The industrial drying process of dried plums (prunes) is a highly specialized and controlled procedure aimed at preserving the fruit’s nutrients, flavor, texture, and overall quality while ensuring that the final product meets food safety standards and has a long shelf life. This process involves several steps, from harvesting fresh plums to packaging the dried fruit for distribution. Below is a detailed explanation of the industrial drying process used for dried plums.

1. Harvesting and Pre-Processing

Before the actual drying process begins, fresh plums must be carefully harvested at the right stage of ripeness to ensure optimal quality. Overripe or underripe plums may not dry properly or might result in a poor final product. The ideal plums for drying are those that are fully ripe but not overripe, with good sugar content and texture.

Steps in Harvesting and Pre-Processing:

• Harvesting: Plums are harvested by hand or by machine, depending on the scale of production. The fruit must be handled delicately to avoid bruising or damage that could affect the final quality of the dried product.
• Washing and Sorting: The plums are thoroughly washed to remove dirt, pesticides, and any other contaminants. After washing, plums are sorted by size, color, and quality to ensure uniformity in the drying process. Damaged or unripe fruits are removed.
• Pitting: The next step in the process involves removing the pit from the plums. In most industrial drying processes, plums are pitted before drying, but in some cases, they may be left intact to retain more of their natural moisture. The pitting process is done mechanically to ensure high efficiency.
• Blanching (Optional): In some cases, plums may undergo a blanching process where they are briefly immersed in boiling water or steam to soften the skin and help preserve color. This step can also help reduce microbial contamination and improve the drying speed.

2. Pre-Treatment (Optional)

To improve the drying process and ensure a better final product, some manufacturers may apply pre-treatments to the plums. These treatments are particularly important for maintaining the fruit's appearance, texture, and nutrient content.

Common Pre-Treatments Include:

• Sulfur Dioxide Treatment: Some producers use sulfur dioxide (SO₂) as a preservative to prevent oxidation and preserve the fruit's color. This step is optional and is often used for plums that will be consumed as whole dried fruit. Sulfur dioxide helps retain the dark purple color of the plums, but it can also affect the flavor if not properly controlled.
• Sweetening or Coating: Some manufacturers dip plums in a sugar solution or a natural coating to enhance their sweetness before the drying process begins. This is especially useful for commercial-grade dried plums where the flavor profile needs to be consistent and appealing to consumers.

3. Drying Process

The drying process is the most crucial stage in the production of dried plums (prunes). Industrial dryers are designed to remove moisture from the plums while preserving their nutritional value, texture, and flavor. The drying process must be done carefully to prevent over-drying or under-drying, both of which could negatively impact the final product.

Types of Drying Methods Used in Industry:

a) Hot Air Drying (Convection Drying)

This is one of the most widely used methods for industrial plum drying. In this process, plums are placed on trays or conveyor belts, and hot air is blown over the fruit at a controlled temperature.

• Temperature: Typically ranges between 50°C (122°F) and 70°C (158°F), depending on the size and moisture content of the plums.
• Drying Time: The process can take anywhere from 24 to 48 hours to dry the plums to the desired moisture content (around 20-25% moisture content).
• Air Circulation: Constant airflow ensures even drying and prevents the fruit from becoming sticky or clumping together. The fruit is continuously moved or rotated to ensure uniform exposure to hot air.
• Advantages: It is an efficient method for large-scale production, and the process can be monitored and adjusted for optimal results.

b) Tunnel Drying (Continuous Drying)

In tunnel drying, plums are placed on a conveyor belt that passes through a long, heated chamber. Hot air is blown through the tunnel to remove moisture from the plums.

• High Efficiency: This method is highly efficient for drying large quantities of plums. It is often used in high-volume production facilities.
• Uniform Drying: The temperature, humidity, and airflow can be precisely controlled along the length of the tunnel, ensuring uniform drying across all plums.
• Drying Time: The total drying time is usually shorter than traditional hot air drying due to the continuous airflow and uniform temperature.

c) Freeze Drying (Lyophilization)

Freeze drying is a more advanced and expensive technique used to preserve the maximum amount of nutrients, flavor, and texture in the dried plums. In this process, the plums are first frozen, and then the moisture is removed through a process called sublimation, where ice is directly converted into vapor without passing through the liquid phase.

