Passion fruit is a tropical fruit with a unique aroma and taste, which is deeply loved by consumers. To maintain the freshness and quality of passion fruit, cold storage is a common method. This article will introduce the precautions to be taken when storing passion fruit in cold storage.

1、 The Importance of Passion Fruit Cold Storage Preservation

Passion fruit is a perishable fruit that is susceptible to oxidation and microbial damage. Therefore, storing passion fruit in a cold storage can extend its shelf life, maintain its freshness and taste, and reduce loss and waste.

2、 Suitable conditions for storage of passion fruit in cold storage

1. Temperature: The suitable storage temperature for passion fruit is 5 ℃ -10 ℃. Low or high temperatures can affect the quality of the fruit.

2. Humidity: The suitable humidity for passion fruit is 85% -90%. Excessive humidity can cause fruit decay, while low humidity can cause fruit dehydration.

3. Ventilation: Good ventilation should be maintained in the cold storage to prevent fruits from being affected by the accumulation of carbon dioxide and ethylene.

3、 Precautions for storing passion fruit in cold storage

1. Fruit selection: Fruits with moderate maturity and no pests or diseases should be selected for cold storage.

2. Cleaning treatment: Before storing passion fruit, the fruit should be cleaned to remove surface dirt.

3. Packaging method: Passion fruit should be packaged with breathable packaging materials to maintain the freshness and taste of the fruit.

4. Avoid squeezing: During storage and transportation, excessive squeezing of the fruit should be avoided to prevent damage and deformation of the fruit.

4、 Common problems and solutions for storing passion fruit in cold storage

1. Fruit decay: It may be caused by high temperature or humidity, and the temperature and humidity of the cold storage should be adjusted in a timely manner.

2. Fruit dehydration: It may be caused by low humidity, and the humidity in the cold storage should be increased.

3. Fruit discoloration: It may be caused by oxidation reactions, and the contact time between the fruit and air should be minimized as much as possible.

5、 Supervision and inspection of storage of passion fruit in cold storage

In order to ensure the quality and safety of storage in passion fruit cold storage, relevant departments should strengthen supervision and inspection of cold storage. Regularly inspect the temperature and humidity, ventilation, and fruit quality of the cold storage, and promptly rectify and handle any problems found.

In summary, precautions for storing passion fruit in cold storage include appropriate temperature and humidity conditions, fruit selection and processing, packaging methods, and avoiding fruit compression. Only by doing a good job in these aspects can we extend the shelf life of passion fruit, maintain its freshness and taste, and meet the needs of consumers. Relevant departments should strengthen supervision and inspection of cold storage to ensure the quality and safety of passion fruit storage。

 The advantages of fresh-keeping warehouses
