Controlled Atmosphere Storage for Fruits and Vegetables

The storage of fruits and vegetables, and particularly produce such as apples and pears, can be optimized with the use of Controlled Atmosphere Storage.  This process works by maintaining specific settings for elements including temperature, oxygen, carbon dioxide, and humidity.  The controlled atmosphere allows produce to remain fresh and crisp longer because the ripening process is significantly slowed.

Fruits and vegetables that "breathe" ripen through the process of taking in oxygen and giving off carbon dioxide.  By controlling how much oxygen and carbon dioxide circulates throughout the storage room, the ripening process can be altered to ensure that fruits are still fresh by the time they reach their destination.  We've written about this slowed ripening process in a previous blog post here: Controlled Atmosphere Storage Using Nitrogen

Using Nitrogen for Controlled Atmosphere Storage

Nitrogen gas is used to control the atmosphere of the storage room because it is an inert gas that can displace and reduce the presence of oxygen which also decreases the humidity level.  Limiting oxygen and humidity using nitrogen gas will help slow the fruit's ripening process and preserve freshness for a longer period of time.

Nitrogen generating systems installed at the point of process for Controlled Atmosphere Storage are a safe and reliable alternative to liquid N2 gas stored in high pressure cylinders.  South-Tek Systems is a leading manufacturer of Nitrogen Generators used in a wide variety of applications, including food packaging, modified atmosphere packaging, and controlled atmosphere storage.