• Nutrient Preservation: Freeze-dried plums retain more of their vitamins, antioxidants, and minerals compared to traditional drying methods.
• Texture and Flavor: Freeze drying also preserves the natural color, flavor, and texture of the plums, making them taste fresher and more appealing.
• Shelf Life: Freeze-dried plums have an extended shelf life and are ideal for high-end or premium markets.
• Cost: While freeze drying produces a superior product, it is more expensive than other methods and requires specialized equipment.

d) Solar Drying

While solar drying is not as common in large-scale industrial settings, it can be used in certain regions where sunlight is abundant. In this method, plums are laid out on solar drying beds or trays that are exposed to sunlight.

• Energy-Efficient: Solar drying is eco-friendly and uses natural energy, reducing costs related to electricity or fuel.
• Longer Drying Time: Solar drying takes much longer than other methods and is highly dependent on weather conditions. It is often combined with other drying methods in commercial production to speed up the process.

4. Moisture Content and Monitoring

Throughout the drying process, it is essential to carefully monitor the moisture content of the plums. Dried plums (prunes) typically contain around 20-25% moisture to ensure they are dry enough to prevent microbial growth while still maintaining their texture and flavor.

Moisture Testing Techniques:

• Loss on Drying (LOD): This method involves weighing the plums before and after drying to determine the percentage of water removed.
• Moisture Analyzers: These devices use heat and sensors to measure the moisture content of the plums accurately.

Effect of Moisture Content:

• Too high moisture content (above 25%) can lead to spoilage, mold growth, and reduced shelf life.
• Too low moisture content (below 20%) can cause the plums to become overly dry, resulting in a loss of texture and flavor.

5. Cooling and Packaging

Once the plums are dried to the desired moisture level, they undergo a cooling process before being packaged. Cooling is important to prevent condensation and moisture buildup inside the packaging, which could lead to spoilage or mold growth.

Cooling Process:

• Cooling tunnels or airflow systems are used to lower the temperature of the dried plums, making them ready for packaging.
• The cooling process ensures that the plums maintain their quality and texture after the drying process.

Packaging:

• Airtight packaging is used to protect the plums from air, light, and moisture.
• Vacuum sealing or modified atmosphere packaging (MAP) can also be used to extend shelf life and maintain freshness.

6. Quality Control and Final Product Testing

At each stage of the drying process, quality control is carried out to ensure that the dried plums meet food safety standards and quality requirements. This includes checking for the correct moisture content, texture, appearance, and taste.

Laboratory testing may also be performed to check for contaminants, such as pesticide residues or microbial contamination.

7. Conclusion

The industrial drying process of dried plums (prunes) involves a carefully controlled series of steps designed to preserve the natural flavor, texture, and nutritional content of the fruit while ensuring it is safe for consumption and has a long shelf life. From harvesting and pre-treatment to drying, cooling, and packaging, each step is crucial for producing high-quality dried plums that retain their natural sweetness, fiber, and beneficial compounds.

Cultivation Information for Plums (Prunes)

The cultivation of plums, particularly those used for drying (prunes), involves a complex process that requires attention to detail in selecting the right soil, climate, and cultivation techniques. Plums are grown in a variety of conditions worldwide, but optimal cultivation practices are key to producing high-quality fruit for both fresh consumption and dried products.

1. Ideal Growing Conditions for Plums

Plums thrive in temperate climates, and the best conditions for cultivating them involve a combination of moderate temperatures, well-drained soil, and appropriate sunlight. There are two main categories of plum trees used for dried plums (prunes): European plums (Prunus domestica) and Japanese plums (Prunus salicina), with the former being more commonly used for drying purposes due to its higher sugar content and firmer texture.

Climate Requirements:

• Temperature: Plums require a temperate climate with cold winters and warm, sunny summers. The ideal growing temperature ranges from 15°C (59°F) to 24°C (75°F) during the growing season. They need a winter chill to promote dormancy and flowering in the spring, but prolonged freezing temperatures can damage the trees.
• Frost Sensitivity: Plums are sensitive to late frosts during the blooming and fruit-setting phases. Frost damage can severely impact fruit production, so growers must choose the right planting time and location to minimize frost risk.
• Sunlight: Full sun exposure is essential for plums. They need a minimum of 6 hours of direct sunlight per day to achieve the best fruit quality, sweetness, and overall growth.

