Food Preservation Activated Carbon Mechanism
Adsorption Process
You can think of adsorption as a process where molecules stick to the surface of a solid. Food Preservation Activated Carbon works because it has a huge surface area and many tiny pores. These pores act like traps for gases and moisture that cause food to spoil.
Adsorption is an exothermic process. This means it gives off heat when molecules attach to the carbon.
The pore structure is important. Different pore sizes catch different types of molecules, like ethylene, oxygen, or water vapor.
You need enough contact time for the process to work well. The longer the food stays near the activated carbon, the more spoilage agents get trapped.
Temperature can change how well adsorption works. Moderate heat can help, but too much heat can damage the pores.
The structure of activated carbon makes it very effective in food preservation. The large surface area and pore volume help remove unwanted odors, flavors, and moisture from your food. This keeps your food tasting and smelling fresh.
Activated carbon enhances ethylene absorption efficiency in controlled environments, which helps in trapping and neutralizing ethylene gas, thereby slowing down the ripening process of perishable goods.
Ethylene and Spoilage Control
Ethylene is a natural gas that fruits and vegetables produce. It speeds up ripening and can make food spoil faster. Food Preservation Activated Carbon helps by removing ethylene from the air around your food.
