the permitted dose and health standards of the destination country) in isolation rooms. Failure to do this step correctly can lead to the product being damaged in the middle of the ocean and during transportation.
The role of packaging in long-term storage
Packaging in the export of dates is not only about beauty; Rather, it is a vital protective layer. The type of carton, internal plastic and packaging technology directly affect the shelf life.
- Nano and vacuum packaging: The use of nano bags that control the exchange of oxygen can extend the life of dates by several months. Vacuuming also prevents the growth of aerobic bacteria by removing oxygen.
- Resistant cartons: Cartons must be able to withstand the weight of high pallets and not be deformed by the humidity of the cold room. The use of laminated cartons and three standard layers used by the brand Tek Aghaj ensures load resistance in refrigerated containers.
- Modified atmosphere (MAP): In this advanced method, the composition of the air inside the package is changed (for example, reducing oxygen and increasing nitrogen) so that the respiration of the fruit is slowed down and the spoilage process is delayed.
Common pests and diseases in date storage
Knowing the enemies of dates in storage will help you adopt better preventive strategies.
- Sugaring: This phenomenon is usually not corruption, but the crystallization of natural date sugars. Its main cause is temperature fluctuations and inappropriate humidity. Although it does not change the taste, it makes the appearance of the product unsuitable for exporting dates. Keeping at a constant and suitable temperature is the best way to prevent it. Fermentation: If the humidity of dates is higher than the limit (usually above 25%) and the temperature of the warehouse rises, the yeasts are activated and convert the sugar into alcohol and acid, which causes the smell of sourness. They feed on dates. Their excrement causes secondary fungal contamination.
The quality control team of Tek Aghaj monitors the early signs of pests or changes in quality with periodic inspections in the warehouses to ensure the health of the cargo.
Key points of date transportation (Transport)
- Reefer Containers: For export to distant destinations, the use of refrigerated containers with adjustable temperature is required. Before loading, the container must be clean, odorless and pre-cooled.
- Arrangement in the container: The cartons must be arranged in such a way that the air circulation vents on the bottom of the container are not blocked. Overstuffing the container causes the cargo to suffocate and spoil. Data Logger: The use of temperature and humidity data loggers along the way assures the exporter and the buyer that the date storage conditions have been met during sea or land travel.
