The Ultimate Guide to Preserving Fresh Grapes: Unveiling the Secrets to Longer-Lasting Fruit

Longan is a popular fruit among many due to its tender, juicy flesh, sweet flavor, and unique aroma. However, this fruit is highly perishable if not stored properly. Here, we will introduce to you a comprehensive guide on how to keep longan fresh, with effective methods that will ensure your longan stays vibrant and tasty. Don’t miss out on these helpful tips!

1 Preserving Fresh Longan After Harvest

Longan is prone to water loss and quality degradation post-harvest, influenced by factors such as fruit type, light, temperature, and humidity. To counter this, follow these steps when storing fresh longan:

Choose intact, ripe longan for longer preservation

Step 1 Discard any longan that is cracked, bruised, insect-damaged, moldy, or diseased. Only keep those that are intact and in good condition.

Step 2 Store longan in a well-ventilated, shaded area.

Step 3 Cover the longan with a damp cloth (or wet paper towels) to maintain moisture.

2 Preserving Fresh Longan During Transportation

Transportation Without Refrigerated Trucks

To ensure the freshness of longan during long-distance transportation, refrigerated trucks are ideal. However, they may not always be available. In such cases, follow these steps to keep your longan fresh:

Place longan in a styrofoam box

Step 1 Arrange longan in a transport box.

Step 2 Do not overcrowd the box; ensure there is adequate space between clusters of longan.

Step 3 Cover the surface of the box with damp towels to shield the longan from direct sunlight.

Step 4 Transport immediately.

Transportation With Refrigerated Trucks

While the above method maintains freshness, it requires same-day transportation. For longer journeys of 10 to 15 days, refrigerated trucks are necessary. Follow these steps to keep longan fresh during transportation:

Refrigerated trucks can preserve longan for 10 to 15 days

Step 1 Treat the longan with SO2 gas to eliminate mold and decay-causing agents.

Step 2 Arrange the longan in boxes, ensuring adequate spacing between clusters.

Step 3 Store the longan in the refrigerated truck, maintaining a temperature between 5 and 10°C and humidity above 90%.

Step 4 Transport the goods for up to 10 to 15 days.

3 Storing Fresh Longan in the Fridge

Storing Longan in the Chiller Compartment

Once you’ve purchased fresh longan, how do you keep them fresh at home? If you can’t finish them all at once, store them in the chiller compartment of your fridge by following these steps:

Separate longan fruits from the branch

Step 1 Wash the longan, separate the fruits from the branch, and let them air dry.

Step 2 Discard any damaged, rotten, or moldy longan, as well as those showing signs of pest infestation.

Step 3 Place the longan in a perforated plastic bag and store it in the chiller compartment of your fridge.

When storing longan in the chiller, keep the following in mind:

Perforated plastic bag for longan storage

• Use perforated bags to allow air circulation.
• Divide the longan into smaller portions based on your consumption needs.
• Keep the bag of longan on a separate tray in the chiller compartment.

Storing Longan in the Freezer

Not just the chiller, but the freezer is also a great option for long-term longan storage. This method can help you preserve longan for up to a year! To store longan in the freezer, follow these simple steps:

Longan flesh after removing the shell and seed

Step 1 . You may also choose to remove only the shell or both the shell and seed, but keeping the seed intact helps maintain the texture of the longan flesh better.

Step 2 Place the deseeded longan in a container.

Step 3 Put the container in the freezer for long-term storage.

Although this method prolongs the shelf life of longan, the quality of the fruit may deteriorate upon thawing, leading to increased water release and softness. Hence, this method is typically used for longan intended for smoothies or dessert preparations like cakes, ice cream, and more.

4 Important Notes for Preserving Fresh Longan

The above methods are highly effective for longan preservation, but to ensure the best quality, keep the following in mind:

• The process of separating longan flesh from the shell (or shell and seed) should be done promptly, ideally within 4 hours, to maintain the freshness of the fruit.

Shelling longan should be done quickly, ideally within 4 hours

• If you opt for freezer storage, it is recommended to place the longan flesh in the freezer for about half an hour before transferring it to an airtight container, as mentioned earlier. This helps prevent water release during thawing.
• You can also cook the longan flesh with sugar and apply high-pressure sealing to achieve long-term preservation while maintaining freshness.
