Controlled Atmosphere (CA) and Modified Atmosphere (MA) Chambers
CA and MA chambers are primarily cold storage solutions that help extend the shelf-life of fruits, vegetables, grains, and other food items including dry fruits. By controlling the gaseous environment in these units, you can effectively reduce the rate of respiration, microbial growth, and enzymatic spoilage or browning. This is where the main difference between CA and MA comes in. It is the stable control of various gases including CO2, O2, N2, and ethane that can help store different types of products for an extended period of time.
