Activated carbon can be utilized in the preservation of fruits and vegetables by helping to extend their shelf life and maintain their quality.

Ethylene gas is naturally produced by fruits and vegetables and is responsible for their ripening and senescence. However, excess ethylene can accelerate the spoilage process. Activated carbon can be used to adsorb and remove ethylene from storage environments, slowing down the ripening and extending the freshness of produce.

Activated carbon has a high adsorption capacity for various volatile organic compounds (VOCs) that contribute to the aroma and off-odors in fruits and vegetables. Incorporating activated carbon can help reduce the concentration of these compounds, maintaining the desirable aroma and flavor of the produce.

Activated carbon can adsorb moisture, which is beneficial for controlling humidity levels in storage environments. By maintaining proper humidity, the growth of molds, fungi, and bacteria can be inhibited, reducing spoilage and decay.

Fruits and vegetables continue to respire even after being harvested. This respiration can lead to moisture loss, wilting, and quality deterioration. Activated carbon can help manage the storage environment by maintaining optimal humidity levels, slowing down respiration, and preserving the appearance and texture of produce.

By controlling ethylene gas, moisture, and microbial growth, activated carbon contributes to extending the shelf life of fruits and vegetables. This is particularly important for items that are sensitive to ethylene-induced ripening and that have a short shelf life.

Activated carbon can be incorporated into modified atmosphere packaging to help maintain the desired gas composition within the packaging. This helps regulate the levels of oxygen and carbon dioxide, which can further contribute to the preservation of produce.

Activated carbon can help adsorb volatile compounds that might otherwise migrate from one type of produce to another, reducing the potential for cross-contamination and preserving the distinct flavors and aromas of different items.
