Controlled atmosphere storage involves maintaining a specific composition of gases (such as oxygen, carbon dioxide, and nitrogen) at precise levels to prolong the shelf life of perishable products, often using advanced monitoring systems. In contrast, modified atmosphere storage alters the atmosphere within a sealed package or storage unit, but typically does not maintain the strict control over gas concentrations found in controlled atmosphere systems. While controlled atmosphere storage is often used for long-term storage, modified atmosphere storage is commonly employed for shorter periods, particularly in transportation and retail settings. Additionally, controlled atmosphere systems are usually more complex and costly due to their continuous monitoring and adjustment capabilities.
There is little difference between controlled and modified atmospheres. They both refer to atmospheres where the proportions of the normal gaseous/vapor components oxygen, nitrogen, carbon dioxide and water vapor, are modified to achieve some storage/packaging goal. This is commonly lowering the oxygen and/or increasing the carbon dioxide. All such atmospheres are modified atmospheres, they become controlled atmospheres when an attempt is made to regulate the composition of one or more of component gases.

A packaging gas is any gas used to provide a modified atmosphere for a product in storage.
Modified stems have been altered by the parent plant to fit the needs of the plant. There are three examples I will be stating here. First, there are the stolon. They grow horizontally along the ground and they grow above the ground. An example would be strawberries. Next, there are the tuber stems. They are enlarged underground stems that are for starch storage. An example of this would be potatoes. Finally, there are the succulent stems. They are fleshy and often leafless. They are used for water storage. An example would be cacti.
Its where the atmosphere in which a product is tored/kept is changed, i.e. oxygen is removed from the air of pre-prepared salads and other gases are added, this makes it MAP
Controlled release OxyContin is designed to release the medication over a specific period to provide consistent pain relief, while modified release OxyContin may release the medication at different rates based on the formulation, but still provides extended pain relief. Controlled-release OxyContin is often used for chronic pain management where consistent blood levels are required, while modified-release OxyContin may be used for varying durations of pain relief.
Reference: Food Packaging, Principles and Practice by Gordon L.Robertson CAP is the enclosure of food in a gas impermeable package inside which the gaseous environment with respect to CO2, O2, N2, water vapor and trace gases has been changed and is selectively controlled to increase shelf life. O2 scavengers and ethylene absorbers with CO2 release agents could be classified as CAP during the early stages of the storage life of packaged product. MAP is the enclosure of food in a package in which the athmosphere inside the package is modified so that its composition is other than that of air. Modification can be achieved by removing air and replacing it with a controlled mixture of gases. Nitrogen is frequently used in MAP to reduce the concentration of other gases in the package.
