Temperature management and preservation key points in garlic seedling cold storage

Garlic sprouts are a common vegetable on the dining table, with a delicious, fragrant, and nutritious taste. Due to the fact that the harvesting period for garlic seedlings is usually from April to July, which is the season when temperatures rise, garlic seedlings are prone to decay and deterioration. Therefore, using a cold storage for garlic seedlings is an effective means to extend their shelf life, ensure their freshness and quality.

Temperature management is one of the key factors for the preservation of garlic seedlings in cold storage. The optimal storage temperature for garlic sprouts is usually between 0 ° C and 2 ° C. This temperature range can effectively reduce respiration and enzyme activity, slow down the aging rate of garlic seedlings, and prevent them from turning yellow and losing water. Maintaining a stable low-temperature environment helps to extend the shelf life of garlic seedlings, keeping them fresh and available for consumption for a longer period of time.

Humidity control is also an important link in the preservation of garlic seedlings in cold storage. The relative humidity inside the garlic seedling cold storage should be maintained between 80% and 90%. Excessive humidity may cause garlic seedlings to rot and mold growth, while low humidity can cause garlic seedlings to lose moisture, become dry and odorless. Maintaining appropriate humidity can help garlic seedlings maintain freshness and taste, while reducing quality loss.

Ventilation is also an important factor in the preservation of garlic seedlings in cold storage. A good ventilation system can ensure air flow, reduce carbon dioxide accumulation, and replenish fresh oxygen. Proper ventilation helps to control the uniformity of temperature and humidity, prevent uneven heating and cooling, and thus maintain the quality of garlic seedlings. Regular cleaning and maintenance of ventilation equipment to ensure its normal operation is a necessary step to maintain good ventilation effects.

In addition, the following preservation points need to be noted:

• Avoid storing garlic sprouts together with fruits or other items that emit ethylene gas to prevent odor contamination.
• Regularly check the quality of garlic seedlings and promptly deal with damaged or pest infested garlic seedlings.
• Keep the cold storage clean and hygienic, and ensure that storage containers and packaging materials meet food safety standards.

Through correct temperature management and preservation points, garlic seedling cold storage can extend the shelf life of garlic seedlings, ensuring their freshness and quality. Agricultural producers and cold storage management personnel should closely monitor temperature, humidity, ventilation, and other preservation measures to ensure that garlic seedlings remain fresh during storage, meet market demand, and improve economic benefits.
