Grape cold storage technology
To ensure high-quality grape storage, it's essential to carefully select the right varieties and follow a systematic process. First, choose hard and crisp grape varieties that are less prone to softening during storage. Varieties like Kyoho and Global Red are ideal due to their thick skin, waxy coating, and large fruit size. These characteristics help protect the grapes from damage and maintain freshness over time.
Harvesting should take place after the morning dew has dried to avoid excess moisture. If there was moderate rain or irrigation before harvesting, it's best to delay the process for at least one week. Select only fully matured grapes with uniform color and size, and remove any diseased, damaged, or residual fruits. To prevent bacterial contamination, apply a light vinegar spray before harvesting.
Certain grapes should not be stored under any circumstances: those that are unripe (sugar content below 14%), soft-berried types, grapes harvested before or during heavy rain, those affected by downy mildew, rotten or green fruits, and those damaged by natural disasters such as frost or locust infestations.
Before storage, disinfect the warehouse using potassium permanganate for one week. Clean all surfaces, including the ceiling and floor. Additionally, fumigate the storage area with 2 kg of sulfur in a 20-ton tank for three days to eliminate pathogens.
Pre-cooling is crucial. When transporting grapes in 20 kg plastic bins, keep them shaded during the day and store them in a cool place at night. Cool the grapes quickly to -1°C to reduce respiration and ethylene production. For Kyoho grapes, pre-cooling should not exceed 12 hours to avoid stem drying. For small-bagged grapes, open the packaging to release field heat and moisture before sealing it in a cooling room.
For storage, pack the pre-chilled grapes in sorghum baskets, using 3 tons per batch (about 20 baskets). Each basket should contain 10 preservative packets. Seal the baskets with plastic film to create an isolated micro-environment. The preservatives release fresh air evenly, maintaining optimal humidity and reducing the risk of phytotoxicity. The enclosed space also limits oxygen levels, slowing respiration and extending shelf life. Condensation forms on the inner walls of the plastic but does not touch the fruit, keeping it clean and intact.
During storage management, after placing all grapes in the warehouse, burn a small amount of sulfur between the layers to kill any pathogens. Close the doors and ignite the sulfur to ensure proper fumigation. The warehouse should be temperature-controlled, maintaining a range of -2 to 0°C. No personnel should enter the warehouse; temperature adjustments are handled automatically. The temperature inside the plastic film may be about 1°C higher than outside, which helps regulate humidity and prevent condensation on the fruit.
Midway through storage, ventilate the warehouse once and then re-fumigate with sulfur. After two months, replace the plastic wrap with fresh ones without turning the grapes, allowing for quality checks. This method is cost-effective, easy to implement, and reusable. Over recent years, this technique has achieved up to 8 months of storage with a preservation rate of over 95%, making it highly valuable for simple and efficient grape storage.