Soil Conditions:

• Soil Type: Plums prefer loamy, well-drained soils that are slightly acidic to neutral in pH (around 6.0 to 7.5). Soil that retains moisture without becoming waterlogged is ideal. Sandy loam or clay loam soils are most often recommended for plum cultivation.
• Soil Drainage: Good drainage is crucial, as plums do not tolerate "wet feet." Poorly drained soil can lead to root rot and fungal diseases that compromise fruit quality and tree health.
• Soil Fertility: Plums require nutrient-rich soil for healthy growth. The soil should have high organic matter content to improve structure and water retention. Fertilization can be tailored to the specific needs of the trees, particularly when it comes to nitrogen, phosphorus, and potassium levels.

Watering Requirements:

• Watering Frequency: Plums require consistent but moderate watering. During the growing season, they need regular irrigation to keep the soil moist but not soggy. Overwatering can lead to root diseases, while insufficient water can lead to poor fruit development.
• Drought Resistance: Once established, plum trees are relatively drought-tolerant, but to ensure high yields and quality fruit, regular watering is essential during dry spells, especially when the fruit is maturing.

2. Planting and Spacing of Plum Trees

When planting plum trees, careful attention must be paid to the spacing and planting depth to allow for healthy root development and airflow around the trees.

Planting Depth:

• Plums should be planted at a depth where the root collar (where the roots meet the trunk) is level with the surrounding soil. Planting too deep can cause rot, while planting too shallow can expose the roots to air and drought stress.

Tree Spacing:

• Spacing: For commercial plum orchards, trees are typically spaced between 2.5 to 4 meters (8 to 13 feet) apart, depending on the rootstock used and the tree variety. Adequate spacing allows the trees to spread out, reducing competition for nutrients and sunlight.
• Row Spacing: The rows should be at least 4 to 5 meters (13 to 16 feet) apart to allow for mechanical harvesting equipment and proper air circulation between trees.

Rootstocks:

• The choice of rootstock is essential for determining the tree's size, disease resistance, and yield. Dwarf rootstocks are commonly used for small orchards where easy harvesting is important, while standard rootstocks are used in larger commercial orchards where space is not a constraint.

3. Pruning and Maintenance

Pruning is a vital practice for plum trees to ensure strong tree structure, optimal air circulation, and healthy fruit production. Regular pruning helps to remove dead or diseased wood, shape the tree, and encourage better sunlight penetration.

Pruning Techniques:

• Training the Trees: Plum trees can be trained into different shapes, such as central leader (single trunk with lateral branches) or open center (a more bushy structure). The central leader system is most commonly used for prunes because it supports a strong central trunk that can withstand the weight of the fruit.
• Annual Pruning: Pruning should be done annually during the dormant period in late winter or early spring before new growth begins. The goal is to maintain a balance between removing excess growth and preserving enough foliage for healthy fruit production.
• Thinning the Fruit: Thinning is essential for plums to avoid overcrowding, which can result in smaller, less flavorful fruit. By removing some of the immature fruit, the remaining plums can grow larger and have better quality.

4. Pollination and Fruit Set

Plums are typically self-pollinating, meaning they do not require another tree to produce fruit, but having compatible pollinators nearby can significantly increase yields. Cross-pollination can improve fruit size, color, and overall yield.

Pollination Considerations:

• Bees and Insects: Pollination is mostly carried out by bees, but other insects such as flies can also assist in transferring pollen between flowers.
• Flowering: Plums generally flower in early spring, but the timing can vary depending on the variety and local climate conditions. It's important that the flowers are not damaged by late frosts during this critical period.

5. Pest and Disease Management

Plum trees are susceptible to a variety of pests and diseases that can affect both the quantity and quality of the fruit. Integrated pest management (IPM) is often used in plum orchards to minimize the use of chemical pesticides while effectively controlling problems.

Common Pests:

• Aphids: These small insects suck sap from the leaves and stems, which can weaken the tree and lead to reduced growth.
• Plum Curculio: This pest lays eggs on the fruit, and its larvae burrow into the plums, causing fruit drop and deformities.
• Codling Moths: The larvae of codling moths can bore into plums, damaging the flesh and making them susceptible to rot.

Common Diseases:

• Brown Rot: A fungal disease that affects the fruit, causing them to rot and become mushy. It is often spread by rain and high humidity.
• Powdery Mildew: This fungal disease affects the leaves and fruit, causing a white, powdery coating and affecting overall tree health.
• Plum Leaf Spot: A fungal infection that causes spots on the leaves, leading to premature leaf drop and weakened trees.

6. Harvesting and Post-Harvest Handling

Plums are typically harvested when they are fully ripe and have reached their peak sweetness. For prune production, the plums are usually harvested slightly earlier to ensure they have a firmer texture and higher sugar content, which is ideal for the drying process.

Harvesting Methods:

• Hand Harvesting: This method is labor-intensive but allows for careful selection of ripe fruit. It is most common in smaller orchards or when the plums are intended for high-quality dried fruit production.
• Mechanical Harvesting: Larger orchards may use mechanical harvesters to shake the plums off the trees. However, this method is only suitable for plums that are not overly delicate or prone to bruising.

Post-Harvest Handling:

After harvesting, plums are carefully handled to avoid bruising or damage. The plums are then transported to packing facilities where they are washed, sorted, and prepared for either fresh sale or drying. For prune production, plums are quickly transported to drying facilities to undergo the drying process.

The cultivation of plums for dried products is a complex but rewarding process that requires careful attention to the growing conditions, tree maintenance, pest and disease management, and harvesting techniques. By focusing on the ideal climate, high-quality soil, and precise farming practices, growers can produce plums that are perfect for drying into prunes, ensuring a nutritious, sweet, and flavorful product for consumers. At Shulide, we pride ourselves on sourcing high-quality plums grown under optimal conditions, allowing us to deliver premium dried plums with exceptional taste and health benefits.

Global Price and Major Producers of Plums (Prunes)

The global price of plums, especially those cultivated for drying into prunes, is influenced by various factors including supply and demand, agricultural conditions, and market trends. Additionally, the biggest plum producers around the world play a significant role in setting prices, as they contribute the most to global production.

1. Global Price of Plums (Prunes)

The price of plums can vary based on factors such as the type (fresh vs dried), market conditions, and regional differences. On average, the price of fresh plums in the global market is typically lower than dried plums (prunes) due to the added processing involved in drying.

• Fresh plums are usually priced lower, with the cost dependent on the local market and harvesting season.
• Dried plums (prunes) are priced higher due to the processing and preservation involved, especially those that undergo premium drying methods like freeze-drying.
• Premium dried prunes can fetch higher prices as they are marketed as healthier and often used for specific health-related purposes.

2. Major Global Producers of Plums (Prunes)

Plum production is concentrated in a few key regions around the world. The United States, China, and Chile are among the largest producers of plums, particularly for the purpose of drying them into prunes. Below is a summary of the top producers and their contributions to the global plum market.

3. Factors Influencing the Price of Plums (Prunes)

Several key factors contribute to price fluctuations and variations in global markets for plums and prunes:

1. Harvesting Conditions:
   • Weather conditions (frosts, droughts, or excess rain) can affect the quantity and quality of plums produced in major regions.
   • Poor harvests in large-producing countries like China or the U.S. can lead to higher prices for dried prunes.
2. Global Demand:
   • Countries with high consumption rates of dried fruits, such as the United States, Germany, and France, drive demand for prunes.
   • Health trends promoting prunes for their digestive benefits and other health advantages also contribute to price increases.
3. Processing Methods:
   • Different drying methods, such as sun drying, hot air drying, or freeze-drying, can affect the final cost of dried prunes.
   • Higher-quality dried prunes, often made with gentler drying processes (such as freeze-drying), tend to be more expensive.
4. Trade Policies and Tariffs:
   • Export and import regulations, such as tariffs or trade restrictions, can influence prices. For example, trade agreements between the EU and Chile might impact the cost of Chilean prunes in European markets.
5. Global Supply Chain Disruptions:
   • The ongoing logistics challenges or changes in shipping costs can impact the overall availability and cost of plums and prunes in international markets.

4. The Economic Impact of Plum Production

Plum cultivation, especially for dried prunes, has a significant economic impact on both local communities and national economies in major producing countries.

• In California (USA), the prune industry contributes hundreds of millions of dollars annually to the local economy, supporting thousands of jobs in agriculture, processing, and distribution.
• In China, plums are an important part of both domestic consumption and export markets, although they are less commonly dried compared to other regions.
• Chile has become a significant player in the prune export market, especially in Europe and the Americas, with a focus on premium quality dried plums for export.
